Oh yea Gina did a great job last night
I really like her too. She stands out because she has a style all her own as well as a great voice. I hope she gets a contract out of this exposure.
I thought last night was great, never saw that sm
coming. I couldn't believe Eric. The jury was hilarious and I agree with James, he's not the dumbest survivor anymore. At least Eric didn't look like he was very upset, he went off laughing about "those girls" unlike Ozzy who was really ticked off. I didn't like how Cirie played the game this year but I like the other 3 girls. Parv or Amanda will win in the end.
A friend sent me this last night. It is great!!!

Saw Momma Mia Saturday night and it is great! SM
The theater was packed, and even the men in the crowd were laughing and enjoying it. At the end the people in the theater broke into a loud applause! It was a light, funny movie with all those great songs!
We are die-hard Steeler fans and it was a great game last night...
The Cardinals played great and you couldn't ask for a better game, although I am glad my team came out in the end...Go Steelers!!!
If you who have kids or grandkids check out the lunar eclipse tonight....
at least they'll have something cool to contribute at school in the morning, you get to spend time with them and they may actually be interested. Or you can just have a special moment with your spouse thinking about the first lunar eclipse you saw together. Have fun! Cat
Path of the Moon through Earth's umbral and penumbral shadows during the Total Lunar Eclipse of February 20, 2008. (Eastern Standard Time)
Introduction
A total eclipse of the Moon occurs during the night of Wednesday, February 20/21, 2008. The entire event is visible from South America and most of North America (on Feb. 20) as well as Western Europe, Africa, and western Asia (on Feb. 21). During a total lunar eclipse, the Moon's disk can take on a dramatically colorful appearance from bright orange to blood red to dark brown and (rarely) very dark gray.
An eclipse of the Moon can only take place at Full Moon, and only if the Moon passes through some portion of Earth's shadow. The shadow is actually composed of two cone-shaped parts, one nested inside the other. The outer shadow or penumbra is a zone where Earth blocks some (but not all) of the Sun's rays. In contrast, the inner shadow or umbra is a region where Earth blocks all direct sunlight from reaching the Moon.
If only part of the Moon passes through the umbra, a partial eclipse is seen. However, if the entire Moon passes through the umbral shadow, then a total eclipse of the Moon occurs. For more information on how, what, why, where and when of lunar eclipses, see the special web page lunar eclipses for beginners.
Lunar Eclipse Diagrams
The following diagrams show the Moon's path through Earth's shadows (higher resolution versions of the above figure). The times of major stages of the eclipse are given for a number of time zones in North America. Please choose the diagram for your own time zone. Each diagram is a GIF file with a size of about 100k.
Some people may be puzzled that the Moon's motion is from west to east (right to left) in these diagrams, instead of its daily east to west (left to right) motion in the sky. However, the Moon actually moves WEST to EAST (right to left in the Northern Hemisphere) with respect to the Earth's shadow and the stars.
Times and Phases of the Total Lunar Eclipse of February 20/21, 2008
From start to finish, February's lunar eclipse lasts about three hours and twenty-six minutes (not including the penumbral phases which are very difficult to see). The partial eclipse begins as the Moon's eastern edge slowly moves into the Earth's umbral shadow. During the partial phases, it takes just over an hour for the Moon's orbital motion to carry it entirely within the Earth's dark umbra. The color and brightness of the totally eclipsed Moon can vary considerably from one eclipse to another. Dark eclipses are caused by volcanic gas and dust which filters and blocks much of the Sun's light from reaching the Moon. But since no major volcanic eruptions have taken place recently, the Moon will probably take on a vivid red or orange color during the total phase. After the total phase ends, it is once again followed by a partial eclipse as the Moon gradually leaves the umbral shadow.
The total phase of a lunar eclipse is called totality. At this time, the Moon is completely immersed within the Earth's dark umbral shadow. During the February 20 eclipse totality will last just under 50 minutes. This is quite a bit less than the last total lunar eclipse ( August 28, 2007) which lasted 90 minutes.
The major phases of the eclipse occur as follows (all times are GMT or Greenwich Mean Time). The partial eclipse commences with first umbral contact at 01:43 GMT. Totality begins at 03:01 GMT and lasts until 03:51 GMT. The partial phases end at 05:09 GMT. Eclipse times for time zones in the United States and Canada are shown in the following table.

Visibility of the Total Lunar Eclipse of February 20, 2008
February's lunar eclipse is well-placed for North and South America as well as Europe and Africa. Observers along North America's west coast miss the early stages of the partial eclipse because it begins before moon rise. Alaskans in Anchorage and Fairbanks experience moonrise during totality but bright evening twilight will make it difficult for sourdoughs to view the event. Western Europe and northwest Africa also see the entire eclipse. Further to the east (east Africa and central Asia), the Moon sets before the eclipse ends. None of the eclipse is visible from eastern Asia or Australia.
Preceeding and following the eclipse are hour-long penumbral phases but these are faint and quite difficult to see. The more interesting and photogenic partial and total phases always take center stage to the penumbral phases.

The map above shows the geographic regions of visibility for each phase of the eclipse. The entire eclipse is visible from start to finish in the white (unshaded) portion of the map, while none of the eclipse can be seen from the dark gray areas.
For anyone located in the blue shaded region labeled Eclipse at Moonset, this means that the Moon will set while some phase of the eclipse is already in progress. The contact curves labeled P1, U1, U2, U3, U4, and P4 represent each phase of the eclipse (see the key above). If you are east (right) of a particular curve, that phase occurs after moonset and you will not see it. However, if you are west (left) of a curve, that phase occurs before moonset and you will see it (weather permitting).
For example, on the above map Turkey lies west (left) of the U3 curve (total eclipse end) and east (right) of the curve U4 (partial eclipse ends). This means that from this region, the Moon sets during the partial phases following totality.
For observers located within the second blue shaded region labeled Eclipse at Moonrise, the situation is reversed. Here the Moon rises while some phase of the eclipse is already in progress. If you are west (left) of a particular curve (P1, U1, U2, U3, U4, or P4), that phase occurs before moonrise and you will not see it. However, if you are east (right) of a contact curve, that phase occurs after moonrise and you will see it (weather permitting).
All total eclipses start with a penumbral followed by a partial eclipse, and end with a partial followed by a penumbral eclipse (the total eclipse is sandwiched in the middle). Since the penumbral phases of the eclipse are so difficult to see, we will ignore them.
Wonderful Totality
At the instant of mid-totality (03:37 GMT), the Moon will lie in the zenith for observers in French Guiana. At this time, the umbral eclipse magnitude peaks at 1.1062.
From the diagram above, it is clear that the northern (top) edge of the Moon will dip much deeper into the Earth's shadow than will the southern (bottom) edge. Since the Earth's umbral shadow is darker in the center than at the edge, the Moon's appearance will likely change dramatically with time. A large variation in shadow brightness can be expected and observers are encouraged to estimate the Danjon value at different times during totality ( Danjon Brightness Scale). Note that it may also be necessary to assign different Danjon values to different portions of the Moon at different times.
This could be an excellent opportunity for budding astronomers and students to test their observing skills. Try recording your estimates of the Moon's brightness every ten minutes during totality using the Danjon Scale. Compare your results with your companions and classmates and discover how the Moon's appearance changes during the total eclipse. The brightness of the totally eclipsed Moon is very sensitive to the presence of volcanic dust in Earth's atmosphere. As part of a continuing research project, Dr. Richard Keen has been using reports of lunar eclipse brightnesses to calculate a history of optical thicknesses of volcanic dust layers (see: What Will 2004's Lunar Eclipses Look Like?). If you'd like to help Dr. Keen by making eclipse observations, you can contact him at Richard.Keen@Colorado.EDU.
The amount of dust and sulfur dioxide in Earth's atmosphere also has an effect on the diameter of the umbral shadow. Amateur astronomers with telescopes can make careful timings of when some of the Moon's major craters enter or exit the umbra. Such observations are valuable in determining the enlargement of Earth's shadow. A table of crater predictions identifies twenty well-defined craters useful for this purpose. For more information, see: Crater Timings During Lunar Eclipses.
An eclipse of the Moon also presents a tempting subject to photograph. Since the Moon appears quite small in the sky, you'll need a fairly powerful telephoto lens (400 mm or more) or even a small telescope to attach to your camera. A typical ISO 400 speed (either digital or film) is a good choice. For more information on equipment, film, recommended exposures and additional tips, see lunar eclipse photography.
Unlike solar eclipses, lunar eclipses are completely safe to watch. Protective filters are not necessary and neither is a telescope. A lunar eclipse can be observed with nothing more than the naked eye. However, a pair of binoculars will magnify the view and make the red coloration brighter and easier to see. A standard pair of 7x35 or 7x50 binoculars is sufficient.
During the eclipse, the Moon will be in Leo. Saturn and bright star Regulus are only 3 degrees east and west, respectively, of the Moon. Geminii, Orion, Taurus and other winter constellations will occupy the south and western sky for North American eclipse watchers. viewers.
Although total eclipses of the Moon are of limited scientific value, they are remarkably beautiful events which do not require expensive equipment. They help to cultivate interest in science and astronomy in children and to provide a unique learning opportunity for families, students and teachers. To the nature lover and naturalist, the lunar eclipse can be appreciated and celebrated as an event which vividly illustrates our place among the planets in the solar system. The three dimensional reality of our universe comes alive in a graceful celestial ballet as the Moon swings through the Earth's shadow. Hope for clear skies, dress warmly and enjoy the show!
Eclipse Frequency and Future Eclipses
During the five millennium period from 2000 BC through AD 3000, there are 7,718 eclipses[1] of the Moon (including both partial and total eclipses). From 0 to 3 lunar eclipses (partial or total) occur each year. The last time three total lunar eclipses occurred in one calendar year was in 1982. On average, partial eclipses slightly outnumber total eclipses by 7 to 6[2].
[1] Only eclipses where the Moon passes through Earth's umbral shadow are included in these values. A minor type of eclipse is the penumbral eclipse which occurs when the Moon passes through the Earth's faint penumbral shadow. Penumbral eclipses are rarely discernible to the naked eye and are of lesser importance than umbral eclipses.
[2] Penumbral eclipses are excluded from these statistics.
The last total lunar eclipse visible from the entire continental United States occurred on August 28, 2007. North Americans will have their next opportunity to see a total lunar eclipse on 2010 Dec 21.
The table below lists every lunar eclipse from 2007 through 2012. Click on the eclipse Date to see a map and diagram of an eclipse. Although penumbral lunar eclipses are included in this list, they are usually quite difficult to observe because of their subtlety. The penumbra is a partial shadow which still permits some direct sunlight to reach the Moon.
The Umbral Eclipse Magnitude is the fraction on the Moon's diameter immersed in the umbra at maximum eclipse. For values of 1.0 or greater, the eclipse is total. For negative values, the eclipse is penumbral. The Total Duration is the duration of the total phase (total eclipses only).

Path of the Moon through Earth's umbral and penumbral shadows during the Total Lunar Eclipse of February 20, 2008. (Eastern Standard Time)

A lunar eclipse can be observed with nothing more than the naked eye. However, a pair of binoculars will magnify the view and make the red coloration brighter and easier to see. A standard pair of 7x35 or 7x50 binoculars is sufficient.
During the eclipse, the Moon will be in Leo. Saturn and bright star Regulus are only 3 degrees east and west, respectively, of the Moon. Geminii, Orion, Taurus and other winter constellations will occupy the south and western sky for North American eclipse watchers. viewers.
Although total eclipses of the Moon are of limited scientific value, they are remarkably beautiful events which do not require expensive equipment. They help to cultivate interest in science and astronomy in children and to provide a unique learning opportunity for families, students and teachers. To the nature lover and naturalist, the lunar eclipse can be appreciated and celebrated as an event which vividly illustrates our place among the planets in the solar system. The three dimensional reality of our universe comes alive in a graceful celestial ballet as the Moon swings through the Earth's shadow. Hope for clear skies, dress warmly and enjoy the show!
Eclipse Frequency and Future Eclipses
During the five millennium period from 2000 BC through AD 3000, there are 7,718 eclipses[1] of the Moon (including both partial and total eclipses). From 0 to 3 lunar eclipses (partial or total) occur each year. The last time three total lunar eclipses occurred in one calendar year was in 1982. On average, partial eclipses slightly outnumber total eclipses by 7 to 6[2].
[1] Only eclipses where the Moon passes through Earth's umbral shadow are included in these values. A minor type of eclipse is the penumbral eclipse which occurs when the Moon passes through the Earth's faint penumbral shadow. Penumbral eclipses are rarely discernible to the naked eye and are of lesser importance than umbral eclipses.
[2] Penumbral eclipses are excluded from these statistics.
The last total lunar eclipse visible from the entire continental United States occurred on August 28, 2007. North Americans will have their next opportunity to see a total lunar eclipse on 2010 Dec 21.
The table below lists every lunar eclipse from 2007 through 2012. Click on the eclipse Date to see a map and diagram of an eclipse. Although penumbral lunar eclipses are included in this list, they are usually quite difficult to observe because of their subtlety. The penumbra is a partial shadow which still permits some direct sunlight to reach the Moon.
The Umbral Eclipse Magnitude is the fraction on the Moon's diameter immersed in the umbra at maximum eclipse. For values of 1.0 or greater, the eclipse is total. For negative values, the eclipse is penumbral. The Total Duration is the duration of the total phase (total eclipses only).

AA degrees
AA, BA are worthless today unless they are in a specialized field. Technical certificates are the way to go now. Companies are looking for skills not paper that says you took 2 or 4 years of college. I make more money than any of my friends who have AA or BA degrees..
It's 23 degrees here
and we're having our first major blizzard. Just got home driving in it. No fun. Did I mention I hate snow?! Inside it's a nice toasty 68. Just watching The Ghost Whisperer and ready for a very early night.
It is 11 degrees here in
However, you need to be clear about what YOU want and not just tell them
that it's their job. You do have some responsibility in this as a parent. Tell them that you expect them to help your daughter get caught up along with the rest of the children who are behind, and that your child being behind is directly due to the result of poor handling during her kindergarten year when there was lengthy teacher absence and that because of that, their rules regarding children having to be 6 months behind academically is moot. You might suggest that they provide a separate classtime with the children who are behind with direct emphasis on only the problem areas and quickly get them back on track. Good luck.
Should have been more clear, huh? - LOL
Thank you, too. It is so very clear to me that SM
you are the type of person to love with all your heart. My sister during the last week of her cat's life slept on the floor with Mary Beth (her beautiful cat of many years) because Mary Beth could no longer jump up and down from the bed. We do things we never thought we would do for these beautiful creatures God has given us. You are such a loving pet owner. That made me cry reading your posts. I celebrate the life of your cat and the love you gave her. I celebrate the life of all the pets my family has owned, loved and still miss. We all feel what you are feeling and you are not alone. Your love enabled you to give her all those years, and I believe your love will get you through.
Let me try to be more clear...lol
I wash my hair with the dandruff shampoo...although I don't have dandruff, it also kills germs that cause acne. I use the facial scrub in the shower to open up my pores so that when I put on the peroxide, it can get into my pores. If you just dab on peroxide without the scrub first, it won't do much.
Please clear something up for me here.
Unless this man's ex-wife was a non-believer, he technically can't have a relationship with any other woman at all because it would be considered adultry....right?
Yes, when it's 90 degrees out, I care about AC. You

100 degrees in PA and my air conditioner is SM
not working! I am sitting here trying to type with water running. Just called Time and Temperature which said 102. Never was a summer person and this is not helping. Hope you are all cool!
As far as snow, it's been clear. But
as far as traffic goes in general, good luck. I live only about 45 minutes away and on a Saturday it can take hours to get in, especially bad at the tunnels, and parking is also the pits, can be very expensive, one time it cost me $40 for a few hours. Is there a train or bus you can take? Good luck and have fun!
Clear up your post, who has
mother issues? Don’t know who you are talking about, sorry.
True, I should have been more clear that my ask to

Re-read that - boy that is clear as mud isn't it? sm
I went to see my family, stayed in an inexpensive condo (cheaper than hotels in the area), realized they had not charged me and told them, now a couple months later they still have not charged me. I want to call again and tell them but I am also very broke. What would you do?
NO, it is NOT clear; Why did your stepbrother's
wife and his children NOT inherit? YOU were NOT the only heir, as you state in your post...
'My father died in 2004, leaving me as his only heir..'
No, there was his wife and his 2 children.
That his wife remarried, does not forfeit her rights to her inheritance from her first husband.
You have nothing to do with them? You are the step-aunt and step-sister-in-law.
How do you know that she married again? It seems that you are withholding evidence to the authorities, so that you can cash in the WHOLE anmount!
It is MORE than obvious!
perhaps I wasn't clear enough for you
My husband accompanied my son to practice. The then assistant coach was trying to make conversation with him. He asked my husband where he worked -- typical question, like how's the weather? My husband answered honestly and left it at that. This guy went on to tell his life story. My husband did not repeat this to anyone other than his supervisor when he realized it was a breach of ethics for him to be around him.
Again, my husband approached the head coach about the situation and without going into detail about the man's criminal history, asked for a transfer. The head coach referred him to the league president, who asked why he needed a transfer. He then told the league president, who does the background checks and would have found out anyway, why he needed the transfer. The league president then informed the head coach, who who told the assistant coach why he decided to remove him from his coaching staff. We certainly did not discuss this with any other parents on the team. We had also requested that the head coach not discuss with the assistant coach until and if it would be necessary. We were hoping to avoid the situation entirely by transferring our child, not the ex-convict's kid. Silly us to think we were doing the right thing?
The last thing we wanted was for any of this to come to light. We tried to handle it discretely. I'm guessing you're also one of those people who likes to make the people trying to do the right thing out to be the bad guy.

Just outside of KC,Mo. with a lovely 8 degrees this morning. nm
It's so hot outside you could fry an egg on the sidewalk, 96 degrees, humid, and hot, hot, hot!!!
Hasn't rained in the past 3 days, frogs were singing some' fierce last night, so I know storms will be here at some point today!
It was over 90 degrees at 9:30 am in South Florida.

Put a rack in the bottom of the pan so the meat is not touching the liquid. Put about a cup or so of water in the bottom of the pain with some cut up onions and a little salt and pepper. Place the roast on the rack, fat side up. No need to cover the roast if you want a good crusty layer of fat on the meat. This also keeps the meat moist.
I have a balmy 17 degrees at noon in PA
It's snowing...again. The kids missed another day of school. One of the only drawbacks of working at home. Can't call the boss and say I'm snowed in! But, yes, definitely looking forward to spring. I was ready for spring the day after Christmas!
7 degrees this morning on my way to school!
Our kids were dismissed early last Thursday because of afternoon snow showers (better to be safe than sorry). They also decided before sending them home on Thursday to close on Friday due to expected cold temperatures. Temps were the same as today, yet we go to school today. I don't get it. We were off Monday for an in-service day, but they always schedule that on King day. So why be off Friday but not today? I'm guessing some higher-ups wanted a 4-1/2-day weekend.
Back in my day (I'm 34), we went to school unless it snowed 2 feet or we got an ice storm. We never got off because it was "too cold". I asked the school secretary about this, who's close to my age, and she agreed about "our day" and said she thinks it has to do with so many parents letting their kids stand at the bus stops for 1/2 hour or more because they don't want to get dressed and drive them to the bus stop and not dressing the kids properly. She said you wouldn't believe the number of kids she sees at school dressed in shorts, etc, in the middle of winter. We live in the Northeast, so it's not like we expect it to be warm this time of year.
I just will never understand some parents. I drive my kids to school every day even though they're on the bus route. The busses are just too cold in the morning and they'd have to get up 1/2 hour earlier and we already get up at 7:15 to be at school by 8. I let them ride the bus home in the afternoon because the buses are warmed up 1/2 hour from picking up the high schoolers first and my kids are only on the bus for 15 minutes. I also make sure my kids have hat, gloves and scarves when it's cold. They don't always wear 'em, but they're in their backpacks if they need them. Why don't some parents care?
Sorry -- off my soapbox. This was just s'posed to be about the weather. It's cold here -- BRRRRR
I only have 1 question - if you hold these degrees
what are you doing on this forum? Why are you not putting your masterful degrees to a better position that would be more than the lowly MT
Tea party, ratcheted up a few degrees. :)

And Thursday night is safer than Friday night - how?
We used to live in a town that was once in the Guiness Book of World Records for number of churches per capita (which by the way was the worst place I've ever lived - discourteous, Nazi schools, etc.), and they wouldn't let us trick or treat on Sundays. Ridiculous! People can say what they want but celebrating Halloween doesn't make you a devil worshiper! Just my 2 cents!
I should have made my post more clear, sorry...
I meant *generally* speaking. You seem to me to rather be the exception to the rule. MOST folks (not you, evidently and this is a GOOD THING *S*) in the deep south (and I am not speaking of places such as south Florida) - are against abortion and pro-choice - not all of them but PLENTY of them.
I did NOT mean to offend....please forgive me....
I made it very clear to the office
before I told them my concerns she was not to know. You aunt seems to have more going on, i.e. being unrealistic about trying to climb all the steps you talk about. You should not feel guilty about trying to explain the situation at your place. Is this your mother's sister- who else can step in and speak up for you? My aunt got sorta snippy with me (never had before) but now since she is having to move seems more calm and more accepting- I think she is actually looking forward to it after wanting to be on her own for all these years. Just could not do it anymore and I applaud her doctor for stepping in like I wanted him to. I went behind her back but she would tell me things and then ask that I not tell her son and her living alone I knew I had to step in which I did. She adores her doctor and I knew this, therefore that is the person I approached.
