The moon will begin eclipsing at 12:32am Central Time the morning of Dec21, it will be fully within the Earth’s shadow from 1:40am – 2:53am, and at 4:01am, it will be over. The eclipse will be visible to the entire western hemisphere the night of Dec 20 through the early morning of Dec 21.

From central Texas, you will be able to observe the moon begin to partially eclipse on its way down, at 5:17am Central time. It will be half eclipsed at the greatest at 6:38am, which is shortly after the moon goes below the horizon in central Texas, and at 8:00am, the eclipse will be over.

Update 6/25/2010 – 5:35pm CST - Less than 12 hours to go before it begins. Since it will be eclipsed as it goes past the horizon, it seem to be magnified by an illusion known as “moon illusion”. Details here.
The chemical reaction featured on Monday Night’s Big Bang Theory, Season 3 Episode 9, “The Vengeance Formulation” (Nov 23, 2009) is known as Elephant’s Toothpaste.
It is done by combining hydrogen peroxide, dishwashing detergent, and saturated solution of potassium iodide. The experiment is detailed at this University of Minnesota Chemistry Department page.
Here is a video explaining the same chemical reaction:
In reference to my other post, Knoodle has found a type of grid-tie power inverter that is relatively inexpensive and will work really well.
Should be pretty easy to wire it to your home and produce electricity to lower your electric bill. I’ve studied the user manuals in depth.
My friend at work made his own Stirling engine out of stuff from around the apartment. What’s a Stirling engine? It creates motion out of heat. This one is powered by a candle flame.
The older one:
Here is his new one:
A partial eclipse will be visible to most of Asia during sunrise Monday morning, then later Sunday evening it will be visible in the western half of North America during sunset. (Now I realize how confusing crossing the International Date Line can be)
The moon can be seen directly in front of the sun first from the southeast edge of China, then Japan, at its greatest at the International Date Line in the Pacific Ocean just south of the island chain stretching from Alaska, across the southwest corner of Oregon, northern California, the middle half of Nevada, southwest Utah, northern Arizona, northwest to southeast New Mexico, and right at sunset, the southern part of the Texas panhandle.
From Austin, Texas, you can observe the partial eclipse from 7:34pm until sunset at 8:21pm.
See this Google map for the best time to observe this eclipse from the location you will be in that day. Note that all times are in universal time (GMT).

It will be visible from pretty much all of the North America continent. Look for it shortly before sunset, particularly the southern United States and Mexico.

It’s the day I turn 50 years old. Might be the end of the world. (probably not) although exactly 7 years later on 4/13/2036, Apophis will be return and will get even closer than it did on 4/13/2029.
