Lunar Eclipse for 12/20/10) 11:15 pm Denver time!
Lets see I am in Minnesota, and Denver is on Mountain Time, and Minnesota is on Central Time, so when it is 11:15 PM (23:15) it would be 01:15 AM (12/21/10). I am normally up at that time, but I doubt if I would witness the Lunar Eclipse as we have another Winter Storm coming into Minnesota about that time to drop another 6 to 9 inches of snow!
Every year the moon orbit increases at a rate of 1 inch per year. If it was not for the moon being in such close orbit to the earth, we would not exist as the earth would not have a stable rotation. In otherwise the the moon acts as a balance mechanism stabilizing the earths daily rotations. Otherwise the earth would roll as it orbits the sun, the earth would not have seasons anymore, all life earth would be hard pressed to adapt to survive. As the years pass, the moon will continue to increase its distance from earth, effecting its rotation/rate around the earth, and we will no longer have solar eclipses. The moon is also acting as a "brake" on the earth's daily rotation, with the high and low tides, slamming into the continents!
Then there is December 23rd 2012 coming up and it maybe the end of time for all of us!
I was a topographic/construction/artillery surveyor in the U.S. Army and I use the stars (and my wrist watch is always set to Greenwich Time) to determine position on the earth's surface using spherical trig, ephemeris tables, spheroid tables, and 12 place logarithms for the calculations.... to determine the latitude and longitude )of the tack that was pounded into the the wooden stake that my theodolite/tripod is placed over) to plus/minus 2 mm error (true azimuth "direction" plus/minus 1 second of angle error for True North.)
