“American Indians gave names to each of the full moons to keep track of the passing year. The names are associated with the entire month until the next full moon occurs. Since a lunar month averages 29 days, the dates of the moons change from year to year. Here are titles most closely associated with calendar months.” – read more from The Old Farmer’s Almanac
One of those names for the December, 2010 full Moon is in the Shoshone (Shoshone – Great Basin, Nevada, Wyoming) language; that name is: “dommo-mea'” – meaning, winter.

More Moon information, from Wikipedia:
“A lunar eclipse occurs when the moon passes behind the earth so that the earth blocks the sun’s rays from striking the moon. This can occur only when the Sun, Earth, and Moon are aligned exactly, or very closely so, with the Earth in the middle. Hence, there is always a full moon the night of a lunar eclipse. The type and length of an eclipse depend upon the Moon’s location relative to its orbital nodes. The next total lunar eclipse will occur on December 21, 2010 at 0817 UTC.” read more from Wikipedia”
