The moon will be 100% full Thursday, September 23, 2010 at 4:18 A.M. Las Vegas time.

From Western Washington University:
“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.”

Back East

Abenaki – Northeast, Maine
In the Abenaki language, the name for the September moon is “skamonkas” or “corn maker moon.”

Out West

Pueblo – Southwest, New Mexico

The Pueblo people refer to the September moon as the “moon when the corn is taken in.” No name is given for the September moon in the Pueblo language.
