The Full Moon-Lick Observatory
The Harvest Moon is the full moon that occurs nearest to the autumnal equinox. The equinox took place at 11:09 pm yesterday, and the moon will be officially full at this Thursday morning at 5:17am -- this is about as close as you can get! The name "harvest moon" comes from the days before we had electricity. Farmers used the bright light of the full moon around the equinox to continue harvesting their crops.
