Happy Harvest Moon!
Happy Harvest Moon! It is the full moon that is nearest the start of the autumn equinox and this year that is October 5th.
It is a significant full moon because near the fall equinox the moon rises soon after sunset and thus shines bright early in the evening. This helps farmers to harvest crops in the light of the full moon.
Additionally, it appears to rise the same time each night for several nights (about 25 minutes later) while most full moons rise about 50 minutes later each night in the US and southern Canada. In more Northern areas the Harvest Moon rises only 10 - 20 minutes later each night. This is a great benefit at sunset for farmers.
