What is a Harvest Moon You Ask? “On average, the moon rises about 50 minutes later each day. But when a full moon happens close to an autumn equinox, the moon rises closer to the time of sunset. For mid-temperate latitudes, it rises only about 30 to 35 minutes later daily for several days before and after the full Harvest moon”. –earthsky.org
For higher northern latitudes, there is usually less time between successive moonrises.
“The difference between 50 minutes and 35 minutes might not seem like much. But it means that, in the nights after a full Harvest Moon, you’ll see the moon ascending in the east relatively soon after sunset. The moon will rise during or near twilight on these nights, making it seem as if there are several full moons – for a few nights in a row – around the time of the Harvest Moon.”
