What the Harvest Moon means
Harvest Moon is defined by the equinox rather than by a fixed calendar month. It is the full Moon closest to the September equinox, so some years place it in October and leave September's full Moon with another seasonal label such as Corn Moon.
Around this part of the year, successive evening moonrises can be unusually close together in time at northern latitudes.
Harvest Moon and Hunter's Moon follow the September equinox, not the calendar month, so they can fall in September, October or November. Harvest Moon dates and why it rises early.
Watching it from the UK. Compare moonrise on consecutive evenings and look for the shallow angle of the Moon's path to the eastern horizon. A low Moon can look larger or warmer because of perspective and the atmosphere, not because its phase changed.
Moon names come from almanac traditions and differ between sources; the seasons are northern-hemisphere ones. NASA's Moon phase guide.
