Harvest moon

The harvest moon is generally associated with the northern hemisphere and is the full moon that rises within two weeks of the autumnal equinox, 22 or 23 September, and appears within the time frame 7 September until 8 October. Therefore, an October harvest moon is rarer than a September one. It is usually one of the brightest moons of the year. It rises for several nights at almost the same time at points successively further north along the eastern horizon.
