The qualities of the harvest moon — the full moon that rises closest to the autumn equinox — include it appearing full, large and orange for several days around its appearance, which was Thursday.

During September and October evenings, the moon rises slightly sooner than average and at a narrower angle, making it appear to be dramatically fuller and more orange than usual, according to EarthSky.org. The orange glow comes from light being scattered through the Earth’s atmosphere, like during sunsets and sunrises.

This particular moon is named for its importance to farmers who may have relied on the bright moon to bring in the last of the crops.

It was celebrated in a song, “Shine On Harvest Moon” written by vaudeville team Nora Bayes and Jack Norworth and covered by scores of musicians, including Leon Redbone.
