The Full Hunter’s Moon may appear larger and more orange than a normal full moon due to the so-called moon illusion.
Full moons occur roughly every once a month when the Earth is positioned directly between the sun and the moon. In these instances, it is fully illuminated, appearing like a perfect circle.
The October full moon will reach its peak on Sunday, October 13, at 5:08 p.m. EDT, although it will appear full to the naked eye for about a day on either side of this date, according to The Old Farmer’s Almanac.
The moon will only be really visible after sunset, however, and it will set close to sunrise the next day. (On that date, sunset in New York, for example, occurs at around 6:20 p.m.) In fact, the night of October 13 and 14 is the only one of the month in which the moon will remain in the sky from sunrise to sunset.
This Full Hunter’s Moon is particularly intriguing because it may appear larger and more orange than a normal full moon due to the fact that it rises around sunset.
