See the harvest moon shine in the night sky tonight, 2 days before the autumnal equinox
As the fall season approaches and colder temperatures set in, there's a silver lining to look up to literally as the harvest moon makes its debut on September 20, bringing plenty of bright moonlight.
The full moon known as the harvest moon, as it traditionally gave farmers more time to harvest their summer-grown crops into the night, will make its appearance Monday night soon after sunset.
Appearing two days before the autumnal equinox this year, the full moon can first be seen at 7:55 p.m. ET, 17 minutes after sunset, according to NASA.
During the few days surrounding the harvest moon's appearance, the moonrise will occur within just 25 to 30 minutes across the northern United States and only 10 to 20 minutes in farther north Canada and Europe, according to NASA.
Typically, the moon rises around sunset and about 50 minutes later each day, according to EarthSky. But when a full moon occurs near an autumn equinox, like the harvest moon, the moon rises closer to the time of sunset, creating a dusk-till-dawn moonlight for several nights in a row.
This year's harvest moon will be the last of the summer season for those living in the Northern Hemisphere, while for those in the Southern Hemisphere it will be the fourth winter full moon, according to EarthSky.
The harvest moon may seem bigger and brighter than other full moons, and that's because this moon is physically closer to the horizon. The location of this moon gives the illusion of largeness, despite not being any bigger than other full moons.
