Rare full moon to illuminate night sky on Friday the 13th

The appearance of a Full Moon on the unlucky date of Friday the 13th only happens once every 20 years.

A rare Harvest Moon will appear in the night sky on Friday, September 13th. Those who live in the Eastern Time Zone will see the moon reach its full phase after midnight at 12:33 a.m. on Saturday. Those in the central, mountain or pacific time zones will be able to see the full moon before midnight on September 13.

So while keeping an eye out for werewolves, goblins and ghosts, check out the full moon!

According to the Farmer's Almanac, we haven't seen a combination like this since October 13th, 2000 and it won't happen again until August 13th, 2049.

A Friday the 13th full moon last occurred on June 13, 2014.

Other names for the full moon of September, from Native American peoples, are the full corn moon and full barley moon, which are based on its proximity to harvest time for those two crops.

Technically, a full moon occurs at a specific moment.

The so-called "Harvest Moon", which is the full moon nearest to the autumnal equinox or the start of fall on Sept. 23, will be visible on Sept. 13 and into the early hours on Sept. 14, according to the Farmers' Almanac. But in the days leading up to the Harvest Moon, this interval shortens to around 27 minutes on average, meaning there is more light available to farmers after sunset.

When viewed from Los Angeles, the Full Moon will peak around 9.32pm PDT.

This harvest moon is also being called a "Micro Moon" because it looks smaller than usual, which will make this Harvest Moon slightly less bright than average, according to Forbes. That's more than 30,000 farther "out" than the closest point in the Moon's orbit, the perigee.
