Rare full moon to appear on Friday the 13th across the US


A full moon on Friday the 13th is approaching at the end of this week, almost.

Take note skywatchers, because this weekend a full "harvest" moon will appear in the night sky across the United States-and for some, it may even be visible on Friday 13. 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. The last time the US saw a full moon on Friday the 13 was October 13th, 2000.

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

According to the Farmer's Almanac, the moon will turn full at 12:33 a.m. on September 14 for those in the Eastern Time Zone.

In Toronto, for example, the sun is slated to set at 7:31 p.m., and the moon is expected to rise at 7:46 p.m. on Friday, according to the website Time and Date.

When does fall begin?

Technically, a full moon occurs at a specific moment. The bright light of the moon allows farmers to work a little bit later into the night to bring in their crops before fall sets in.

What makes the Harvest Moon unique is that rather than rising its normal average of 50 minutes later each day, the moon rises at almost the same time each night leading up to when it's full.

"The reason for this seasonal circumstance is that at this time of the year, the path of the Moon through the sky is as close to being along the horizon as it can get". This means it will appear about 14 percent smaller, giving it the "Micro Moon" label.

When viewed from Los Angeles, the Full Moon will peak around 9.32pm PDT. That's more than 30,000 farther "out" than the closest point in the Moon's orbit, the perigee.
