A rare 'Micro Harvest Moon' will appear this weekend

"But if you live elsewhere in the country-in the Central, Mountain, or Pacific time zones-the moment that the Moon turns full comes before midnight on Friday, the 13th".

The Moon on Saturday night into Sunday morning also will be mostly a full moon.

It's the kind of timing that makes kindergarten teachers and 911 dispatchers cringe: This week's full moon will appear on Friday the 13th.

Technically, a full moon occurs at a specific moment. The moon will be at apogee on September 13 at 9:32 a.m. EDT.

There hasn't been a Friday the 13th full moon since October 13, 2000, and it won't happen again until August 13, 2049, according to the Farmer's Almanac.

While the moon will be full early Saturday morning, Sept. 14, at around 12:33 a.m., it may be visible on Friday, Sept. 13, depending on where you live, according to NASA.

Fall begins with the fall equinox, which is still more than 3 weeks off.

What sets the Harvest Moon apart is that typically the moon rises an average of 50 minutes later each night, but the Harvest Moon rises only about 30 minutes later every day around the fall equinox, experts say. During this time, the moon rises as the sun sets - first appearing as a more dramatic, orange-colored moonlight.

"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".

Despite all those special qualities, the full moon this weekend won't be a particularly impressive site.

The opposite of a micromoon is a "supermoon" when the the moon is at perigee, or at the closest point to the Earth in its orbit. This means it will appear about 14 percent smaller, giving it the "Micro Moon" label.

The full moon in September is known as the "Harvest Moon"-a name that may have originated from ancient Native American traditions, or possibly even Anglo-Saxon or old Germanic languages".

Unless cloud cover blocks the view, the full moon is the easiest celestial event to observe.
