Full Moon for September

Your rating: None Average: 4.1 of 5 (138 votes)

The Full Moon for September 2015 is a big event! It brings the nearest Supermoon of the year and a total lunar eclipse! 

Best Supermoon of Year

August 27 brings a "perigee" full Moon—which means the day the Full Moon rises happens to also coincide with the day when the Moon is nearest to Earth in its orbit. 

A recent popular tern for a "perigee" full Moon is a "Supermoon."  A bit catchier, perhaps?

September's Supermoon is ALSO the nearest Supermoon of the entire year. When this happens, there are some physical effects, such as elevated tides.

Total Eclipse of the Moon

Further, the year's BEST lunar eclipse for North America unfolds on the 27th! Totality begins at 10:11 P.M. (ET) and ends at 11:24 P.M. (ET). See our Eclipse page for more information.

The September Harvest Moon

Traditionally, full Moon nearest the autumnal equinox is called the Harvest Moon. During this month, the Moon helps the harvest by providing more light at the right time than other full Moons do. Learn why in our article, "Shine On, Harvest Moon."

In years when the Harvest Moon falls in October, the September full Moon is usually known as the Full Corn Moon because it traditionally corresponds with the time of harvesting corn. It is also called the Barley Moon, because it is the time to harvest and thresh the ripened barley.

Wondering what happened to

By Jeni

Wondering what happened to the moon last night September 28th 2014. Was watching it go from a very pretty bright to the yellow & then to the blood red, It was only a crest moon but it totally changed colors then disappeared so to say. Like an eclipse but it never showed back up.? Did anyone else see it last night? 9 to 10 PMT (cst) color
changing then total dark @ 10 or just after. Looked for it all way up to 1 am.

Jeni, i was wondering exactly

By bren kane

Jeni, i was wondering exactly the same thing. That's why i went on this site to see if anyone had an answer to the self same question. Lo and behold you asked the same one! Sadly no answer yet. I'm looking out now and cannot see the new moon. Any answers anyone?

By Jeni

No replies yet :( Samething tonight moon has vanished or I'm going locco. lol was out side at 9:45 pm crest moon again then back outside @ 10:45 & no moon. Even on nights with clouds in sky you can still see light from the moon but no clouds. Strange happenings.... Moon eclipses

Interesting question! The

By Almanac Staff

Interesting question! The times and time zone that you are describing suggest that the Moon was setting, which would explain its change in color and its later disappearance.

To give some details: No lunar eclipse has been forecast for this time. The new Moon was on September 24; first quarter on October 1. So, the Moon is now a waxing crescent. Although exact timing of moonrise/set will depend on your location, I've chosen Lebanon, Missouri, for an example for Central Daylight Time. So, according to the United States Naval Observatory data, for that location, on September 28, it rose at about 11:13 am CDT and set at about 9:47 pm CDT. On September 29, the Moon rose at about 12:12 pm CDT and set at about 10:36 pm CDT. So, I'm guessing from your time zone, you wouldn't see it at 10:45 (or at 10:00 September 28) because it would have then been below the horizon.

When the Moon is setting, one sees it through a thicker atmosphere. The thicker the atmosphere, the more likely the light has to travel through dust, pollution, etc., which can scatter more of the shorter wavelengths of light, leaving the longer wavelengths, such as red, to reach your eyes. This can make the Moon appear red. Smoke from fires or volcanic ash high in the atmosphere can also change the Moon's color to reddish.

Hope this helps!

I'm really surprised that no

By JennySD

I'm really surprised that no one has mentioned the fact that the harvest moon this year on October 8th will be the 2nd blood moon of the 2014-2015 lunar tetrad, with all four of the moons landing on either Passover or Sukut (sp?), both major Jewish feasts. The first one was in April this year and was gorgeous, but it doesn't seem that the United States will be able to get much of a look at this one on October 8th, as it will be setting as the sun rises, and only above the horizon for half an hour.

The 3rd one will be in very early April, 2015, and the 4th in very late September, 2015.
And just before the 2nd one, there will be a total Solar Eclipse on March 20, 2015, the day of the Spring Equinox. I'm not sure of what part of the world will see it though. I seem to maybe recall that it could be over Australia, but I'm not sure. Bummer if it is. But mark your calendars and enjoy the beautiful blood red moons!

Since a blue Moon occurs only every two or three years, a birth during this time is certainly something to celebrate! As to folklore, nothing shines through as a widespread belief, although you can find some sources online that say various things.

Hi! I also wondered what "arbor low" meant, so I looked it up. (I thought it may have been a terminology) but in actuality, it is a site! Called a henge, it is an ancient place, believed to be very spiritual. I wish I could travel to places like this. :)

By Richard Schock Sr.

In North America during a full Moon does the Moon rise or set on the Horizon at the same exact time as the Sun sets or rises on the opposite Horizon? I have been blessed to see this beautiful site a few times while driving across Lake Pontchartrain Causeway in New Orleans which runs North-South in both directions. When you get 10-13 miles out(approx. middle) and look to the left and then the right I have seen the full Moon setting on the Western Horizon as the Sun was rising on the Eastern Horizon. A very awesome and beautiful site on water..

The Full Moon rises in the

By Almanac Staff

The Full Moon rises in the part of the sky approximately opposite from where the Sun sets (since the Sun is  illuminating the full face of the Moon at this phase). However, the moonrise does not usually occur precisely at the time of sunset. Check Almanac.com for the exact time for your area:

Also, the exact moment when the Moon is completely full may not occur at moonrise (and could be off a few hours).
However, the "full" Moon will rise near sunset, and whether exactly full or not, it is indeed a lovely sight.
