The Full Moon of March, on Thursday, is the smallest Full Moon of 2015. This is due to the fact that the Moon reaches the point of lunar apogee, in its orbit around the Earth, just 10 hours earlier than the time of Full Moon.
Like the supposed “Super Moon,” some people refer to a lunar apogee Full Moon as a “Mini-Moon,” which is defined as a Full Moon occurring within 24 hours of lunar apogee. In fact, this month's “Mini-Moon” is the closest lunar apogee to a Full Moon until 2032 January 27 !
The March Full Moon occurs at 1:05 p.m. Eastern Standard Time (EST) / 18:05 Coordinated Universal Time (UTC) on Thursday, 2015 March 5. Lunar apogee, the farthest point the Moon travels away from the Earth for this month (406,384 kilometers), comes early Thursday Morning, 2015 March 5 at 2:36 a.m. EST / 7:36 UTC (the time of this blog post). Lunar apogees can range from 404,000 to 406,700 kilometers.
Consequently, at this time, sharp viewers may notice that the Moon looks slightly smaller than how it normally appears in the sky. The Moon will then be about 30,000 miles farther away from the Earth than it would be during a lunar perigee Full Moon, when the Full Moon is closest to the Earth in its orbit.
The Moon reaches its most distant point from the Earth for 2015 on September 14 (406,464 kilometers); at that time the Moon is near the New Moon phase. The Moon reaches its closest point to Earth, during the Full Moon phase this year, at the time of the Harvest Moon on September 28.
The rising outdoor temperatures, as the days approach the Vernal Equinox, the official beginning of Spring on March 20, leads to the thawing of the ground and the appearance of earthworms, followed soon by robins. Hence, the Full Moon of March is known as the Worm Moon.
However, Native Americans also had other names for the March Full Moon. With the increased cawing of crows, northern tribes knew the March Full Moon as the Crow Moon. They also called it the Snow Crust Moon, for the increased crusting of snow, caused by the thawing of snow by day and the freezing of the water by night.
The Abenaki tribe (New England and adjacent areas of Canada) called the March Full Moon “Mozokas” or the Moose Hunter Moon. The Creek nation, located further south, called it the “Tasahcusee” or Little Spring Moon. And, the Dakota Sioux actually called it the “Moon When Eyes Are Sore From Bright Snow.”
Colonial Americans called the March Full Moon the Sap Moon, for the time when maple trees were tapped. They also called it the Lenten Moon, as it was the last Full Moon of Winter usually occurring during the Christian period of Lent.
Full Moon names for March, in the Southern Hemisphere, include Harvest Moon and Corn Moon. However, this year the March Full Moon is not the Harvest Moon in the Southern Hemisphere. The Full Moon that will occur on April 4 will actually be the 2015 Harvest Moon for the Southern Hemispere, as it will be just slightly closer to the March 20 Vernal Equinox than this month's Full Moon.
