Super Moon vs. Micro Moon

What is so super about tomorrow’s supermoon? Tomorrow, a full moon will occur that appears slightly larger and brighter than usual. The reason is that the Moon’s fully illuminated phase occurs within a short time from perigee – when the Moon is its closest to the Earth in its elliptical orbit. Although the precise conditions that define a supermoon vary, given one definition, tomorrow’s will be the third supermoon of the year — and the third consecutive month that a supermoon occurs. One reason supermoons are popular is because they are so easy to see — just go outside and sunset and watch an impressive full moon rise! Since perigee actually occurs today, tonight’s sunset moonrise should also be impressive. Pictured above, a supermoon from 2012 is compared to a micromoon — when a full Moon occurs near the furthest part of the Moon’s orbit — so that it appears smaller and dimmer than usual. Given many definitions, at least one supermoon occurs each year, with the next being 2015 August 30.

 Big, bright, and beautiful, a Full Moon near perigee, the closest point in its elliptical orbit around our fair planet, rose on August 10. This remarkable picture records the scene with a dreamlike quality from the east coast of the United States. The picture is actually a composite of 10 digital frames made with exposures from 1/500th second to 1 second long, preserving contrast and detail over a much wider than normal range of brightness. At a perigee distance of a mere 356,896 kilometers, August’s Full Moon was the closest, and so the largest and most super, of the three Full Moons nearest perigee in 2014 now popularly known as supermoons. But if you missed August’s super supermoon, the next not-quite-so supermoon will be September 8. Then, near the full lunar phase the Moon’s perigee will be a slightly more distant 358,387 kilometers. That’s only about 0.4 percent less super (farther and smaller) than the super supermoon.
