Total Lunar Eclipse 7 Oct 2014

A total lunar eclipse will occur on the next full Moon, Oct 8th. The eclipse will be visible across much of the western hemisphere, including the west coast of North America and across the Pacific. This is an excellent eclipse for observers here in Hawai’i, the entire eclipse will be visible from start to end.

Some references note that this eclipse will occur on the 8th, and so it will for much of the world. For Hawai’i this will start late on the 7th when considering the time zone correction.

The Moon will be thoroughly submerged in the umbra, the darkest part of the Earth’s shadow, with an umbral magnitude of 1.16. The Moon will not pass directly through the umbra, but rather through the northern section, thus the north pole of the Moon will remain somewhat brighter, even at maximum. The eclipse occurs at the Moon’s descending node in southern Pisces, two days after perigee (October 06 at 09:41 UT). This means that the Moon will appear 5.3% larger than it did during the April 15 eclipse (32.7 vs. 31.3 arc-minutes).

Observing a total lunar eclipse requires no special equipment, simply the desire to look up. The most useful piece of equipment will be a reclining chair or some other method of staying comfortable while watching the sky. A pair of binoculars or small telescope can provide beautiful views of the Moon during an eclipse. Photography is somewhat more challenging, but not that difficult. Focal lengths of around 1000mm will fill the field of most DSLR cameras allowing photos like that shown here.

Timing for the 7Oct2013 total lunar eclipse
The entire eclipse will be visible during the night, quite convenient for amateur and casual sky-watchers. This is an excellent eclipse to publicize and use for outreach purposes.

The final eclipse of 2014 will be a partial solar eclipse visible in late October across North America.
