A total lunar eclipse will be visible from much of the Western Hemisphere on Tuesday, April 15, 2014, corresponding to the dreaded Tax Day in the United States. Total eclipse will last 1 hour and 18 minutes from 07:06:46 UTC to 08:24:34 UTC.

Visibility map of eclipse This eclipse will not be a central eclipse, and so one side of the moon will appear brighter than the other at all times. It is too early to make a prediction on the brightness of the eclipse, but provided that there are no major volcanic eruptions in the months preceding the eclipse, it should be relatively bright much as recent ones have been in the past decade.

This eclipse should receive significant media attention as this will be the first total lunar eclipse in almost 4 years with the previous being the total lunar eclipse of December 10, 2011. Furthermore, it will be the first to be visible in its entirety from North America since the solstice eclipse of December 21, 2010.

Weather Conditions


April is a month typically marked by severe weather including lightning, hail and tornadoes in the United States. Do not attempt to observe the eclipse is such weather is occurring in your immediate vicinity, even if the moon visible.

Photographing the Eclipse


Until the eclipse date becomes nearer and atmospheric circumstances are known, it is impossible to make an accurate prediction of the proper exposure needed for the eclipse. Assuming that there are no pollutants in the upper atmosphere, the exposure during totality should be approximately 4 seconds, at F/2.8 and ISO 100.

Keep in mind that with a fixed tripod, 4 seconds is enough to substantially blur the image so it may be necessary to use shorter exposures at correspondingly higher ISO levels then stack multiple images together to reduce the otherwise increased noise level.
