Thunder Moon


July's full moon is traditionally called a Thunder Moon because of the summer storms that occur in this month. It is also called a Buck Moon as male deer grow new antlers in early summer. 

This full moon was also a partial penumbral eclipse. This kind of eclipse occurs when the Moon, Earth, and the Sun are not perfectly aligned. In this case, the moon passes through the more diffuse outer shadow of Earth called the penumbra. The resultant moon is marginally less illuminated than the regular full moon.
