July’s full Buck Moon, the second full moon of summer in the Northern Hemisphere, will turn full on Wednesday (July 29). It will be the final full moon before a flurry of solar and lunar activity — notably, a total solar eclipse caused by the new moon on August 12, and a partial lunar eclipse during the following full moon on August 28. A full moon always sits opposite the sun, so the path of July's full moon mirrors the sun's path in February. Two weeks after theBuck Moon, the new moon will slide directly between Earth and the sun, causing a total solar eclipse. A deep partial solar eclipse will be visible across Europe, with a small partial solar eclipse observed over Canada and the northeastern U.S..
