Caught between the sun and our Solar Dynamics Observatory… the moon. The phenomenon, called a lunar transit, was observed on July 26, 2014, from 10:57 a.m. to 11:42 a.m. EDT. This happens approximately twice a year, causing a partial solar eclipse that can only be seen from SDO’s point of view. Images of the eclipse show a crisp lunar horizon, because the moon has no atmosphere that would distort light.
