Today’s Astronomical Events – May 15th, 2015

Earthshine is visible once again on the waning crescent Moon, but for observers in the northern hemisphere it’ll be a challenging sight. Early risers may be able to glimpse the Moon close to the pre-dawn horizon, but for Australian observers the Moon will be easily visible several hours before sunrise.
