Today’s Astronomical Events – April 5th, 2015

After passing through the Earth’s shadow during yesterday’s total lunar eclipse, the Moon now appears close to the bright star Spica in the constellation of Virgo. Although best seen in the pre-dawn sky, it rises before midnight and is particularly well placed for observers in the southern hemisphere.
