Today’s Astronomical Events – January 19th, 2015

Mars and Neptune are close together in the evening twilight, with less than half a Moon’s width between them. Depending on your local conditions, the pair should appear within the same field of view through binoculars or a low power eyepiece. Mars will appear as a red “star” fairly low in the south-west after sunset.
