Welcome to the University of Texas Skywatchers' Report for Monday February 12th through Sunday February 18th.

The new moon for the month of February is on Saturday the 17th.

Now that Mercury has reached its greatest elongation east, it is dropping lower and lower each night as it moves back towards conjunction with the sun. Venus, however is still rising each night since it won’t reach its greatest elongation until June. Saturn is rising at 6 p.m. and is visible all night. Jupiter is rising at 2:45 am at midweek and Mars is rising at about 5:20 a.m.

Orion the Hunter, one of the most recognizable constellations in our sky is now high in the southeast at about 7 p.m. this week. The bright star below Orion is the brightest star in our night sky, Sirius, the dog star.

This week a new spacecraft is set to launch on a mission to study the Northern Lights, also known by the Latin name, the aurora borealis. The mission is scheduled to launch on Thursday the 15th from Cape Canaveral, Florida. The spacecraft is actually a small armada of five probes that will lie on the sun-earth line.
