Welcome to the University of Texas Skywatchers Report for Monday April 9th through Sunday April 15th.

The moon is at third quarter on Friday April 13th so we will have a waning gibbous moon for most of the week and a waning crescent moon on the weekend.

Jupiter is the lower and fainter of the two bright objects in the west after sunset and is now setting at 9:40 p.m. Venus is the higher and brighter and is setting at 11:35 p.m. at midweek. Mars is now high in the east-southeast at sunset and is setting at 5:05 a.m. at midweek. Saturn is rising at 8 p.m. this week and it will be at opposition on Sunday so it will rise at sunset and be visible all night long.

April 12th marks the annual Yuri's Night worldwide celebration of cosmonaut Yuri Gagarin's first human spaceflight in 1961. Check yurisnight.net for a list of events. The 12th is also the anniversary of the first space shuttle mission in 1981 when John Young and Robert Crippen piloted Columbia for a three-day mission. You can learn more about the mission and others at the NASA History Program Office's website at history.nasa.gov

Public viewing at the 9 inch refractor at Painter Hall is on Friday and Saturday night now from 8:30 to 10:30 p.m. Painter Hall is located on 24th street about halfway between Speedway and Guadalupe and is northeast of the UT Tower.
