Welcome to the University of Texas Skywatchers' Report for April 18th through the 24th.

The full moon for the month of April is on Sunday the 24th. This full moon is known as the Grass Moon, the Egg Moon and the Fish Moon. The sun and moon are close to being in line with earth, as was evidenced by the solar eclipse from two weeks ago. The three objects are partially aligned, but the lunar eclipse this coming weekend will only a penumbral eclipse. In a penumbral eclipse, the moon will pass through the outermost part of the earth's shadow. An excellent animation at spaceweather.com shows the set-up and explains why this type of eclipse is particularly hard to observe.

The bright object close to the moon in the east at sundown on the 21st and 22nd is Jupiter, which is now getting high above the horizon by the end of twilight. Saturn is working it's way into the western skies by mid-evening, but still has at least a month of good evening visibility.
