5. The Night Sky Monday, April 1 · The red carbon stars U and V Hydrae, and the Ghost of Jupiter planetary nebula (magnitude 7.7), all reside within a few degrees of each other in central Hydra. See Gary Seronik's Binocular Highlight column and chart in the AprilSky & Telescope, page 45 (and for more on the Ghost of Jupiter, page 56).AprilSky & Telescope Tuesday, April 2 · As spring advances, wintry Orion tilts farther over as it declines in the west-southwest after dark. Orion's Belt in its middle is almost horizontal. Orion is brightly framed between Jupiter on its right and Sirius on its left. · Last-quarter Moon tonight (exact at 12:37 a.m. Wednesday morning EDT). Wednesday, April 3 · Jupiter's moon Io crosses Jupiter's face from 7:56 to 10:08 p.m. EDT, followed by its tiny black shadow (much more visible) from 9:03 to 11:15 p.m. EDT. Thursday, April 4 · This evening Comet PanSTARRS, fading every day, is passing 2° west (lower right) of the Andromeda Galaxy, M31. They may appear about equally dim low in the northwest just as twilight is ending, for observers at fairly high northern latitudes. Think photo opportunity.Comet PanSTARRS Friday, April 5 · The huge, bright Winter Hexagon is still in view after dark, filling the sky to the southwest and west. Start at bright Sirius in the southwest. It marks the Hexagon's lower left corner. High above Sirius is Procyon. From there, look upper right to Pollux and Castor, lower right from Castor to Menkalinen and Capella, lower left to Aldebaran (with brighter Jupiter hogging the limelight near it!), lower left to Rigel at the bottom of Orion, and back to Sirius.
