  5. The Night Sky Sky & Telescope Friday, March 15• Look for Arcturus, the Spring Star, very low in the east-northeast after nightfall and higher in the east later in the evening. By modern measurements Arcturus is visual magnitude –0.05, making it the fourth-brightest nighttime star. It's bested only by Sirius, Canopus, and Alpha Centauri (if you combine the light of Alpha Cen A and B, because the pair appears single to the unaided eye). Saturday, March 16• Very high after dark, Castor and Pollux point almost at the waxing gibbous Moon near them. • The Big Dipper glitters softly high in the northeast these evenings, standing on its handle. You probably know that the two stars forming the front of the Dipper's bowl (currently on top) are the Pointers; they point to Polaris, currently to their left. And, you may know that if you follow the curve of the Dipper's handle out and around by a little more than a Dipper length, you'll arc to Arcturus, rising in the east. But did you know that if you follow the Pointers backward the opposite way, you'll land in Leo? Draw a line diagonally across the Dipper's bowl from where the handle is attached, continue far on, and you'll go to Gemini. And look at the two stars forming the open top of the Dipper's bowl. Follow this line past the bowl's lip far across the sky, and you crash into Capella. Sunday, March 17 • This is the time of year when Orion declines in the southwest after dark, with his Belt roughly horizontal. When does Orion's Belt appear exactly horizontal? That depends on where you're located east-west in your time zone, and on your latitude. Can you time this event? If you're near your time zone's standard longitude, expect it around 9:15 this evening (daylight-saving time). . . more or less. Monday, March 18• The bright waxing gibbous Moon traverses the sky in company with 1st-magnitude Regulus tonight. They're only a couple of degrees apart in early evening (for North America). Watch them pull farther apart hour by hour. Tuesday, March 19• The Moon, almost full, shines in the dim hind feet of Leo. Upper right of it after dark is Regulus, about a fist and a half at arm's length away. Left of the Moon by about half that distance is Denebola, Leo's tailtip. Denebola is 0.8 magnitude dimmer than Regulus (meaning about half as bright) and it'll also be closer to the Moon's dazzling glare. Depending on the clarity of your air, Denebola may or may not be a challenge to pick out.
