5. The Night Sky Monday, March 11 · It being March, bright Sirius is highest in the south on the meridian after dark. Sirius is the closest naked-eye star that's ever visible from mid-northern latitudes (aside from the Sun). It's only 8.6 light-years away. Using binoculars, look below Sirius by almost a binocular field-of-view for a dimly glowing patch among the stars. This is the open star cluster M41, 2,200 light-years away. · New Moon (exact at 3:51 p.m. Eastern Daylight Time). Tuesday, March 12 · Look very low in the west about 30 minutes after sunset for the thin waxing crescent Moon, not much more than 24 hours old, as shown at right. As seen from North America, Comet PanSTARRS is now left of the Moon by two or three finger-widths at arm's length. It's a hazy "star" with a thin, upward pointing tail only about 1° long. Bring binoculars for a better view. And think photo opportunity! Use a long or zoomed-out lens, and put your camera on a tripod because with a long lens in twilight, exposures won't be short. Experiment with a variety of exposures. Wednesday, March 13 · Comet PanSTARRS is now below the thickening crescent Moon 30 to 45 minutes after sunset, by about a fist-width at arm's length. Thursday, March 14 · The place to look for PanSTARRS now is two fists below the crescent Moon in twilight and perhaps a bit to the right. Friday, March 15 · Look high above the Moon after dark for the Pleiades. Upper left of the Pleiades shines bright Jupiter with Aldebaran to its left, as shown here. · As soon as it gets dark now, the Big Dipper has climbed as high in the northeast as Cassiopeia has sunk in the northwest.
