Some daily events in the changing sky for March 4 – 12.

by Alan M. MacRobert

Friday, March 4

  • Early March is when Sirius, thebrightest star in the night sky, shines at its highest due south rightafter dark. It's the bottom point of the equilateral Winter Triangle.The triangle's other points are orange-red Betelgeuse to the upperright, and Procyon to Sirius's upper left.
  • New Moon (exact at 3:46 p.m. EST).
  • Algol is at minimum brightness, magnitude 3.4 instead of its usual 2.1,for a couple hours centered on 8:53 p.m. Eastern Standard Time.

    Saturday, March 5

  • If the sky is clear very low in the west soon after sunset, binoculars may show Mercury lower left of the verythin waxing crescent Moon, as shown here. Brighter Jupiter higher upguides the way to them. Bring binoculars. Could this be the youngestMoon you've ever seen? Determine its age from the time of new Moonlisted under Friday above.

    Sunday, March 6

  • Jupiter shines to the leftof the waxing crescent Moon in twilight, as shown here. If you're nearlatitude 40° north, the crescent is almost exactly level like a cup.

    Monday, March 7

  • The crescent Moon poses above Jupiter at dusk, as shown here.
  • Even if you haven't got a dark sky, a telescope or even binoculars willshow quite a lot — if you know what to look for. See Hugh Bartlett'sarticle "Binocular Sights for City Nights" in the March Sky & Telescope, page 58.

    Tuesday, March 8

  • The crescent Moon, thickening as it moves farther from our line of sight to the Sun, shines higher above Jupiter now at dusk.
  • Late tonight an 8th-magnitude star in Leo should be occulted (covered)by the 12th-magnitude asteroid 72 Feronia as seen from a narrow trackfrom the Florida Keys across Louisiana to Oregon. The star may beblacked out for up to 7 seconds. See map, finder charts, and more information.

    Wednesday, March 9

  • Look northeast afterdark to spot the Big Dipper, standing on its handle. Follow the curve ofthe handle on around to the lower right, by a little more than aDipper-length, to see where bright Arcturus will rise as the eveningadvances.

    Thursday, March 10

  • The Pleiades clusterglimmers above or upper right of the Moon this evening. If the Moon'sglare interferes, move the Moon behind a tree limb or roofline.

    Friday, March 11

  • Look lower left of theMoon this evening for Aldebaran, an orange giant star 65 light-yearsaway. About three times farther to the Moon's upper right shinesbrighter Capella, 42 light-years distant.

    Saturday, March 12

  • First-quarter Moon (exact at 6:45 p.m. Eastern Standard Time).
  • Daylight saving time begins at 2 a.m. Sunday morning for most of the U.S. and Canada.
