Follow the Arc to the Moon

   Thursday evening March 24th the 16-day old waning gibbous Moon rises about an hour after local time for sunset. About 3o from the Moon is the blue-white star Spica in the left hand of Virgo the Harvest Maiden.

   This is also the time of year when some would look at the sky and say, “Follow the arc to Arcturus and then speed to Spica.” This sort of silly sounding phrase links the curved handle, the arc, of the Big Dipper with the reddish star Arcturus in Bootes the Herdsman, and the blue-white star Spica. The Moon, at times, is part of the lineup as it is this time.
