Moon Says, “I’m Your Venus.”

   Sunday March 22nd the waxing crescent Moon will be within about 3o from the inner planet Venus. Both will easily fit within the field of view of binoculars, and both will offer an interesting contrast in apparent magnitudes. Venus shines at a -4.0 while the 2.6-day old crescent Moon has an apparent magnitude of -10.0.

Mercury and Spica

20sep-ecliptic   Saturday evening the innermost planet Mercury will come within about 0.5o of the star Spica, a bluish-white star in the constellation Virgo the Harvest Maiden. While the pair is around 25o east from the setting sun the angle of the ecliptic is low compared to other days of the year.

   Viewing these two may definitely be a challenge because of how low they will be when the sky darkens enough to see them. However using binoculars or a wide field view eyepiece in a telescope they can be seen. And the contrast in apparent magnitudes is easily noticed (assuming you can see the pair). Mercury has an apparent magnitude of 0.11, while Spica has an apparent magnitude of 1.0.
