¡Sky Watch!
by Jim Walker


       This month's star chart shows a special treat visible shortly after sunset on the evening of February 23 (sunset is at 6:49 PM).  Four of the five naked-eye planets - not counting the earth - are visible a little south of  west.  (Mars, the fifth naked-eye planet, doesn't rise until 11:38 PM, well after the other four have set.)
        The star chart shows the positions of the planets at 7:00 PM on February 23.  There is a nice conjunction of Venus and Jupiter.  These planets are so close as to be nearly superimposed at the scale of the star chart.  In fact, Venus and Jupiter are 15 arcminutes apart at this time, about half the diameter of the full moon.  Mercury sets at 7:59 PM, but you will be able to see Venus and Jupiter for nearly another hour.
        On February 13, Venus and Jupiter are about 10 degrees apart.  After their close conjunction on the 23rd, they begin diverging, and on March 5, they are again 10 deg apart.  You will have ample opportunities to watch this slow dance of the planets with your naked eyes or any pair of binoculars.  Watch the planets close with each other and then separate.
