Inner Planets on the Move

   This past month, November, the inner planets Mercury and Venus were very visible in the early morning skies before sunrise. Both of the planets were at or near their respective western elongation. Venus was there during August and Mercury reached its western elongation on November 10th.
   What I wanted to capture was the daily change in the position of Venus as it passed the star Spica in Virgo the Harvest Maiden. Venus moves about 1.6o each day so its eastward motion should be obvious after a day or so. It was – it is!. Mercury, if you are wondering, moves about 4o each day.
   Both inner planets were somewhere around their maximum separation from the Sun – as we see it the inner planet is to the right side of the Sun, or toward the west.
   The series of pictures were taken from two locations near my house. One is from an empty lot near U.S. Highway 50 looking east. The other pictures are from somewhere along the street I live on! The first picture was taken at Legacy Park and includes the ISS orbiting over my location.
