2019, October 26, 2019: Mars and the Moon


After its solar conjunction in early September, Mars has been crawling into the morning sky.  It is a not-so-bright “star” that is low in the eastern sky before sunrise in late October.  The moon provides guidance to its location.  Take along a binocular and find a clear horizon.  Here’s what to look for.

  • October 25: One hour before sunrise, the waning crescent moon (26.7 days past its new phase and 10% illuminated), over 20° up in the east-southeast. Mars, only 5° up in the east, is nearly 19° to the lower left of the moon. On closer inspection, the Red Planet is 3.8° to the lower right of Gamma Virginis.
  • October 26: The moon is very thin this morning, only 4% illuminated.  The thin sliver is striking to see. One hour before sunrise, the moon, about 11° up in the east, is 1.9° to the upper left of Gamma Virginis and nearly 6° to the upper left of Mars. Use a binocular to view this scene.
