(Note: Times listed below are ET.)

  • Neptune, in its closest approach of the year, is in opposition on September 1. Read more about Neptune.
  • Mars, Jupiter, and Venus have crossed into the morning sky, but only Venus is easily seen at dawn, as it rapidly rises higher each morning. It hovers just to the upper right of the waning crescent Moon in the wee hours of the 10th. 
  • The autumnal equinox brings the start of autumn on the 23rd at 4:21 A.M. Saturn gets lower each evening in the southwest at dusk. Read more about the first day of fall 2015.
  • The year’s best eclipse for North American viewers unfolds on the 27th; the partial phase begins at 9:07 P.M., when the Moon enters Earth’s umbral shadow. Mid-eclipse will be seen at 10:47 P.M. See our eclipse page.
