Moon Joins Mars, Saturn and Uranus in Dawn Conjunction

A pre-dawn grouping on Saturday and Sunday will let the Moon guide observers to Mars and Saturn with Uranus visible only through optics.

Overview

  • The grouping is visible the mornings of July 11 and July 12 and appears low in the eastern sky before sunrise.
  • The Moon, Mars and Saturn are bright enough to see without instruments while Uranus will usually require binoculars or a small telescope.
  • Observers should find a clear, unobstructed eastern horizon and leave city lights behind so eyes can adapt to the dark.
  • Arizona offers especially favorable views at several DarkSky sites and parks named by local guides and DarkSky International, including Flagstaff, Grand Canyon-area locations, Sedona and Saguaro National Park.
  • The event comes just before a new Moon on July 14 that will improve faint-object viewing and ahead of late-July changes in Saturn’s ring profile and the delta Aquáridas meteor peak.
