July, 2018

In the early morning hours of July 10, the Moon will rise at 3:20 am, with the red giant, Aldebaran, just 0.05 degrees behind. At 3:32 am, the Moon will pass over Aldebaran and block it from view - an occultation. Just 16 minutes later, Aldebaran will emerge from the Moon's western limb.

Morning Sky

Mars begins the month as a morning star, rising at 11 am, and E Sunrise by July 27, has reached opposition, rising at sunset and staying up all night. This is also the best time to see it through a telescope, as it is a mere 35.8 million miles from Earth. It is joined by a Full Moon that night.

Evening Sky

Early in the month, Saturn is not even four degrees above the southeast horizon at sunset, but is at 16 degrees altitude by the end. It is joined by the Moon on July 24. Jupiter is 30 degrees up in the south at sunset. It sets by 2 am early in the month and by midnight toward the end. Saturn is joined by the Moon on July 20. Mercury is at Greatest Eastern Elongation on July 12, reaching 26.4 degrees from the Sun, then making a quick exit before the month is out. Look for the Moon near Mercury on July 14, and then near Venus on July 15. Venus continues to push away from the Sun, 44 degrees by month's end.
