New Moon, August 2015
Wednesday/Thursday, Aug. 5/6, dawn. The moon is not visible on the date of New Moon because it is too close to the sun, but can be seen low in the east as a narrow crescent a morning or two before, just before sunrise. It is visible low in the west an evening or two after New Moon.
First Quarter Moon, August 2015
Saturday, Aug. 22, 3:31 p.m. EDT. The First Quarter Moon rises around noon and sets around midnight. It dominates the evening sky.
Full Moon, August 2015
Saturday, Aug. 29, 2:35 p.m. EDT. The August Full Moon is known as the Corn Moon, Sturgeon Moon, Red Moon, Green Corn Moon, or Grain Moon. It rises around sunset and sets around sunrise; this is the only night in the month when the moon is in the sky all night long. The rest of the month, the moon spends at least some time in the daytime sky.
Uranus and the Moon, August 2015
Wednesday/Thursday, Aug. 5/6, dawn. The moon will be close to Uranus just before sunrise. In southern South America, the Falkland Islands, and parts of Antarctica, the moon will actually occult Uranus.
Mercury and Jupiter Within 0.6 Degrees, August 2015
Thursday, Aug. 6, dusk. Mercury and Jupiter will pass close to each other, appearing within the same telescope field.
Mercury, Jupiter and Regulus Within 1 Degree, August 2015
Friday, Aug. 7, dusk. These three bright objects will form a tight triangular pattern low in the western sky after sunset.
Aldebaran and the Moon, August 2015
Saturday, Aug. 8, early morning. The waning crescent moon will pass close to the bright red star Aldebaran low in morning twilight. The moon will occult Aldebaran as seen from the Middle East, eastern Europe, northwestern Asia, Scandinavia, Russia, Alaska, and northwestern Canada.
Perseid Meteor Shower Peaks, August 2015
Thursday, Aug. 13, 2 a.m. The Perseid meteor shower is always the most reliable in the year, and this year benefits from having the moon out of the sky for most of the night.
Mars in the Beehive, August 2015
Thursday, Aug. 20, before dawn. Mars, just past conjunction with the sun, passes in front of the Beehive Cluster, Messier 44.
Moon Close to Perigee, August 2015
Saturday, Aug. 29, 8 p.m. local time. The moon will be closest to the Earth at 11 a.m. on Aug. 30, 222,631 miles or 358,290 km. distant. The moon will be below the horizon at that time for observers in North America. The best time to observe this “supermoon” will be just after it rises on Saturday night, Aug. 29. Those living near the ocean should expect higher tides than normal for the next few days.
