The brightening waxing Gibbous Moon will diminish the fainter stars, leaving Summer’s brightest star, Arcturus, conspicuous west-southwest, halfway up from the horizon at 9:30 PM. The orange-white beacon has expanded into a red-giant, 25 times larger than the Sun, and 100 times brighter.
Look for a W-shape pattern of stars, low in the north-northeast this evening, which forms the basis of the throne for the Queen, Cassiopeia. It is tipped on its back during the summer, gradually climbing higher each evening, so that it is completely upside-down, later this fall.
The Full “Sturgeon” Moon runs low across the southern skies. The Moon gets its name from the large fish found in the Great Lakes and other large bodies of water, which were easier to catch in August. European settlers sometimes knew this as the “Corn” Moon.
