Summer is advancing to its conclusion, and nights continue to lengthen. Roughly thirty minutes after sunset in the west, look for “evening star” Venus above Spica, and Mercury is barely visible. The Autumn Star Fomalhaut is now visible below Jupiter by about 10 PM in the southeast. Look for Vega, which is overhead, and the twinkling Arcturus in the western evening sky. These are the two brightest stars in September. The moon is new on Monday. By the conclusion of the week, the moon will be a lovely crescent.
