Asteroid 13 Egeria is moving through the constellation Virgo this month, and today is a particularly good opportunity to try to spot its motion over just a few hours.  Shining at 10th magnitude, Egeria can be picked up with a small scope even under mild light pollution. A few hours after dark, you’ll find Virgo more than 40° high in the south. It’s a big constellation: Egeria is located in its eastern reaches, about 7° northeast of the bright star Spica. Use 6th-magnitude 80 Virginis as a signpost — Egeria is just 1.2° east of this star tonight. The asteroid is passing north of a slightly brighter 8th-magnitude field star, HD 118957 (also cataloged as HIP66706).…
