Tonight's Sky for November 16: Summer at Dusk


It's fall, but the sky still says summer if you go out early enough. Case in point: go out just as the sky is getting dark and look straight up to see the Summer Triangle, an asterism that gets its name from its shape and best season or viewing. Consisting of Vega (alpha Lyra), Deneb (alpha Cygnus), and Altair (alpha Aquila), there is no star dimmer than 1st magnitude, which makes the Triangle just about impossible to miss.
