Thursday, August 20, 2026
Today:
The Moon is just one day past its First Quarter tonight, as it nuzzles up close to the reddish star Antares, the “heart” of the Scorpion, low in the south-southwest as twilight gives way to darkness from 8:45 PM to 9 PM. The pair will slide lower into the southwest, with the Moon setting by 11:15 PM, and Antares about 15 minutes later.
