Bright Moon Covers Antares (overnight)

When the still very full moon rises over the southeastern horizon in mid-evening on Tuesday, May 13, it will be positioned very close to the very bright, reddish star Antares, which marks the heart of Scorpius. As the duo crosses the sky all night long, the rotation of the sky will shift the moon to Antares’ lower left. Meanwhile, observers in a zone extending from easternmost Polynesia, east across southern South America and the tip of Antarctic Peninsula and over to the South Atlantic can watch the moon cross in front of (or occult) Antares. Lunar occultations are safe to watch with eyes, binoculars, and telescopes. Use an app like Starry Night or Sky Safari to look up the timings where you live.
