September 13, 2021: Mercury reaches greatest elongation tonight. It is a challenge to see in the bright twilight.
Venus moves through the classic Scorpion (Libra, Scorpius, and Ophiuchus) during 46 days. Venus sets later each evening and brightens in the sky. On October 9, the moon is near Venus and Delta Scorpii. A week later, Venus passes Antares. Look for an evening half phase through a telescope near the end of October and the evening greatest elongation.
