Today:
Even with calendar Summer now behind us, the constellation Orion barely broaches the eastern horizon by 11:00 PM. But within a month this will happen two hours earlier, as Orion re-emerges to become a central constellation in the Winter sky, and by the first of December will be fully above the horizon by around 7:40 PM.
Saturday:
In this evening’s twilight a relatively flat horizon will be needed in the southwest. It is here that the Crescent Moon will dip to the horizon, doing so in lockstep with constellation Scorpio. As night falls, Antares, “The Heart of the Scorpion,” will appear immediately to the right of the Moon. But this will be brief, as the Moon and Antares will both drop below the horizon by 10:30.
Sunday:
The waxing Crescent Moon has progressed farther left from its companion last night in Scorpio, the red star Antares, low but visible in the south-southwest near 7:30 PM. Well to Antares’ right, look for the moderately bright star, Zubenelgenubi, whose curious name means “southern claw” in Arabic. Above it shines Zubeneschamali, the “northern claw”. These are the claws of the Scorpion.
