You have a short twilight window to look for a slim crescent Moon before it slips below the horizon. (sunset timetable; Moon timetable)

• Crescent Moon: Look low in the southwest after the 6:27 PM Eastern sunset. At our mid-Atlantic reference near Allentown, Pennsylvania, the Moon sets at 7:07 PM, leaving only about 40 minutes. A clear horizon matters, and the thin crescent can be difficult against twilight (sunset timetable; Moon timetable).
• Mercury, a challenge: Today it reaches its greatest apparent separation from the Sun in the evening sky. Look low in the west only after sunset; the nearby Moon and Mercury pairing favors lower northern latitudes and places farther south, so do not expect an easy Delaware sighting (October sky guide).

• Bonus: Southern Taurids remain active, just two days past their listed October 10 maximum. After dark, give yourself a broad view overhead and treat any slow meteor as a welcome extra, not a guaranteed show (Royal Observatory; Taurid viewing guide).

Moon note: Waxing crescent; next rise is 10:27 AM Eastern tomorrow, October 13, at our reference location (Moon timetable).
