Here’s a quick look at what’s going on in the sky during the month of September, 2013:
September 1 — Aurigid meteor shower peaks. A very favorable year for this usually minor shower.
September 1 — Equation of Time is 0.
September 5 — New Moon, 7:36 a.m. The Moon is not illuminated by direct sunlight.
September 9 — Epsilon Perseid meteor shower peaks. A very favorable year for this usually minor shower.
September 12 — First Quarter Moon, 1:08 p.m. One-half of the Moon appears illuminated by direct sunlight while the illuminated part is increasing.
September 15 — Moon at perigee (its closest point to the Earth). Because the Moon’s perigee comes so close to the New Moon, expect extremely high tides.

September 26 — Last Quarter Moon, 11:55 p.m. One-half of the Moon appears illuminated by direct sunlight while the illuminated part is decreasing.
