25 Sep    At dawn, Regulus is 4 finger-widths to the moon’s upper left. Less than 10 percent of the moon’s surface is illuminated.

27 Sep    New moon at 1109 UT

28 Sep    The moon is at perigee, less than 358,000 kilometers or 56.06 Earth-radii away. Perigee occurs only 14 hours after the new moon, so we can expect extreme tides.

30 Sep    Look for the head of the Scorpion to the left of the thin waxing crescent moon low in the southwest at dusk.

1 Oct    Low in the southwest at sunset, the waxing crescent moon is 2 finger-widths above Antares. The Big Dipper is far to the right above the northern horizon. The moon sets 3 hours after the sun.
