The sky now. The Moon is a waxing crescent, 25% lit, and sets at 9:04 PM. The next full Moon is Sunday, Oct 25. Look for Saturn, bright in the east-southeast.

The Orionids meteor shower is active, peaking around Oct 21: at its peak, up to about 20 meteors an hour can be seen from a dark site. Cloud is forecast to cover most of the night, so the sky will be hard to see. The day is 11 hours 7 minutes long, 3 minutes shorter than yesterday.
