The sky now. The Moon is a waxing crescent, 25% lit, and stays below the horizon until dawn. The next full Moon is Monday, Oct 26. Look for Saturn, bright in the 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 13 minutes long, 3 minutes shorter than yesterday.
