After dark, look for Saturn, bright in the east-southeast. A planet shines with a steady light where the stars around it twinkle. 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. The bright Moon hides all but the brightest of them. The sky is forecast to stay clear: a good night to look up. The day is 11 hours 4 minutes long, 3 minutes shorter than yesterday.
