The sky tonight. The sun sets at 6:25 PM. The Moon is a waxing gibbous, 62% lit, and sets at 1:38 AM after midnight. The next full Moon is Sunday, Oct 25. 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 5 minutes long, 2 minutes shorter than yesterday.
