The sky tonight. The sun sets at 6:24 PM. The Moon is a waxing gibbous, 61% lit, and sets at 1:28 AM after midnight. The next full Moon is Monday, Oct 26. 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.
