The waxing gibbous moon dominates the evening sky, but with luck we may see the aurora tonight. On October 22 the Sun cut loose with a CME or coronal mass ejection that’s expected to side-swipe the planet. A minor G1 storm is expected to start this afternoon and continue overnight. Because of the moonlight, the low northern sky will look like it’s glowing a little to start with, so watch for a distinct arc and rays of light.
We have something wonderful in store tomorrow morning. Venus and Jupiter, the two brightest planets, will be in conjunction just a 1° apart in the eastern sky at dawn. Mars, located about 3° further east, will make it a perfect trifecta. You can see them anytime between two hours and 45 minutes before sunrise. If you have a wide open view to the east, Mercury joins the scene about 45 minutes before sunup about 7° high or just under “one fist” above the eastern horizon for a “quadfecta”.
Jupiter and Venus will be nearly the same distance apart on Monday morning, too. Don’t miss the show!
