This week is an ideal time to get out and see the planets MERCURY & VENUS shortly after sunset. Venus is the higher and much brighter of the two. Mercury doesn't stray too far from the Sun so most people never see it! Look low to the horizon for Mercury.

If we get the sky to clear later tonight it looks like there is a chance for an AURORA (also known as Northern Lights). Indiana is on the southern limit of visibility. But if it clears up take a look to the Northern horizon, perhaps you may see something!
