A great aurora forecast tonight and tomorrow night. Minor storm levels (Kp 5) predicted. Data looks good as of this post. Not only is there a coronal hole stream (great news), but an incoming CME (also great) may swipe by earth, producing more auroras. Exciting! Now, if only the clouds would disappear. If you have clear skies in Alaska, Canada, and northern states, be ready for auroras Saturday night all the way to Monday morning.
