AURORA SURPRISE:  Last night, Northern Lights spilled across the Canadian border and descended into the contiguous United States as far south as Colorado and Nebraska.  The display was caused by the unexpected arrival of an interplanetary shock wave on May 31st.  Check http://spaceweather.com for pictures of the display and the odds of a repeat performance tonight.
