Aurora Surprise: Northern Lights in the USA
Source - Space Weather News for June 1, 2013: http://spaceweather.com
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.
DID YOU MISS THE STORM? Next time get a wake-up call. Aurora and solar flare alerts are available from http://spaceweathertext.com (text) and http://spaceweatherphone.com (voice).

Great Fireball over the Western USA
Source - Space Weather News for Nov. 18, 2009: http://spaceweather.com
FIREBALLS AND METEORS: As forecasters predicted, the Leonid meteor shower peaked during the late hours of Nov. 17th, favoring sky watchers in Asia with an outburst of 100+ meteors per hour. Just as the outburst was dying down, an even bigger event took place over the western USA. Something hit Earth's atmosphere and exploded with an energy equivalent of 0.5 to 1 kiloton of TNT. Witnesses in Colorado, Utah, Idaho and elsewhere say the fireball "turned night into day" and "shook the ground" when it exploded just after midnight Mountain Standard Time. Researchers who are analyzing infrasound recordings of the blast say the fireball was not a Leonid. It was probably a small asteroid, now scattered in fragments across the countryside. Efforts are underway to measure the trajectory of the asteroid and guide meteorite recovery efforts.
