It began when a seemingly minor solar wind stream hit Earth’s magnetic field. Then whoosh! The minor hit turned into a not-so-minor display when a crack opened in the earth’s magnetic field, allowing the solar wind to pour through the breach and fuel the storm.
22 Jul 09 – Northern Lights (the Aurora Borealis) lit up the skies as far south as the Dakotas, Montana, Iowa and Wisconsin. Although the solar wind is still blowing, the crack has closed, bringing an end to the lights.
“I was up all night on July 21st, but it was totally worth it!” says photographer Zoltan Kenwell of Chip Lake, Alberta.
“It was a very impressive show that lasted 4.5 hours!” says Kenwell.
