Here is the video of the Magnetic Field as it was being hit by the Flare/CME.
This is from Spaceweather about the Geomagnetic Storm on Oct. 24th 2011.
Indeed, the display spread all the                                way down to Arkansas. "When I saw the alert,                                I ran outside and immediately saw red                                auroras," reports Brian Emfinger from the                                city of Ozark. "Within a few minutes the auroras                                went crazy! Unbelievable!"
Auroras were seen or photographed                                in more than half of all US states including Alabama,                                Wisconsin,                                New                                Mexico, Tennessee,                                Missouri,                                Illinois,                                Nebraska,                                Kentucky,                                North                                Carolina, Indiana,                                Oklahoma,                                Kansas,                                Iowa,                                Maryland,                                New                                York, Montana,                                Ohio,                                Colorado,                                Pennsylvania,                                Washington,                                Minnesota, Maine, Michigan, Oregon, Arkansas and                                California. Many observers, especially in the deep                                south, commented on the pure red color of the lights                                they saw. These rare all-red                                auroras sometimes appear during intense geomagnetic                                storms. They occur some 300 to 500 km above Earth's                                surface and are not yet fully understood.
