Major Solar CME (Coronal Mass Ejection) caused a storm in Earth's magnetic field on October 24, 2011.

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.

I attribute this (and weren't there some other cool things in other countries same

day?) along with the brilliant double rainbow we had to St. Raphael's feast day.

Of course it recalls the warning at Fatima, "when you see an unknown light in the sky".
