St. Patrick’s Day Geomagnetic Storm, Continued:

Earth's magnetic field is still reverberating from a CME strike on March 17th that sparked the strongest geomagnetic storm of the current solar cycle. At its peak on St. Patrick's Day--make that St. Patrick's Night--the G4-class storm pushed Northern Lights across the Canadian border into more than a dozen US states including New York, Washington, Iowa, Minnesota, Michigan, Oregon, Massachusetts and even Kansas. The auroras have since retreated north, but they are still glowing, as shown in this March 18th photo from Marketa Murray of Fairbanks, Alaska:

"We just experienced St. Patrick's Day #2," says Murray. "For the second day in a row, it felt like auroras were dancing on our shoulders. The show made me cry."
More auroras are possible tonight. NOAA forecasters estimate a 60% chance of polar geomagnetic storms on March 19th as Earth exits the CME's wake.
