GEOMAGNETIC STORM: A G2-class (Kp=6) geomagnetic storm is in progress following the arrival of an interplanetary shock wave on May 31st. The source of the shock is not known; it might have been a minor CME that left the sun without drawing attention to itself. The impact sparked auroras across many northern-tier US states. This photo, for instance, comes from Christopher Griffith in Baxter, Minnesota:
“I wasn’t expecting to see any lights, but right before the midnight it broke loose and the sky lit up,” says Griffith. “Sadly the clouds quickly filled in my little window, and the auroras were gone. Just thankful for what I got so see!” Elsewhere in the USA, auroras were sighted as far south as Colorado, Maryland, Iowa, Wisconsin, and Nebraska.
