"High-latitude sky watchers should be alert for auroras. A strong (Kp=7) geomagnetic storm is in progress.
Earth's magnetic field has been strongly disturbed since approximately 1300 UT on Sept. 26th when a CME hit our planet. The impact strongly compressed the magnetosphere, exposing geosynchronous satellites to solar wind plasma, and ignited auroras around both poles. Gordon McLellan photographed these pastels over Lake Michigan after sunset on Sept. 26th:
