April 26 2012 GEOMAGNETIC STORM HD
And Solar Flares
6-hr max: B5 0919 UT Apr26
24-hr: B7 0133 UT Apr26
A mild (Kp=5) geomagnetic storm is underway. High-latitude sky watchers should be alert for auroras. The source of this activity is a high-speed solar wind stream buffeting Earth's magnetic field.
This is the third day in a row that geomagnetic storms have circled the poles. On April 23-24, auroras were spotted in more than a dozen US states including Michigan, Nebraska, Kansas, Wisconsin, North Dakota, South Dakota, Iowa, Illinois, Minnesota, and Colorado. In Anchorage, Alaska, even the midnight sun could not completely overwhelm the Northern Lights
