STRONG GEOMAGNETIC STORM IN PROGRESS

 A strong (Kp=7) geomagnetic storm is in progress on June 28-29 as Earth passes through a region of south-pointing magnetism in the solar wind. The storm has sparked Northern Lights photographed in the USA as far south as Kansas. Christian Begeman sends this picture from a farm outside Hartford, South Dakota:

 

 "A clear sky allowed me to the Northern Lights dancing in southeast South Dakota around the midnight hour tonight," says Begeman. "It was quite the show."

High-latitude sky watchers should remain alert for auroras in the hours ahead. Solar wind conditions continue to favor geomagnetic activity.
