A solar wind stream hit Earth’s magnetic field on March 1st, sparking a day-long geomagnetic storm and bright auroras around the Arctic Circle.
NASA space physicist James Spann photographed the display from Poker Flat, Alaska.
This is the most obvious and accessible evidence of the connectivity that Earth has with our star the sun. Witnessing the connectivity first-hand was particularly special to me.
The storm is subsiding now, but it could start up again in response to ongoing high-speed solar wind.
