Green-glowing arcs pierced by narrow rays appear low in the northern sky from Duluth, Minn. around 9:30 p.m. March 5.  Bob King It was just a week ago that skywatchers in the northern states and Canada witnessed a pretty aurora display. NOAA's space weather forecast predicted a G1 or minor geomagnetic storm that night, and it appeared right on schedule. During that aurora, we saw arcs and a fine display of parallel rays slowly marching across the bottom of the northern sky from about 8:30 to 10 p.m. For a brief time on March 5, bright rays dappled the northern sky.
