The Case of the Missing Aurora

NASA APOD
COSMIC MESSAGE

Sometimes, near midnight, auroras suddenly stop. Nobody knows why. This nightside gap in aurora was recently confirmed by D. Chua and colleagues using data from the Ultraviolet Imager on the Polar spacecraft. The gap appears as a slight break in the auroral arc surrounding a magnetic pole. This picture shows clouds and auroras near Wildcat Mountain in Wisconsin.
