Northern lights. More technically called the “aurora borealis.” A natural light display caused by charged particles from the sun colliding with gases in Earth’s upper atmosphere. Most visible near Earther’s north magnetic pole but sometimes farther south, particularly in autumn, depending on Earths tilt. A similar phenomenon in the Southern Hemisphere is called the “aurora australis.”
A few minutes before 1 o’clock. As seen pulsing and dancing over a ridge between Winona and Wilson. An encore is expected Wednesday night, weather permitting, between 9 p.m. and midnight. Perhaps there will be curtain calls going to 3 a.m. Image: Andy Frank
