Night before last. Nothing. Then tonight, the aurora snuck up behind us around 10 o’clock — a whisper of a glow low in the north. Within 15 minutes it evolved into single arc, then two concentric arcs. When those arcs brightened and rose in altitude, I knew rays would soon be on the way. True that. As the eastern end of the arc faded, faint, soft rays appeared above it and slowly marched to the west. Most were dim with the exception of a single, sharp-edged, bright streak (photo above) that stood above the arc for less than a minute before fading. It looked amazing!
About 11:15 p.m. CDT, the northern lights dropped back to a faint glow but by 11:45 p.m. the arc had reformed. For all I know, we may see more or better activity in the early morning hours Friday. Checking the forecast, conditions look good for minor auroras from the northern states tomorrow night. Good luck – clear skies!
