As forecast, the northern lights returned last night. Instead of the typical arc, they appeared as two smoky “sausages” — one in the northeastern sky and the other in the north — about 20° above the horizon. Over several hours, the sausages pulsed in brightness like a slow-beating heart while gradually lengthening until they met around midnight in a continuous arc. Clustered pillars of light reached toward the arc from the northern horizon now and again throughout the night.
Not what you’d call a spectacular show, it was a different sort of aurora, a type less often seen. What about tonight? We have good news again! NOAA space weather experts predict a moderate storm (G2) during the early part of the evening over the eastern half of the U.S. that will grade down to a minor or G1 storm overnight.
So be sure to watch for activity starting around the end of twilight tonight or around 9 p.m. onward.
