Aurora borealis above Lake Harriet in Minneapolis, MN: The white streak visible in the lower right of the timed exposure is an aircraft taking off from the Minneapolis-St. Paul airport.Courtesy Mark RyanOld Sol could be stirring up the atmosphere this evening with a display of northern lights (aurora borealis). Scientists have recorded a significant burst of plasma shooting from the Sun’s surface that could mean we earthlings are in for a light show tonight or early Wednesday morning. The solar wind particles are headed right toward us, and when they reach the Earth’s magnetic field they’ll interact with atoms of nitrogen and oxygen in the atmosphere and - hopefully - produce glowing sheets and fingers of green, red, blue, or even yellow in a wonderful display in the northern skies. The southern hemisphere experiences the same phenomenon but down there it’s known as the aurora australis (southern lights).
Lately, here in the Twin Cities, the air has been supersaturated with humidity so I don’t know how crisp a view we’ll get but it could be worth stepping outside tonight to see what’s up.

Solar flares
that is so beutiful
THATS SO BEUTIFUL
UPDATE: A radio report I heard on the way home from the museum this afternoon said tonight's expected northern lights display from the Sun's recent CME (coronal mass ejection) has been pushed back until early tomorrow (Wednesday, Aug. 4). This report at Boston.com seems to confirm the delay. The plasma from the solar flare is traveling toward Earth at something like one million miles an hour and is now estimated to hit our atmosphere in four waves between 3 a.m Wednesday and 2 a.m Thursday. That's okay with me since it's overcast in Minneapolis tonight, and an approaching cold front should help clear and freshen our muggy air for viewing.
Did anyone see the wave this morning?
I was asleep, but I hope to get out there tonight to see what's cookin'.
wat time is it gonna be at the sky
