According to SpaceWeather: “Fast-growing active region 1161 erupted this morning, producing an M6.6-class solar flare at 1011 UT. The almost-X category blast was one of the strongest flares in years and continued the week-long trend of high solar activity.” Just how awesome is that? Then take a look at these white light solar images done by John Chumack…

While today’s activity isn’t supposed to impact Earth in a negative manner, who knows what it might produce in the days ahead? Just ask NOAA!

“A G1 (minor) geomagnetic storm continues. What might have been three hits of shocks/CMEs seems to have merged to be just one interplanetary shock/CME structure. Look for about another day’s worth of geomagnetic activity, pending additional treats in the solar wind. Elsewhere Region 1158 had another R2 (moderate) radio blackout, and fast-growing new Region 1162 likely generated an R1 (minor) event.”

Sunspot 1158 on 02-17-11 by John Chumack

With 1158 nearing the limb and wonderfully active, now is the time for solar observers to try and catch the “Wilson Effect” – an effect in which the penumbra of a sunspot appears narrower in the direction toward the Sun’s center.

While you’re at it, it doesn’t hurt to keep watch for auroral activity tonight and in the days ahead – despite the lunar interference. With satellite communications impacted in my area, I’m anxious to see what the nights – and days – bring!

Many thanks to John Chumack of Galactic Images for sharing!
