I heard about this earlier today, but a pal of mine just sent me this:
Space Weather News for March 7, 2012
SOLAR ACTIVITY: Big sunspot AR1429 has unleashed another major flare–an X5-class eruption on March 7th at 00:28 UT. As a result of the blast, a radiation storm is underway and a CME will likely hit Earth’s magnetic field in a day or so. Geomagnetic storms are already in progress at high latitudes due to earlier eruptions from the active sunspot. Last night, auroras were spotted over several northern-tier US states including Michigan and Wisconsin.
The last big coronal mass ejection happened a day or so before SPAR Winter Field Day earlier this year, and as a result, most of the club guys had lousy results on the bands that day.
We’ll see what happens come Thursday.
