Today’s Spaceweather: cloudy with a chance of solar flare sideswipes

“Earth-orbiting satellites detected the biggest solar flare in more than 3 years. NASA’s Solar Dynamics Observatory recorded this extreme-ultraviolet movie of the M4.4 category blast. A CME launched by yesterday’s M4.4-class solar flare might sideswipe Earth’s magnetic field on Dec. 1-2, according to NOAA analysts. The glancing blow, if it occurs, is expected to cause no more than minor G1-class geomagnetic storms with auroras over high-northern latitudes.”
