GEOMAGNETIC STORM WARNING: NOAA forecasters say there is a 75% chance of geomagnetic storms on March 23rd when a coronal mass ejection (CME) is expected to sideswipe Earth’s magnetic field. Storm levels could reach category G2, which is moderately strong. During G2-class storms, auroras may be seen in northern-tier US states as far south as New York and Idaho.
BIG CRACKLING SUNSPOT: A few days ago, sunspot AR2736 didn’t exist. Now, the rapidly-growing active region (movie) stretches across more than 100,000 km of the solar surface and contains multiple dark cores larger than Earth. Moreover, it has a complicated magnetic field that is crackling with C-classsolar flares. The sunspot is inset in this magnetic map of the sun from NASA’s Solar Dynamics Observatory.
