Geomagnetic Storms

Geomagnetic storm warning for March 23

NOAA forecasters say that moderate G2-class geomagnetic storms are possible on March 23 when a coronal mass ejection (CME) is expected to hit Earth's magnetic field

SpaceWeather reports the solar storm cloud was hurled in our direction by an explosion in the magnetic canopy of sunspot AR2736 on March 20. During G2-class storms, auroras may be seen in northern-tier US states as far south as New York and Idaho.

AR2736 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-class solar flares.
