MULTIPLE CMES ARE COMING: NOAA forecasters say there is a chance of G2-class geomagnetic storms on Oct. 4th when multiple CMEs might sideswipe Earth’s magnetic field. Most of the incoming CMEs were hurled into space by sunspot AR3110, which unleashed a series of strong flares (M5.9, M8.7, X1) over the weekend. During G2-class storms, naked-eye auroras can descend into the United States as low as New York and Idaho.

A BIG DANGEROUS SUNSPOT: One of the biggest sunspots in years has just rotated over the sun’s northeastern limb. AR3112 has a mixed-polarity magnetic field that harbors energy for strong X-class solar flares.
