INFO FROM SIDC - RWC BELGIUM 2015 Mar 08 12:41:15

NOAA forecasters estimate a 40% to 45% chance of geomagnetic storms this weekend as a high-speed solar wind stream buffets Earth's magnetic field. Arctic sky watchers should be alert for auroras on March 8-9.

Emerging sunspot AR2297 has erupted again, producing its strongest flare yet: an M9-class explosion on March 7th at 22:22 UT.

There's more to this explosion than a solar flare. SOHO coronagraphs show a CME emerging from the blast site, as well. The cloud of plasma will probably miss Earth, but a glancing blow cannot yet be ruled out based on the limited data at hand.               

More flares are in the offing. The magnetic canopy of sunspot AR2297 has been exploding at least once a day for the past three days, and there is no reason to expect a cessation.
