LONG-DURATION SOLAR FLARE: Growing sunspot AR3032 exploded on June 13th (0407 UT), producing an M3-class solar flare that lasted more than 3 hours. NASA's Solar Dynamics Observatory recorded the slow-motion blast.

Extreme ultraviolet radiation from the flare caused a shortwave radio blackout over Japan and southeast Asia, affecting frequencies below 30 MHz: blackout map. Also, the explosion probably hurled a CME into space. The US Air Force detected a Type II solar radio burst, which is usually caused by shock waves in the leading edge of a CME. Confirmation awaits fresh data from SOHO coronagraphs.

CHANCE OF STORMS THIS WEEK: A CME launched by yesterday's slow-motion solar flare (described below) is expected to pass near Earth on June 15th. Geomagnetic storms are possible if the CME makes contact. NOAA forecasters say minor G1-class storms are likely, with a chance for G2 (moderate) and a slight chance of G3 (strong) storms.

CHANCE OF FLARES TODAY: NOAA forecasters say there is a 30% chance of M-class solar flares today. The most likely source would be sunspot AR3031, which has an unstable 'beta-gamma' magnetic field. The sunspot is facing Earth, so any flares it produces will be geoeffective.

THE SOLAR WIND IS HERE: A stream of solar wind flowing ~600 km/s from a hole in the sun's atmosphere is buffeting Earth's magnetosphere today. NOAA forecasters say there is a slight chance of G1-class geomagnetic storms while Earth is inside the stream.
