SOLAR FLARE AND RADIO BLACKOUT: Today, Sept. 28th at 1458 UT, a strong M7-class solar flare erupted in the magnetic canopy of sunspot AR2422. Extreme UV radiation from the flare ionized the top of Earth’s atmosphere and caused a brief low-frequency radio blackout over South America and the Atlantic ocean.

The flare itself was rather impulsive and a noteworthy coronal mass ejection (CME) does not appear evident.

AR2422 has an unstable ‘beta-gamma-delta’ magnetic field that could erupt again at any moment. NOAA forecasters estimate a 40% chance of additional M-class solar flares and a 5% chance of X-flares during the next 24 hours.
