A DANGEROUS SUNSPOT: Sunspot AR3217 has a 'beta-gamma-delta' magnetic field that harbors energy for X-class solar flares. Indeed, it just unleashed one (see below). The sunspot is turning toward Earth so any flares this weekend are likely to be geoeffective. Solar flare alerts: SMS Text. SOLAR FLARE AND RADIO BLACKOUT: Earth-orbiting satellites have just detected an X1.1-class solar flare from sunspot AR3217 (Feb. 11th @ 1548 UTC). Extreme UV radiation ionized the top of Earth's atmosphere, causing a strong shortwave radio blackout over South America:  Ham radio operators, aviators, and mariners may have noticed unusual propagation effects at frequencies below 30 MHz for as much as an hour after the flare. This was an impulsive flare, intense and fast. It may not have lasted long enough to lift a CME out ofthe sun's atmosphere. Confirmation awaits fresh data from SOHO coronagraphs. Stay tuned |
