SOLAR FLARE: Sunspot AR1261 unleashed a brief but powerful solar flare on July 30th at 0209 UT. Registering M9 on the Richter Scale of Flares, the blast almost crossed the threshold into X-territory (X-class flares are the most powerful kind). NASA’s Solar Dynamics Observatory recorded the flare’s extreme ultraviolet flash:
Because of its brevity, the eruption did not hurl a substantial cloud of material toward Earth. No CME is visible in SOHO coronagraphs. The eruption was not geoeffective, although future eruptions could be as the active region continues to turn toward Earth.
