Spaceweather.com reports today's event on the Sun:
MAJOR X-CLASS SOLAR FLARE: Earth orbiting satellites have just detected an X1-class solar flare from Earth-facing sunspot AR2887. The blast at 1535 UT on Oct. 28th created a massive tsunami of plasma in the sun's atmosphere:
The blast also hurled a CME toward Earth. Coronagraph images are not yet available, but evidence for a CME is already pursuasive. The USAF reports strong Type II and Type IV radio emissions generated by a CME plowing through the sun's atmosphere. In addition, energetic particles accelerated at the leading edge of a CME have already reached Earth.
When will the CME itself arrive? Probably on Oct. 30th or 31st. Fresh data from SOHO coronagraphs will allow a more precise forecast. Stay tuned. Solar flare alerts: SMS Text.
