This morning at 0805 UT, sunspot 1263 produced a powerful X7-class solar flare. NASA's Solar Dynamics Observatory captured the explosion's extreme ultraviolet flash. The brunt of the explosion was not Earth directed. Nevertheless, a minor proton storm is in progress around our planet, which could affect satellites in high-altitude orbits. Also, radiation from flare created waves of ionization in Earth's upper atmosphere, briefly disrupting communications at some VLF and HF radio frequencies. SOHO coronagraphs show a CME emerging from the blast site. The cloud will probably miss Earth. At this time, however, we cannot rule out a glancing blow from the flank of the CME on or about August 11th. Stay tuned for updates
