October 02, 2014: Complex AR2172-AR2173 at 19h01 UTC. producing an M7.3 Class Flare. Significant post-flare hot-ionized material ejected the southwest limb. A flash of UV radiation from the flare ionized the top of Earths atmosphere, briefly disturbing the normal propagation of shortwave and VLF radio signals on the dayside of Earth. Otherwise there should be few Earth-effects from this eruption. Perched on the suns western limb, the instigating sunspot group is not facing our planet and most of the explosions debris should sail wide of Earth. There is a slim chance that a CME emerging from the blast site could deliver a glancing blow to Earths magnetic field in a few days. More information about this possibility awaits the arrival of coronagraph data from SOHO and STEREO. soho.nascom.nasa.gov/data/realtime-images.html spaceweather/
