Solar Activity Forecast: Solar activity is expected to be moderate with a chance for an isolated major flare for the next three days (17-19 February). Region 1158 is expected to produce more M-class flares and still has the potential for producing an M5 or greater x-ray event. There is a chance for isolated M-class activity from Region 1161. Geophysical Activity Forecast: The geomagnetic field is expected to be predominately quiet on day one (February 17). An increase to unsettled to active conditions, with a chance for minor storm periods is expected late on day one into day two (18 February). The increased activity is forecast due to the expected arrival of the CME associated with the X2 flare that occurred on 15/0156Z. Day three (19 February) is expected to be quiet to active as the disturbance subsides. Solar X-ray Flux
WASHINGTON (AFP) – A powerful solar eruption that has already disturbed radio communications in China could disrupt electrical power grids and satellites used on Earth in the next days, NASA said. The massive sunspot, which astronomers say is the size of Jupiter, is the strongest solar flare in four years, NASA said Wednesday. [Related: Solar flare to create light show on Earth?] The Class X flash -- the largest such category -- erupted at 0156 GMT Tuesday, according to the US space agency. "X-class flares are the most powerful of all solar events that can trigger radio blackouts and long-lasting radiation storms," disturbing telecommunications and electric grids, NASA said. NASA's Solar Dynamics Observatory saw a large coronal mass ejection (CME) associated with the flash that is blasting toward Earth at about 560 miles per second (900 kilometers per second), it said.
The calm before the storm. Three CMEs are enroute, all a part of the Radio Blackout events on February 13, 14, and 15 (UTC). The last of the three seems to be the fastest and may catch both of the forerunners about mid to late day tomorrow, February 17.
