Earth Facing X Flare and CME

Published on Dec 19, 2014 by BPEarthWatch

UPDATE. sunspot AR2242 erupted on Saturday, Dec. 20th @ 00:27 UT, producing an intense X1.8-class solar flare. This picture taken by NASA’s Solar Dynamics Observatory shows a plume of material flying away from the blast site:
Radio emissions from shock waves rippling through the sun’s atmosphere suggest that a CME is en route. However, we are still waiting for data from SOHO coronagraphs to confirm the existence and trajectory of a massive storm cloud. If a CME is coming, it will probaby take 2 to 3 days to reach Earth.
There has already been one Earth-effect: Extreme UV radiation from the flare ionized our planet’s upper atmosphere and blacked out HF radio communications over Australia and the South Pacific. Below 10 MHz, transmissions were strongly attentuated for more than two hours.
