"Big sunspot AR2192 has grown even bigger, spreading across 1/3rd more solar terrain today than it did yesterday. NASA's Solar Dynamics Observatory recorded the expansion.
The chances of an explosion are growing along with the sunspot. On Oct. 20th, NOAA forecasters boosted the odds of an M-class flare to 60% and an X-flare to 20%.
Yesterday, the sunspot produced a long-duration X1-flare (movie) and a strong HF radio blackout over Asia and Australia. The next X-flare, if one occurs, will be even more geoeffective as the sunspot turns toward Earth."
Last time sunspots were this big you could see them with the naked eye (albeit at sunset, low on the horizon, don't blind yourself.)
