New sunspot AR1882 isn't very big, but it is potent. The active region has already unleashed two strong solar flares today: An X1 at 08:01 UT followed by an X2 at 15:07 UT.
2-FLARE BLASTS EARTH'S IONOSPHERE: Electromagnetic radiation from today's X2-class solar flare had a significant effect on Earth's upper atmosphere. As a wave of ionization swept across the dayside of the planet, the normal propagation of shortwave radio signals was scrambled. In Alachua, Florida, electrical engineer Wes Greenman recorded the effects using his own shortwave radio telescope.
GLOBAL ERUPTION ON OCT 25TH: Solar activity is high and intensifying. New sunspot AR1882, which rotated over the sun's eastern limb earlier today, promptly unleashed an X1-class solar flare, adding to a series of lesser flares already underway from sunspots AR1875 and AR1877. NASA's Solar Dynamics Observatory recorded a bright flash of extreme UV radiation from the X1 flare, which peaked at 08:01 UT on Oct. 25th:
Astronomers classify solar flares into three categories — C, M and X — with C being the weakest and X the strongest. When aimed directly at Earth, X-class sun eruptions can interfere with satellite-based communications and navigation systems and also endanger astronauts in orbit.
That does not appear to be the case with today's X-class flares, according to an SWPC update, though officials are awaiting additional imagery of the events to see if they were associated with a massive explosion of super-hot plasma — known as a coronal mass ejection, or CME — that can hurl solar material into space at more than 1 million mph.

Hopefully they will be absorbed... with limited physical activities related. Thanks for the update cheesy
"We found that when this massive cloud of plasma strikes the moon, it acts like a sandblaster and easily removes volatile material from the surface," said William Farrell, DREAM team lead at NASA Goddard. "The model predicts 100 to 200 tons of lunar material – the equivalent of 10 dump truck loads – could be stripped off the lunar surface during the typical 2-day passage of a CME."
