A huge solar flare, at least the third strongest ever recorded, hit the Earth around 1500-1600 JST today. Among the initial casualties is the Kodama data relay satellite (built by Mitsubishi Electric) and its JAXA controllers have now shut it down. (We have been told by informed sources that many Japanese-built satellites have inefficient shielding against solar radiation.) But any satellite is susceptible to getting zapped.
Shortwave radio communications have been wiped out at times in many of the high frequency bands. Electrical power grids could also be damaged.
This was an X17.2 -- in the mega flare category signalling an unprecedented event -- in which the sun in a coronal mass ejection, hurled two billion tons of plasma toward the Earth.
On the bright side, even those south of Alaska can get a good aurora show. The aurora appears to be visible in most of Canada.
