Éruption Solaire de Classe X1.7

 

STRONGEST FLARE OF THE YEAR: A sunspot hiding behind the sun's northeastern limb erupted on May 13th at 02:17 UT, producing the strongest solar flare of the year so far. NASA's Solar Dynamics Observatory recorded the extreme UV flash from the X1.7-class eruption:

Coronagraphs onboard the Solar and Heliospheric Observatory (SOHO) tracked a bright CME emerging from the blast site: movie. No planets were in the line of fire. However, the CME appears to be on course to hit NASA's Epoxi and Spitzer spacecraft on May 15th.

The sunspot that produced this blast is on the farside of the sun. Soon, in a few days, it will turn toward Earth, emerging into view over the sun's eastern limb. Stay tuned for a better view and, perhaps, more flares.
