3rd X Flare in 24 Hours - 40% Chance of More

When the action began on May 13th, the instigating sunspot (just numbered "AR1748") was hidden behind the sun's eastern limb, but now solar rotation is bringing the active region into view. [pic]

The next 24 to 48 hours should reveal much about the sunspot, including its size, magnetic complexity, and potential for future flares.

NOAA forecasters say the probability for more X flares is 40%.
