NASA: Strong solar flare activity ongoing

Active region 1158 let loose with an X2.2 flare late on February 15, the 
largest flare since Dec. 2006 and the biggest flare so far in Solar Cycle 24. 
Active Region 1158 is in the southern hemisphere, which has been lagging the 
north in activity but now leads in big flares! Here is a blowup of the flaring 
region taken by NASA's Solar Dynamics Observatory in the extreme ultraviolet 
wavelength of 193 Angstroms. Much of the vertical line in the image is caused 
by the bright flash overwhelming the SDO imager. Credit: NASA/SDO
