Behemoth sunspot 1302 unleashes a strong flare on 09.24.11--an X1.9-category blast at 5:40 am EDT. NASA's Solar Dynamics Observatory (SDO) recorded the extreme ultraviolet flash in composite wavelength (211, 193, 171 angstrom). Across the top is a graph of the x-ray intensity during the flare as recorded by the GOES spacecraft. Note: The sun has been rotated 90 degrees clock-wise.
