Multiwavelength light curves of the on-disk flare SOL2011-09-06. The Fermi LAT > 100 MeV flux points are indicated with red markers, and the GBM time profiles in the 32–76 keV energy range are in blue. The SOL2011-09-06 also had a delayed emission component, indicated by the gray points following 22:22 UT. The Sun came into the field of view at 22:11 UT, and prior to 22:19 UT, no significant detection of the flare was observed by Fermi LAT.
