25. Fermi Large Area Telescope observations of high-energy gamma-ray emission from behind-the-limb solar flares

Fermi LAT >30 MeV observations of the active Sun have increased the number of detected solar flares by almost a factor of 10 with respect to previous space observations. Of particular interest are the recent detections of three solar flares whose position behind the limb was confirmed by the STEREO-B satellite. These observations sample flares from active regions originating from behind both...

Fermi LAT has observed >100 MeV emission from at least twenty-five events following impulsive flares with GOES X-ray classes from M1.5 to X5.4. The emission is consistent with pion-decay radiation produced by > 300 MeV protons. Almost all the events are associated with fast (>800 km/s) CMEs, SEPs, and impulsive hard X-ray emission >100 keV. We discuss the time profiles of the LAT events on...
