Description
On March 7 2012 two bright X-class flares originating from the active region
NOAA AR 11429 erupted within an hour of each other, marking one of the most
active days of Solar Cycle 24. The Large Area Telescope (LAT) onboard
the Fermi observatory observed both the impulsive and the long duration phases
of these two bright flares detecting gamma-rays up to 4 GeV and
> 100 MeV emission for approximately 20 hours. Thanks to the increased
sensitivity of the LAT we were able to accurately localize the high-energy
gamma-ray emission to the same active region from which the X-ray emissions
associated with these flares originated. In this presentation I will discuss the
Fermi LAT detections of these bright solar flares and its implications on the
emission processes tied to these explosive phenomena.
