"The GBM light curve consists of an extremely bright short pulse, with the bulk of the emission during the first 2 seconds, and continued emission out to roughly 20 seconds. This event, if it is a GRB, it is extremely bright and follow-up across all wavelengths is encouraged."

"The highest-energy photon is a 72 GeV event which is observed 32.2 seconds
after the GBM trigger."

By that, I think they mean a cluster of photons , not a single photon. Whatever the case, i think the sum total of energy of this GRB might get in the TeV domain, which will make it one for the books (maybe even a candidate for a new record??)
