It IS one of the closest-and energetic Gamma Ray burst and most common cause of GRBs is formation of a new black hole. And one of the jet was exceptionally narrow and pointed directly at us, so that’s why it was brighter than usual.

Some more information about this:

The burst was so bright it effectively blinded most gamma-ray instruments in space, which means they could not directly record the real intensity of the emission. U.S. scientists were able to reconstruct this information from the Fermi Telescope data. They then compared the results with those from the Russian team working on Konus data and Chinese teams analyzing observations from the GECAM-C detector on their SATech-01 satellite and instruments on their Insight-HXMT observatory. Together, they prove the burst was 70 times brighter than any yet seen.
