The burst lasted for 23 minutes, almost 700 times as long as the two-second average for high energy GRBs. [2] Follow-up observations were made 32 hours after the blast using the Gamma-Ray Burst Optical/Near-Infrared Detector (GROND) on the 2.2 metre telescope at the European Southern Observatory in La Silla , Chile , allowing astronomers to ...
Either a long-duration burst in which the presence of a bright supernova is ruled out, or a short-duration burst with extremely long-lasting gamma-ray emission. GRB 080319B: z = 0.937: Swift: The most (optically) luminous event of any nature observed in the universe to date. By far the brightest optical afterglow of any gamma-ray burst. GRB 080916C
The burst saturated the Fermi Gamma-ray Space Telescope's detector, [17] which captured gamma ray photons with energies exceeding 100 GeV. [18] GRB 221009A is by far the most productive event for very high-energy photons ever witnessed by scientific instrumentation.

An electromagnetic pulse (EMP), also referred to as a transient electromagnetic disturbance (TED), is a brief burst of electromagnetic energy. The origin of an EMP can be natural or artificial, and can occur as an electromagnetic field, as an electric field, as a magnetic field, or as a conducted electric current.
GRB 080319B was a gamma-ray burst (GRB) detected by the Swift satellite at 06:12 UTC on March 19, 2008. The burst set a new record for the farthest object that was observable with the naked eye: [2] it had a peak visual apparent magnitude of 5.7 and remained visible to human eyes for approximately 30 seconds.
