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.^[3] The magnitude was brighter than 9.0 for approximately 60 seconds.^[4] If viewed from 1 AU away, it would have had a peak apparent magnitude of −67.57 (21 quadrillion times brighter than the Sun seen from Earth). It had an absolute magnitude of −38.6,^[5] beaten by GRB 220101A with −39.4 in 2023.^[6]^[7]
