[1] It was an extremely bright burst that was successfully localized to supernova remnant N49 in the Large Magellanic Cloud.
[3] Eleven seconds later, Helios 2, a NASA probe, also in helio-orbit, was saturated by the blast of radiation.
Seconds later, Earth received the wave of radiation, where the powerful output of gamma rays inundated the detectors of three U.S. Department of Defense Vela satellites, the Soviet Prognoz 7 satellite, and the Einstein Observatory.
Because gamma rays travel at the speed of light and the exact time of the detection pulse was recorded by several distant, widely dispersed spacecraft as well as on Earth, the source of the gamma radiation could be triangulated to within an accuracy of approximately 2 arcseconds.
[5] in the Large Magellanic Cloud; the source was named SGR 0525-66, the event itself was GRB 790305b.
