GRB 970228 was a gamma-ray burst (GRB) detected on February 28, 1997 at 02:58 UTC. A gamma-ray burst is a highly luminous flash of gamma rays, the most energetic form of electromagnetic radiation. Since 1993, physicists had predicted these bursts to be followed by a longer-lived afterglow at longer wavelengths, such as radio waves, x-rays, and even visible light. Until this event, GRBs had only been observed at gamma wavelengths. This was the first burst for which an afterglow was observed. The burst had multiple peaks in its light curve and lasted approximately 80 seconds. Peculiarities in the light curve of GRB 970228 suggested that a supernova may have occurred as well. The position of the burst coincided with a galaxy about 8.1 billion light-years from Earth, providing early evidence that GRBs occur well beyond the Milky Way
