[2] GRB 980425 was first detected by the Gamma-Ray Burst Monitor onboard BeppoSAX on 25 April 1998 at 21:49 UTC.

The burst lasted approximately 30 seconds and had a single peak in its light curve.

[3] The Narrow Field Instruments (NFIs) onboard BeppoSAX began making observations of the region approximately 10 hours after the burst was detected.

[4] In the days that followed the burst, a variable object was detected in the original BeppoSAX error box that was not coincident with either of the two X-ray sources.

[5] A search for the burst's radio afterglow resulted in one object that was coincident with the previously discovered supernova candidate, giving early credence to the idea that SN 1998bw and GRB 980425 were related.
