Abstract

The Energetic Gamma Ray Experiment Telescope (EGRET) instrument detected the gamma ray bursts on June 1, 1991 (GRB 910601) and August 14, 1991 (GRB 910814)∗. Significant time structures down to 0.256 s were resolved by the anti-coincidence dome. Spectra accumulated by the NaI(Tl) crystal are consistent with a power law model with evidence of spectral evolution. Four gamma ray events within 5 degrees from the direction of GRB 910601 were found in the spark chamber, when 1.5 could be expected from the detection rate, but they arrived only after the main burst emission had decayed. When GRB 910814 arrived, the spark chamber was disabled because the earth's atmosphere was in its field of view.
