- GAMMA-RAY BURSTS
- V. Schonfelder, Max-Planck-Institut fur Extraterrestriche Phy-
- sik (MPE), Garching, communicates on behalf of the COMPTEL collabor-
- ation (located at MPE; University of New Hampshire, Durham; Leiden
- Observatory; and Space Science Department, European Space Agency,
- Noordwijk): "The imaging Compton telescope COMPTEL onboard the
- Gamma-Ray Observatory has imaged cosmic gamma-ray bursts on Apr. 25,
- May 3, June 1, and Aug. 14 in its 1-sr field-of-view over the energy
- range 1-30 MeV. Using Maximum Entropy imaging techniques, direct
- mapping of these events results in the following positions accurate
- to 1 deg (listed as gamma-ray burst source indicating the date; UT;
- and galactic coordinates, l and b): GRB 910425, 0h37m48s, 229 deg,
- -20 deg; GRB 910503, 7h04m15s, 171 deg, 7 deg; GRB 910601, 19h22m16s,
- 72.5 deg, -5 deg; GRB 910814, 19h14m35s, 95 deg, -28 deg."
