Physics & Astronomy
The COMPTEL experiment aboard the Compton Gamma-Ray Observatory is designed to image celestial gamma-radiation in the energy range from 0.7-30 MeV. With a field of view of 1 sr it is capable of locating strong point sources with an accuracy of better than 0.5 deg. From June 15 to 28, 1991 and a second time from October 3 to 17, 1991 the region containing the supernova SN 1991T was observed by COMPTEL. Here preliminary results from these observations are presented, with special attention to a search for gamma-ray line emission from the supernova.

The COMPTEL experiment aboard CGRO is designed to image celestial gamma-radiation in the energy range from 0.7-30 MeV, and also to accumulate time-resolved NaI detector spectra (0.1-10 MeV) upon receipt of a BATSE burst trigger signal. During the early phases of the GRO mission several bursts have been observed. In this paper we present time profiles and first results from spectral analysis for GRB 910425, GRB 910601, and GRB 910814.
