Abstract The Transient Gamma Ray Spectrometer (TGRS) is a 215 cm3 passivelycooled germanium detector designed primarily to study spectral features of gamma ray bursts. Since shortly after its launch on 1994 Nov. 1 it has been producing high-resolution spectra of GRBs and solar flares. Some of these spectra are presented here. Although it has not yet detected any line features in GRBs-none were expected so early in the mission-several bursts have been seen simultaneously by TGRS, the Konus instruments on the same spacecraft, and the BATSE instrument on Compton GRO. A comparison of the spectra obtained by these various instruments, as presented here, may resolve the question of whether line features actually exist, and if so provide detailed spectroscopy to determine their physical origin.
