X-Rays: Bursts
Scientific paper
We present X-ray and optical observations of the COMPTEL and IPN error box of the gamma-ray burst GRB 910601. Our data consists of a 20 ks PSPC ROSAT image and optical CCD images and spectra. Thirty X-ray sources were identified within the COMPTEL error box. B and V photometry of objects within the error boxes of the 12 strongest X-ray sources is presented as well as optical spectroscopy of several of the brightest optical sources. Two X-ray sources (#29 and #30) are located within the COMPTEL 1.5- error box and are also within a few arcmin of the IPN error annulus for this burst. Source #29 was the strongest X-ray source in the two-degree diameter ROSAT field. We have associated this source with the star SAO 70303, an early G-type star. A fainter star with unusual colors is located about 16" to the NE of SAO 70303. No obvious optical counterpart was found within the ROSAT error circle for #30 to V <= 22.
