Optical Studies of gamma-Ray Bursts. II. The Superbowl Burst GRB 930131

We report CCD observations of the central region of the COMPTEL error box for the 1993 January 31 γ-ray burst. One optical transient was found. Its distance from the IPN track and EGRET error box make the association of this object with GRB 930131 doubtful. We present new CCD observations of two objects identified by Schaefer et al. [preprint (1993)] that are located within a few arcminutes of the IPN that were reported to be possibly variable. We also report observations on the ROSAT All-Sky Survey EUV source noted by those investigators and the RS CVn star HD 106255. The ROSAT All-Sky Survey EUV source is suggested to arise from a faint, but relatively rich cluster of galaxies. HD 106255 is located approximately 7' from the IPN. Our CCD results show that this star was bluer than previously reported, but these observations were obtained significantly after the occurrence of GRB 930131. It is not possible to estimate the color of HD 106255 when the burst occurred.
