ROSAT Detection and High-Precision Localization of X-Ray Sources in the 1978 November 19 Gamma-Ray Burst Error Box

We report on observations of the 1978 November 19 gamma-ray burst source, performed with the ROSAT X-ray HRI experiment. Two sources were detected, one of which is possibly variable. The latter source is identical to the source discovered in 1981 by the Einstein satellite and recently detected by ASCA. The precise localization of these sources is given, and our data are compared with optical, radio, and previous X-ray data.
