Abstract
EVIDENCE that the galaxy A0945 – 30 is a new extragalactic X-ray source has been found from an analysis of rotating modulation collimator (RMC)1 quick-look data collected from 53 orbits of the SAS 3 X-ray observatory during the period 26 February–2 March 1978. The exposure is approximately 7 × 106 cm2 s. The galaxy lies within the error boxes quoted for 4U0945 – 30 and 2A0946 – 310 but is not one of the previously suggested candidates. A faint star alongside the galaxy also lies in the 90% confidence X-ray source error circle (Fig. 1). The data are consistent with a point source2. The flux from the source varied by a factor of about five during the period of our observation.
