Abstract
M. R. Sims and M. G. Watson, X-Ray Astronomy Group, University of Leicester, report that this recurrent x-ray transient (Jones et al. 1976, Astrophys. J. 210, L9) was in outburst at a flux of ~ 0.5 times the Crab (2-18 keV) when it entered the field of view of the Ariel 5 ssi on May 27. The source was still bright at ~ 0.6 times the Crab on June 6. Optical observations, particularly of Grindlay's candidate star (IAUC 3104) are urged during this x-ray outburst.
