Abstract
We report observations which identify the optical/IR counterpart to th e ROSAT X-ray transient RX J0117.6 - 7330. The counterpart is suggeste d to be a B1-B2 star (luminosity class III-V) showing an IR excess and strong Balmer emission lines. The distance derived from reddening and systemic velocity measurements is consistent with the distance derive d from X-ray measurements and puts the source in the Small Magellanic Cloud (SMC).
