We identify the likely optical counterpart to the LMC supersoft X-ray sourceRXJ0527.8-6954, and hence recover HV2554. This identification is based on ananalysis of approximately 4 years of optical photometry obtainedserendipitously via the MACHO project. We see a steady fading of the star ofabout 0.5 mag over the duration of the observations. Evidence is also presentedfor an orbital modulation of 0.05 mag semi-amplitude on a period of P=0.39262+/- 00015 d. Our optical observations are consistent with the suggestion thatthe X-ray decline in this system is caused by cooling after a weak shell flash.Comment: 4 pages Latex, 4 figures, to appear in MNRA
