We have re-identified HV 2554 on plates of the Harvard College Observatory. Using photographic plates with higher sensitivity and spatial resolution taken within the EROS programme we do not find any variability. This suggests that a combination of variable seeing and different limiting magnitudes of the Harvard plates result in a different size of the image of the several overlapping objects and thus counterfeits a variability. Thus, HV 2554 should be discarded as counterpart candidate of the supersoft X-ray source RX J0527.8-6954.
