We present further observational data of the supersoft X-ray source RX J0527.8-6954 exhibiting a continuous decline over the past 5 yrs. With no clear trend of a concordant temperature decrease this might suggest an evolutionary scenario where the white dwarf leaves the steady burning branch and the combined effect of reduced luminosity and cooling at constant radius produces the observed effect. We also use the on-axis ROSAT HRI pointings to derive an improved X-ray position and supply a finding chart for the counterpart search.
