  Nova LMC 1995, previously detected during 1995-1998 with ROSAT, was observed
again as a luminous supersoft X-ray source with XMM-Newton in December of 2000.
This nova offers the possibility to observe the spectrum of a hot white dwarf,
burning hydrogen in a shell and not obscured by a wind or by nebular emission
like in other supersoft X-ray sources. Notwithstanding uncertainties in the
calibration of the EPIC instruments at E<0.5 keV, using atmospheric models in
Local Thermonuclear Equilibrium we derived T(eff)=400,000-450,000 K, L(bol)=2.3
x 110(-14) 0(37) erg cm(-2) s(-1) and we verified that the C abundance is not
significantly enhanced. The RGS spectra do not show emission lines of a wind or
nebula, but the white dwarf absorption lines cannot be resolved. The upper
limit to the flux in the 0.6-10 keV range is 10(-14) erg cm(-2) s(-1). There is
no rapid or large variability in the light curve, but we find a peak at 5.25
hours in the power spectrum.
