  The discovery of deep spectral features in the X-ray spectrum of
1E1207.4-5209 has pushed this Isolated Neutron Star (INS) out of the chorus
line, since no other INS has shown significant features in its X-ray continuum.
On August 2002, XMM-Newton devoted a two-orbit TOO observation to this target
with the aim to better understand the nature of such spectral features, using
much improved statistics. Indeed, the 260 ksec observation yielded 360,000
photons from 1E1207.4-5209, allowing for a very sensitive study of the temporal
and spectral behaviour of this object.
