  The error box of GRB980425 has been observed by XMM-Newton in March 2002,
with the aim of measuring the late epoch X-ray emission of the supernova 1998bw
and of clarifying its supposed association with the GRB itself. We present here
the preliminary results obtained with the EPIC PN camera. Our observations
confirm the association between SN 1998bw and GRB980425. The EPIC PN
measurement of the SN 1998bw flux is significantly below the extrapolation of
the power-law temporal trend fitted to the BeppoSAX points and implies a faster
temporal decay. We propose different physical interpretations of the SN X-ray
light curve, according to whether it is produced by one or more radiation
components.
