Query: First results on the HMXRB Pulsar SAXJ2103.5+4545 with INTEGRAL   We report on the preliminary timing and spectral analysis of the High Mass
X-ray Binary Pulsar SAXJ2103.5+4545 as observed with INTEGRAL during the
Galactic Pla n Scan of the Core Program. The source shows a hard spectrum,
being detected up to 100 keV. The timing analysis performed on IBIS/ISGRI data
shows evidence for a spin-up wi th respect to previous observations, performed
in 1997 and 1999 with BeppoSAX an d RossiXTE.
