  IIPeg is an ideal target to study stellar activity and flares, since intense
and long lasting flares have been frequently detected from this system at all
wavelengths. We report here about a BeppoSAX observation of IIPeg. We followed
the system for ~19 hours on December 5 and 6 1997 with BeppoSAX and the X-ray
light curve resembles the typical behavior of a decay phase of a long-lasting
flare. The spectral analysis shows that the IIPeg X-ray spectrum is described
by a two-temperature components, with the two dominant temperatures centered in
the range of 9-11 and 24-26 MK. The derived coronal metal abundance is low
Z~0.2 Zo compared to recent determinations of the photospheric abundance (Z~0.6
Zo). Some possible explanations for this phenomenology are reviewed. As for
most other stellar coronal sources observed with BeppoSAX, we find that in
order to fit the BeppoSAX spectra an interstellar column density about a factor
ten higher than previously determined is required.
