INTEGRAL hard X-ray observation of V0332+53
Abstract
The steadily brightening pulsar V0332+53 (Remillard et al. 2004 ATEL #371) was in the INTEGRAL field of view (FoV) for 2.2 ksec during a routine Galactic Plane Scan observation starting on Dec. 26, 2004 at 12:48:30 UT. The source was located at the border of the IBIS FoV (13.4 deg from the center) and thus could not be seen by the JEM-X instrument. The IBIS/ISGRI spectral analysis as compared to a recent Crab observation in a similar off-axis position gives fluxes of 1.0, 0.33 and 0.05 Crab in the 21-36, 36-58 and 60-200 keV bands, respectively.
