Description
We present an INTEGRAL data analysis of the X-ray transient SAX J2103.5+4545 during December 2002. The source showed two type-I outbursts in this period. The INTEGRAL location agrees with the position of the recently proposed optical counterpart. A power-law model was fitted to the 10 100 keV spectrum and a photon index of 2.5±0.1 was derived. The X-ray luminosity in the 10-100 keV energy range was 3.5×1036 erg s-1 . These results indicate that the source was in a bright state. A 355-second pulse period was measured.
