Abstract

The recurrent X-ray transient pulsar "MXB 0656-072" (also known as XTE J0658-073, ATELs 197, 199, 200, 202, McBride et al. 2006) has begun another outburst about four years after the previous outburst in October 2003. On November 10 (MJD 54414.9, begin of Integral revolution 620) the source was first detected in ISGRI with a count rate of 6.9 +/- 0.8 counts per second between 20 and 40 keV (corresponding to 40 mCrab)
