Abstract

We report on the first detection of the Be star HMXBs GX 304-1 and H1417-624 above 20 keV with the IBIS/ISGRI X-ray imager on board INTEGRAL. From 2008-06-24 to 2008-07-09, INTEGRAL performed monitoring observations of the Galactic plane around l=305 degrees for a total exposure time of 352 ksec. GX 304-1 was detected in all spacecraft revolutions, and shows brightening with time. H 1417-624 was detected only in revolution 699 and 700 (2008-07-04 to 2008-07-09).
