Abstract
We present a first INTEGRAL observation of the 42 s transient X-ray pulsar EXO 2030+375 with IBIS/ISGRI. The source was detected during Cyg X-1 observations in December 2002. We analyzed observations during the outburst period from 9 to 21 December 2002 with a total exposure time of ~770 kilosec. EXO 2030+375 was almost always detected during single ~30 min exposures in the 18-45 energy bands. The source light curve shows the characteristic outburst shape observed in this source.


Key words: gamma rays: observations -- X-rays: individual: EXO 2030+375 -- telescopes: INTEGRAL: IBIS
