INTEGRAL observes an increasing Hard X-ray flux of GX 339-4
Abstract
Since the beginning of 2010, GX 339-4 entered a new outburst phase (ATEL #2380, #2384). INTEGRAL observed the source between Feb. 10th and Feb. 22th, during the Galactic Bulge and the RX J1713.7-3946 programs. These observations correspond to a total of 850ks exposure time. Between February 13th and 16th, GX 339-4 displayed a steady count rate of 25-30 cts/s in the 20-40 keV ISGRI energy band (~160-200 mCrab).
