- Abstract
-
INTEGRAL has been monitoring the Galactic center region since the beginning of August 2012 during the Galactic bulge (GB) monitoring program (see ATel #438), the Target of Opportunity observations of Swift J174510.8-262411 (see ATel #4450), as well as during other observing programs.
During the GB monitoring observations taken on UT 2012 October 6, 16:15-21:01, the flux of the black-hole candidate 1E 1740.7-2942, also known as the Great Annihilator, was below the GB monitoring detection limits of both ISGRI (~11 mCrab, 3 sigma, 18-40 keV) and JEM-X (~6 mCrab, 3 sigma, 3-10 keV). - Link
