Abstract As part of its regular monitoring of the Galactic Bulge (see ATel #438) INTEGRAL observed this region of the sky on September 13, 2011, between UTC 9:14:50 and 12:56:26. Both the JEM-X and the IBIS/ISGRI instruments detect the transient neutron star low-mass X-ray binary KS 1741-293 at the following flux levels:
JEM-X: 6 ±3 mCrab (3-10 keV) and 14 ±6 mCrab (10-25 keV)
ISGRI: 11 ±2 mCrab (18-40 keV) and 13 ±2 mCrab (40-100 keV)
We note that the activity of this source already started two weeks ago as has been reported by Linares et al.
