Abstract INTEGRAL monitoring observations of the Galactic Bulge (e.g. ATels #438 and #1944) have been performed between 2009 Oct 7th 20:29 and 8th 00:11 (UTC) during which transient activity from a few known sources has been recorded with respect to an observation 6 days earlier. The transient low-mass X-ray binary and known X-ray burster GRS 1741.9-2853 (e.g. Cocchi et al. A&A 346, L45, 1999) is detected by INTEGRAL/JEM-X at an average flux of about 58 mCrab (9.3E-10 erg/cm2/s) and 25 mCrab (2.75E-10 erg/ cm2/s) in 3-10 keV and 10-25 keV, respectively.
