Abstract A new season of observations for the INTEGRAL Galactic Bulge monitoring (see ATel #438) has started on 2009 Feb. 21st. During the latest observation between 2009 Feb 25 13:21 and 17:02 (UT) a type I X-ray burst from SAX J1747.0-2853 (1A 1743-288, aka GX .2-0.2) was detected by JEM-X at UT 14:50:51 (MJD=54887.61865). The burst profile showed clear evidence of a photospheric radius expansion event and the peak flux reached 1.6 Crab (4.2x10-8 erg/cm2/s) in the 3-25 keV range.
