Abstract The INTEGRAL Galactic bulge monitoring program (see ATel #438) observations obtained between 2011 Feb 13 11:30 and 15:11 UT show continuing soft X-ray activity from SAX J1747.0-2853 (ATels #3123, #3163). The JEM-X instrument detects strong flaring activity between 80 and 700 mCrab (3-25 keV). The average JEM-X spectrum is well described (reduced chi-squared is 1.1 for 11 degrees of freedom) by an absorbed black body plus power law (fixing the interstellar absorption, N_H, to 9e22 cm-2, Natalucci et al.
