Abstract

The low-mass X-ray binary and burster source KS 1741-293 has been detected during recent INTEGRAL Galactic bulge (see ATel #438) observations by the JEM-X instrument.

On February 25, 2010, between UTC 13:04 and 14:08, KS 1741-293 was detected at a 3-10 keV flux of 9 +/- 4 mCrab, and an upper limit of 2 mCrab between 10-25 keV.
On Feb. 28, between UTC 11:31 and 15:12, the source flux was 7 +/-2 mCrab and 13.5 +/- 4.5 mCrab, respectively.
No X-ray burst was detected.

Previous upper limits from similar observations performed on Feb. 13, 16, 19, and 22, were 5 mCrab and 2 mCrab, respectively in the same energy bands.

The region will be observed again by INTEGRAL on March 10, and the regular INTEGRAL monitoring of the Galactic bulge will continue until April 17, 2010.
We encourage follow-up observations of this source at all wavelengths.
