Following the announcement of the discovery of the new transient XMMSL1 J171900.4-353217, we noticed that INTEGRAL was pointing in the direction of the source in the same period of the XMM-Newton slew.

XMMSL1 J171900.4-353217 was in the IBIS/ISGRI FOV from 2010 March 09 at 11:17 to 2010 March 11 at 12:23 (UTC), during the satellite revolution 904. The source was not detected in the IBIS/ISGRI mosaic.

By using the different observational subsets available in Rev. 904 we determined 3 sigma upper limits on the source X-ray flux between 8 and 18 mCrab (20-40 keV energy band).

A 3 sigma upper limit of 6 mCrab (20-40 keV) was obtained by summing up all the observations (effective exposure time 59 ks).

XMMSL1 J171900.4-353217 was outside the JEM-X2 FOV during the entire observational period.
