Winkler, Research and Science Support Department, ESTEC, Noordwijk, report the discovery with the INTEGRAL satellite (+ IBIS/ISGRI) on Mar. 19.4 UT of a variable source located at R.A. = 16h35m.8, Decl. = -47o26' (equinox 2000.0; position uncertainty 1'.5). The source flux varied by a factor of about 2 on time scales of hours. The average fluxes were about 50 mCrab in the energy band 15-40 keV and 20 mCrab in the band 40-100 keV. Observations in other bands are encouraged.
