Bouchet, Centre d'Etude Spatial du Rayonnement, Toulouse; and A. A. Lutovinov, Space Research Institute, Russian Academy of Sciences, Moscow, report the detection of the first transient source observed by the ISGRI detector of the IBIS instrument onboard the European Space Agency's INTEGRAL satellite. The source appeared at R.A. = 16h31m52s, Decl. = -48o48'.5 (equinox 2000.0; uncertainty about 2'), while INTEGRAL was performing an observation of the Galactic plane on Jan. 29.271 UT. The source flux in the band 15-40 keV was 50-100 mCrab. The source was observed to vary significantly on a timescale of 1000 s. INTEGRAL will observe the source again during Feb. 1-3. Observations at other wavelengths are encouraged.
