We report a detection of the outburst from
MXB1730-335 (Rapid Burster) with the INTEGRAL
observatory during the deep observation
of the Galactic Center field. The source was
detected on Aug 28, 2003 with a flux of ~30 mCrab in the
15-40 keV energy band. The
observations on Aug 29 UT14:40 - Aug 30 UT11:30, 2003
showed that its flux increased to ~70 mCrab in the
15-40 keV energy band and 20 mCrab in the 40-100 keV energy band.
According to our knowledge this is the strongest outburst
in hard X-Rays during the whole history of Rapid Burster
observations.
