We report the detection of an outburst from MXB1730-335 (Rapid Burster)
with the INTEGRAL observatory during ultra deep observations of
the Galactic Center field. In observations during Apr. 14 UT08:20 -
Apr. 14 UT18:00, 2005 the source flux increased from undetectability
(<2 mCrab) to 17+/-2 mCrab in the 18-60 keV energy band. The source was
only marginally detected with JEM-X on the level of 15 mCrab in the energy
range 3-20 keV. No bursting activity was observed.
Practically continuous observations of this region of the sky with
INTEGRAL are scheduled through Apr. 21, 2005.
