During the last galactic plane scans performed with the INTEGRAL observatory on 29 Aug, 2004 an increase of the flux from 4U0115+634 was detected, that can be connected with the beginning of possible new outburst. The source was detected with IBIS and JEM-X telescopes around UT17:00 with a total effective exposure of a few ksec at the level of ~10 mCrab and 25-30 mCrab in 18-60 keV and 4-20 keV energy ranges, respectively. We encourage follow up observations at various wavelengths.
