During a Galactic Plane Scan on September 12th 2004, the INTEGRAL gamma ray observatory detected the high mass X-ray binary 4U 0115+63. Increased activity was first noticed by the IBAS gamma ray burst detection software at 14:53 UTC, leading to the generation of three alerts (1978-79-80). The source was visible in the ISGRI field of view until 16:24 UTC. The source was also visible in the JEM-X x-ray monitor in one Science window (2 ksec observation starting at 15:31 UTC) leading to the following estimated fluxes: JEM-X: 3-10 keV ~500 mCrab; 10-30 keV ~750 mCrab ISGRI: 20-60 keV ~400 mCrab; 60-200 keV ~25 mCrab.
