4U 1630-47 is among the most active of the BHC X-ray transients and has produced strong hard X-ray emission during its 17 detected outbursts as well as highly polarized radio emission, indicating the presence of jets. The current outburst from 4U 1630-47, which began in 2002 September, is one of the brightest and longest recorded outbursts from this system, and, during this outburst, we have observed the source with INTEGRAL and RXTE. These observations have allowed us to study the broad-band energy spectrum and extreme flaring activity from this source. In addition, 4U 1630-47 lies in the Norma region of the Galaxy, and the line of sight is tangent to the Norma-Scutum Galactic arm. The hard X-ray images from INTEGRAL show several new sources. In this paper, we present our results from the INTEGRAL and RXTE observations.
