We report the detection of a new X-ray outburst of the recurrent X-ray transient and black-hole candidate 4U 1630-47. The All Sky Monitor aboard the Rossi X-ray Timing Explorer began detecting the source on or near 2002 September 10, when it rapidly rose to 0.3-0.4 Crab (2-12 keV) on 2002 September 13. This renewed activity of 4U 1630-47 follows its last outburst which started in 2000 November and lasted until 2001 June. During its 1998 outburst, the radio and possible IR counterparts of the source were detected (Hjellming et al. 1999, ApJ, 514, 383; Augusteijn et al. 2001, A&A, 375, 447; VLA radio position R.A.=16h34m01.60s +/- 0.05s, Dec.= -47 23' 33" +/- 2", equinox 2000). Therefore, observations of this source at all wavelengths are strongly encouraged.
