4U 1630-47 extended X-ray outburst

   According to ATEL #161, the black hole candidate X-ray transient
4U 1630-47 is undergoing an extended X-ray outburst (duration nearly
260 d).  There have been occasions of increased X-ray activities
recently.  For more details, see ATEL #161.  I hope that Uemura-san
would provide further instruction for optical/IR observations.

   The object is located at:
   16:34:00.4 -47:23:23 (J2000.0)

Regards,
Taichi Kato
