Abstract
NSV 10934 was discovered as a large-amplitude suspected variable star of unknown classification. We noticed that the object is identified with a bright ROSAT X-ray source (1RXS J184050.3-834305). Systematic monitoring of this object by the VSNET team revealed four outbursts between 2001 and 2002, confirming the dwarf nova-type nature of NSV 10934. The outbursts were characterized by a rapid fading (1.5 mag within 0.90 d) toward the end of the outbursts. Combined with the strong and relatively hard X-ray detection, this outburst behavior suggests that the object may be related to the recently discovered intermediate polar, HT Cam (astro-ph/0206184).
