For those interested in more details on UV Gem's outbursting nature : - The SU UMa-type nature of UV Gem was detected in December 1999 (vsnet-alert 3821). - CCD photometry results of the April 2002 superoutburst of UV Gem are presented on my web site (www.cbabelgium.com), including a periodogram and phase diagram. - I also did CCD photometry on UV Gem in December 2000. UV Gem underwent a long outburst at that moment, but my photometry results did not reveal superhumps. I assume this is the long outburst Taichi is referring to in his message below.

Although the SU UMa-type nature of UV Gem has been established, there has been a report that at least one of long outburst did not show clear superhumps. Further observations are clearly needed!
