[vsnet-alert 7581] CT Hya superoutburst?

CT Hya superoutburst?

  As reported by Rod Stubbings, the large-amplitude SU UMa-type dwarf nova
CT Hya is undergoing a bright outburst.  The outburst may be a superoutburst.
The last reported superoutburst occurred in 2000 December.  Although several
past superoutbursts have been observed by the VSNET Collaboration, early
coverage of a likely superoutburst is still very wanted.

  The star was claimed to be something intermediate between usual SU UMa
stars and WZ Sge-type stars (or TOADs), see Nogami et al. 1996
(PASJ 48, 607).  Early coverage is thus extremeely important to see
whether there is any similarity of the superhump growth with WZ Sge-type
stars.
