Re: [vsnet-chat 1205] Re: V592 Her position One thing I forgot to mention. The spectroscopic confirmation by Dr. Mennickent, together with the extremely large outburst amplitude, strongly suggest the system belongs to the WZ Sge-class of dwarf novae. The orbital (or superhump) period is expected to be around 1.3-1.4 hour; this predicted shortness of the period will make full-phase observation easiler than in other SU UMa stars. In known WZ Sge-type systems, what is called early superhumps, orbiral superhumps, or outburst orbital humps (nomenclature depending the authors) appear, which are characterized by the double-wave (Porb/2) signals. The outburst amplitude of 9.5 mag (or more) is the far exceeding the previous records of WZ Sge-type systems (even WZ Sge itself had 8.5 mag). This is clearly the first-ever opportunity in revealing in such dwarf novae with tremendously large outburst amplitudes. Only few known of them exceed the 9 mag amplitude, and none were observed in terms of short-term variability. Regards, Taichi Kato
