Dear colleagues,
I performed time-series photometry of the object last night.
The data show superhumps with an amplitude of ~0.5 mag.
The superhump period is around 0.057 d.
CSS080304:090240+052500 is a new large-amplitude SU UMa-type (or
WZ Sge-type) dwarf nova.
Further observations are encouraged.
Best regards,
Hiroyuki Maehara
