[vsnet-campaign-dn 9357] RZ LMi: negative superhump signal and lst superoutburst

[Ryoko Ishioka]

Dear VSNET observers,

RZ LMi is now at its NON-superoutburst phase. Light curves from
Stefano Padovan and Donn Starkey at its minimum state show clear humps
with a period shorter than its superhump period and possible orbital
period. It might be a signal of negative superhumps.

The last superoutburst was observed by Stefano Padovan, Shawn Dvorak,
OKU team,  East Scope of Tien Shan Observatory, Tenagra Observatory,
and Lulin Observatory. The data detected some period variation around
the averaged superhump period of ~0.0594d.

Further time-series observations during the current NON-superoutburst
phase will be very helpful to confirm the modulation. Any kinds of
observation will be appreciated, though.

Best Regards,
Ryoko Ishioka
