[vsnet-outburst 8479] Re: OT_J074727.6+065050 (new CV in CMi) superhumps

[Hiroyuki Maehara]

Dear colleagues,

I carried out time-resolved photometry on Jan. 21.
The data clearly show superhumps with an amplitude of 0.13 mag.
The period of superhumps estimated from maximum timings of superhumps
is 0.0621(2) d. This period is slightly longer than that of typical 
WZ Sge-type dwarf novae.

Follow-up observations are strongly encouraged.
Please report your time-series observations to:
vsnet-campaign-report at ooruri.kusastro.kyoto-u.ac.jp

Best regards,
Hiroyuki Maehara
