[vsnet-alert 9729] Re: Fw: [cvnet-outburst] Re: OT_J080714.2+113812: new dwarf nova in Cnc - SUPERHUMPING!

[Hiroyuki Maehara]

Dear colleagues,

I performed 4 hours time-series photometry of this star last night.
The data show superhumps with an amplitude of 0.1 mag.
The superhump period estimated by PDM method is 0.0614 days.

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

Best regards,
