[vsnet-alert 9857] Re: OT_J084555.1+033930 superhumps

[Hiroyuki Maehara]

Dear colleagues,

We have received time-series data on Jan. 25 and 27 from Nakajima-san.
The data clearly show ordinary superhumps. The amplitude of superhumps
was 0.3 mag on Jan. 25 and 0.2 mag on Jan. 27.
A PDM period analysis for the combined data yields 0.06032(10) days
as the best estimated superhump period. This period is slightly longer
than those of other WZ Sge-type stars. As commented by Kato-san in
vsnet-alert 9852, the object seems to be an SU UMa-type star with 
large outburst amplitude rather than a typical WZ Sge-type star.

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