KK Tel: new SU UMa-type dwarf nova in superoutburst!
Dear Colleagues,
Peter Nelson has sent time-series photometry of KK Tel. The data clearly
show 0.12 mag superhumps. Although the period is not well established,
the object seems to have a rather long (~0.08 d) superhump period.
This observation confirms the long-suspected SU UMa-type nature of KK Tel!
Congratulations to Peter Nelson on this remarkable detection!
The published suspected orbital period is 2.02 hours (Howell et al. 1991,
PASP 103, 300). The present observation seems to be consistent with
this period.
Further observations are strongly encouraged to precisely determine
the superhump period. Peter Nelson also commented the presence of a
close companion. The images has been delivered to Yamaoka-san for
accurate astrometry and quiescent identification.
Regards,
Taichi Kato
