NSV 10934: superoutburst of a new SU UMa-type dwarf nova!
Dear Colleagues,
Chris Stockdale has reported fully reduced time-series observation of
NSV 10934 taken on January 4. The data clearly show superhumps with
amplitude of ~0.15 mag. A preliminary period analysis has yielded a
period of 0.0743(8) d, which is naturally subject to further refinement.
The object is now firmly established to be an SU UMa-type dwarf nova.
Congratulations, Chris! Monard's preceding observation must have caught
the growing stage of the superhumps.
The period has also confirmed a suggestion that "the orbital period of
NSV 10934 is expected to be slightly longer than that of HT Cam (86 min)"
(Kato et al. 2002, A&A 396, 929), although a conparison with HT Cam would
require further observations of both objects.
Regards,
Taichi Kato
