[vsnet-alert 302] detection of superhumps in V701 Tau

[tkato@kusastro.kyoto-u.ac.jp]

Dear Colleagues,

    V-band time-resolved CCD observations of V701 Tau (Dec. 27.446 --
27.706 UT) finally revealed a development of superhumps in V701 Tau.
Superhumps were still small in amplitude (~0.05-0.06 mag), but are clearly
present and are likely to be just growing.  A preliminary analysis gives
the best period of 0.073 day.  The present observations has thus firmly
established the SU UMa-type nature of this dwarf nova.

    Congratulations on Tonny Vanmunster on his visual discovery of an
outburst of this faint dwarf nova, and we would like to express sincere
thanks for his and his colleagues' nightly efforts in monitoring such faint
objects and prompt notification; without either of them, the early develop-
ment of superhumps (or even the outburst) would have been easily missed.

Regards,
Taichi Kato & Ouda team
