[vsnet-outburst 7215] More on new SU UMa star in Tau (OT_J032912.3+125018)

[Taichi Kato]

   Updated results from ATEL on the new SU UMa star in
Taurus (OT_J032912.3+125018).  Such a systematic decrease in
the superhump amplitude is rather unusual if the outburst was
detected near the optical maximum.  Together with the shortness
of the superhump period, this object naturally deserves further
follow-up observation.  Might be an LL And analog?

We report the results of time-resolved CCD photometry   obtained with
the Mount Laguna Observatory 1-m reflector   of the recently-discovered
variable star in Taurus (CBET #701).   A total of ~20 hours of V-band
photometry over six nights   (2006 Oct 28 - 30; 2006 Nov 01 - 03) has enabled
us to confirm its   tentative identification as a previously unknown SU
UMa dwarf nova,   and to establish a revised superhump period   of 0.05338(1)
days (76.87 min).   During our observations the system faded by   an average
of ~0.08 mag per day, from a mean magnitude of V~15.6 on   2006 Oct 28.3,
to V~16.1 on 2006 Nov 03.3. Over roughly the   same interval, the superhump
amplitude   decreased from ~0.15 mag on Oct 28.3 to   ~0.05 mag on Nov
02.4. By the following night (Nov 03.3),   the superhump amplitude   had
decreased to less than 0.05 mag, rendering it impossible to   measure reliable
timings from our data.   Further observations are encouraged to follow
the evolution of this   newly-discovered SU UMa star, and to establish
its magnitude at minimum light.
