V877 Ara: new SU UMa-type dwarf nova!

,

    On 9 june We (Southern Stars Observatory, Tahiti French Polynesia)
conduct time-series photometry of V877 Ara (NSV08383)
The data show fully developed superhumps (amplitude 0.25-0.30 mag),
establishing that V877 Ara is a new member of SU UMa-type dwarf novae.
Although exact period determination is still difficult on single-night
data, the system has a relatively long (around 0.08 d) superhump period.
Observers are strongly urged to continue observation as long as possible
(prefreably more than two superhump cycles per night) in order to precisely
determine the superhump period.

V877 Ara image and position


. 

    This object seems to be correpond to

USNO0225.27372547 171653.966 -653251.46 (2000.0) 20.3 21.6

    which is different from previous identidications.  More detailed
identification awaits Yamaoka-san's astrometry (Vsnet Team).  The quiescent counterpart
seems to be much fainter than was previously thought.  This is consistent
with the superhump detection.

    Anyway, observers should refer to the above image before observing,
since the position has a large offset from the GCVS/NSV/Downes catalogs.
Further obseravtions are very strongly requested!
