V359 Cen: definite SU UMa-type dwarf nova!
Dear Colleagues,
Roland Santallo (Southern Stars Observatory Tahiti) has just reported
the result of time-series photometry of V359 Cen on May 31. The lught
curve shows a fully developed superhump signal with an amplitude of 0.30 mag!
The object is thus confirmed to be a genuine SU UMa-type dwarf nova.
Owing to the relatively long superhump period, we have not been able to
precisely determine the superhump period. However, the light curve indicate
that the period is around (or slightly longer than) 2 hrs, which makes
V359 Cen as one of below-the-gap SU UMa-type systems with the longest
orbital periods (the system may be on the border the period gap).
Further observations (hopefully longer than 3 hours) are most urgently
requested!
Regards,
Taichi Kato
