[vsnet-campaign 626] RZ Leo superhumps update

RZ Leo superhumps update

Dear Colleagues,

    We have received high-quality data from Kiyota-san (Tsukuba, Japan)
on Dec. 26.  The Kyoto team also obtained a 5.4-hour run under mostly
clear skies.  The combined data (Dec. 23-26, 2541 points), including the
data from Rudolf Novak (vsnet-campaign 625), has yielded a superhump
period of 0.07851 d, which is slightly shorter than the previous
determination.  This may suggest a shortening of the superhump period.
Superhumps have become narrower, more resembling those of usual SU UMa
type stars.  Secondary superhump maxima (small notches) were visible both
on Tsukuba and Kyoto data.  More detailed analysis will be presented
by Ishioka-san.

Regards,
VSNET Collaboration team
