Var73 Dra superhump period

Dear Colleagues,

   A preliminary analysis of Starkey's data (+alpha) now favors a superhump
period of 0.1051(2) d.  This period would make Var73 Dra a "twin" system
with the NY Ser, an SU UMa-type dwarf nova in the period gap
(Nogami et al. (1998) 50, L1), although other aliases are still possible.
We will be able to refine the period with an upcoming combined analysis
of the entire data.

Regards,
Taichi Kato
