OT J012059.6+325545: early superhump phase continues
We have received further data from Shiokawa-san, Maehara-san,
Seikei High School team (Kyoto data will be available soon).
The data indicate that early superhumps still dominate!
The mean period since Dec. 7 has been 0.05717(2) d, and the amplitude
of the humps is 0.04 mag. The profile, however, more resembles
that of ordinary superhumps, with a sharp first maximum and a broader
second maximum. If these humps are indeed early superhumps,
the duration of this stage is long (comparable to >12 d for V466 And,
10-14 d for AL Com 2001, 12 d for WZ Sge 2001, 10-12 d for OT J0042).
Continued intensive observations are highly encouraged!
