Re: OT J012059.6+325545: transition to ordinary superhumps!

   We have received observations from Terskol team (large set, Maksim Andreev),
Crimean Astrophys. Obs. team (Denis Samsonov, Oksana Antonyuk), both relayed
by E. Pavlenko.  We expect to receive observations from Japan (not received yet).

   The mean period of early superhumps (up to Dec. 7) was 0.057157(4) d.
Based on the first night observations of ordinary superhumps, the period
is still indistinguishable from the period of early superhumps despite
that the profile is indeed that of ordinary superhumps (not longer, e.g.
by 1%).  This might reflect the very early evolutionary stage of ordinary
superhumps, whose initial period might be close to the period of ordinary
superhumps.  A very interesting phenomenon! (see also
