OT J213806.6+261957: fading stopped, large-amplitude superhumps
According to the most recent observation by Enrique de Miguel Agustino,
the rapid fading has stopped. Large-amplitude superhumps have emerged.
Comments: Very good weather conditions. The object has faded by
as much as 1.22 mag since last run. The most significant
feature is that the superhumps are large
in amplitude, between 0.20-0.30 mag. There seems to be
hints of double-hump (or triple-hump)
structure of the superhumps.
As for the superhump period, P_sh = 0.055203(25)d, with
a prominent close peak at P=0.054935(30)d.
