The superhumps have become even clearer, and the depths of eclipses
became smaller (0.5-0.7 mag) with rather complex detailed features.
The profiles of eclipses and superposed superhumps were highly variable
from time to time, !
V2051 Oph is apparently displaying another example of complex behavior
in a short-period, high-inclination SU UMa-type dwarf nova in developing
superoutburst!
