 We have received further observations from  William L. Stein. 
Though obtained data shows continuously superhumps and eclipses,
stage B-C transition may have occurred around 22th of Jan
judging from O-C value. Since this object is in stage C now,
the decline will occur in near future. Further observations
are required.

is obtained as the mean superhump period in stage B. Refined 
eclipse period is 0.066047 (6) d.
