   The object was recorded about 2.0 mag fainter than on Nov. 12.
On Nov. 13, Kiyoshi Kasai (Switzerland) recorded the apparent fading
branch.  The superhumps were present between eclipses at this moment.

   The eclipses became deeper (2.0 mag) on Nov. 13.  Both features of
remaining superhumps and sign of orbital humps appear to be present,
but the identification requires further observation and analysis.
