Dear all,

   We have received further data from Berto Monard, Roland Santallo,
Nakajima-san, Maehara-san and Peter Nelson.

   The superhump signal has become stronger, with more typical
superhump-type profiles.  The mean period since May 10 is
0.054192(6) d.  There has been significant evolution of the
overall hump profile.  If we take this as a "face value", the
current peaks of superhumps correspond to the secondary maxima
that appeared on May 5, suggesting that current modulations are
late superhumps.
