HO Del superhumps up to now

   HO Del has now apparently entered the late stage of superoutburst
evolution.  The mean superhump period up to now is 0.06439(1) d,
slightly shorter than the 1994 measurement.   The full growth of
the superhumps was recorded on Aug. 4.  Between Aug. 4 and 8,
the superhump period increased at dot(P)/P = +10(2)*10^(-5).
Following this, the period showed an apparent transition to
a shorter period, the behavior frequently seen in SU UMa-type
dwarf novae with similar superhump periods.

   We are happy to receive any further data (past and future)
