   Time-resolved photometry on Feb 14 by Nakajima-san clearly
show double-humped early superhumps.  The full amplitudes were
around 0.1-0.15 mag.  This observation probably caught the
earliest evolution of early superhumps (not yet recorded in
HV Vir in the past).  Further observations are very strongly
encouraged.  The last superoutburst occurred in early 2002
(cf. Ishioka et al. 2003,
http://adsabs.harvard.edu/abs/2003PASJ...55..683I )
The interval between superoutbursts now look similar to that
of AL Com.
