HV Vir : superhumps may appear

We notice that superhumps may appear in the light curve
of HV Vir on 20 Feb. Our preliminary light curve indicates that
amplitudes of humps are about 0.15mag in V-band.

The decline rate of the object becomes slower than
in the early superhump stage, between 14 Feb and 19 Feb.

Our preliminary results were shown in our blog.

Followup observations are encouraged.
