HV Vir: further development of superhumps!

Dear Colleagues,

    We have received new data from Kiyota-san, Torii-san, and Rudolf Novak.
We have also analyzed new Kyoto data.

    The light curves show extremely clear superhumps (triangular shape),
with an amplitude of 0.2 mag.  The analysis of earlier data has also
confirmed that the final transition to early superhumps to genuine superhumps
took less than 5 hours, quite comparable to a sudden change observed
in WZ Sge.

    We proceed to further detailed period analysis.

Regards,
Taichi Kato
