BC UMa superhump period update

Dear Colleagues,

   We have updated the superhump period of BC UMa by combining the new
data set provided by Nick James.  Thanks to the long basedline established,
we have now obtained a very accurate superhump period 0.06452 d.
Upon receipt of the data of Novak's team, we will be able to update
the result.  Superhumps are still prominent, and some QPO-like features
are superimposed.

Regards,
Makoto Uemura, Taichi Kato, Sergei Shugarov, Elena Pavlenko, Patrick Schmeer,
Nick James, Rudolf Novak, Gianluca Masi
On behalf of the VSNET collaboration team
