V4641 Sgr photometry from Berto Monard

Dear Colleagues,

   We have received time-series CCD photometry on May 20-21 from Berto Monard.
The light curve is very complex and very short-term fluctuations up to
0.4 mag is observed (the light curve even resembles a X-ray light curve
of some black hole binaries!).

   We have also successfully obtained CCD observations at Kyoto.
The analysis is in progress.  More detailed analysis will be presented
by Uemura-san.

Regards,
Taichi Kato
