V404 Cyg: violent short-term variations

   Colin Littlefield has reported new observations with
6 sec resolution.  The data showed fluctuations down to
the time resolution!  The data partly overlaps with
de Miguel's run, and the short-term variations well
agreed each other.  As already pointed out in
vsnet-alert 18742, the current variation looks very
similar to V4641 Sgr during the 2002 and 2003.

   Please continue the present excellent coverage.
Let's see whether the current phenomenon develops into
a major outburst as in 1989.
