V404 Cyg: rising now and short-term variations

Pavol A. Dubovsky, Tamas Tordai, Klaus Wenzel, Roger Pickard,
Kiyota-san, Lew Cook, Maeda-san, Enrique de Miguel, Colin Littlefield
have new observations.
The light curve still showed short-term oscillations (within a few seconds)
with various amplitudes (~0.1 mag).
In a few minutes, large amplitude variations (0.5~2.0 mag) were observed.
Surprisingly, the mean magnitude was about 11 mag in I band.
On average, V404 Cyg is brighter by about 1 mag than it was yesterday.
Please continue the excellent observations.
