V404 Cyg: large amplitude variations

      de Miquel has reported new observations.
The light curve showed unusual variations with amplitudes ~2.5 mags
in short time scale (a few minutes ~ an hour).
Such variations are very rare. They remind us of V4641 Sgr.
This X-Ray transient underwent an outburst for the first time in 26 years.
Further observations are encouraged.
