V404 Cyg: rapidly fading

      Pavol A. Dubovsky, Tordai Tamas, Josep Lluis, 
and Enrique de Miguel have reported new observations. 
This object was rapidly fading in the ratio of 1 mag to 6 hours. 
The present magnitude is about 15 mag in I band.
It is fainter by 6 mag than that of two days ago, and is the same as 
the magnitude when this outburst was detected for the first time. 
The light curve still showed large amplitude variations (0.5 ~ 2.0 mag). 
However, the interval of these variations became longer (~ 2.5 hours). 
The behavior of this object is in a mystery, so
further observations are encouraged.
