V503 Cyg: rapid decline from the superoutburst

    The Kyoto observation last night clearly shows that V503 Cyg
have entered a rapid decline phase from the current superoutburst.  
The object faded with 0.18mag/d until December 6.469, and then, 
became 1.31mag fainter on December 7.454.

    The last night time-series observation shows a possible short-term 
variation (superhump or late superhump?) with a relatively large 
amplitude of ~0.5mag.
