V503 Cyg : orbital humps?

 We have received observations from Colin Littlefield. These
data show that this object underwent a normal outburst on Jul
18.
 To be interesting, the period of variation seem to have 
changed affer this normal outburst, although not very confirmed. 
The period after the period change appears to be near that of
the orbit.
 In order to confirm this clearly, further observations are
required!
