I used 5 wide field CCD frames obtained by L. Smelcer
originally for AY Dra, (CK Dra is there too). which
confirmed variability of CK Dra = GSC 3872 919, as drawed on
B.R.N.O. and MEDUZA charts. The star seems to have also some
secondary minimum.

Best regards,

P.S. AY Dra is now at 13.4 mag and gradually fades with rate
0.05 mag/day.
