Dear Dr. Kato,

The GCVS team identifies CK Dra with GSC 3872.0919. The light curve
published by A. Wittmann, Mitt. veraend. Sterne, 1968, Bd. 4, H. 7, 175 is
very bad. However, Wittmann reports times of 12 minima in Mitt. veraend.
Sterne, 1961, No. 577. Three additional minima were reported in BBSAG
Bulletins Nos. 91, 97, 112, 1989 - 1996, all in reasonable agreement with
the GCVS light elements. The case seems clear - but... Please keep us
informed.
