   Would it be possible to check the exact dates of Moscow plates containing
the DO Dra field?  We can then look for the plates which were near the
center of the published YY Dra eclipse ephemeris.  If DO Dra was indeed
faint at such moments, the star might have been a misclassified variable
star and DO Dra = YY Dra.  If DO Dra was recorded normally, we can exclude
the possibility of DO Dra = YY Dra.
