In order to
encourage observers to assist in the Classical Cepheid Program (Cragg, 1972) we
have started to develop new magnitude sequences for those stars requiring them.
203935 X Cyg, and 021959 SZ Cas are the first to be completed. For X Cyg the
sequence stars are bright enough to have been measured with a photoelectric
photometer attached to an 8" reflector. The new magnitudes have been
incorporated into an existing 'a' chart and a new 'b' chart drawn by C. B.
Ford. X Cyg is a binocular object throughout its range of about 5.8 to 7th
magnitude, and is conveniently located near Epsilon Cygni. This star should be
