            NOTES ON NEW VARIABLE STARS


        HD +54d2193(5.8m)

        The variability of BD +54d2193 was announced by M.S. Snowden
  in IBVS 127. I wish to point out that the variability of this star was 
already discovered in 1928 at the Babelsberg Observatory. In 
Vierteljahrsschrift der Astr.Gesellschaft Bd 64; p.156 (1929) the epoch of a
patrol plate (J.D.2425507.420; 1928 Sep.17), showing the star faint,was
given.

        Elements of this star have been given in the following 
numbers of the IBVS:
           No  47: elements
           No  77: improved elements and photometric light curve.
           No 136: independent discovery of the variability by R. Deurinck
and R. Briers, elements and light-curve.

        Elements given in numbers 77 and 136 are fully compatible as
may be seen by two half-minima on new patrol plates of the Bamberg
Southern Station, fitting the light-curve of No 77 with the elements of
No 136.

by Strohmeier (Ver.d.Remeis-Sternwarte, Bamberg Bd V: Nr 8.)
is identical with V 796 Cyg (19h31m3s +47d05.'6;  1900.0), as was
found by the second author observing the star on our patrol plates.

        V 796 Cyg = S 4782 was discovered by Hoffmeister at Sonneberg.

        From 130 photoelectric observations during 5 nights between      
1966 April 26 and May 2 the following 6 Minima could be derived.

        The O-C' s have been obtained from the elements given in
IBVS 57, 1964. They show that the period was constant during the last
5 years.
