           V381 CYGNI AN RR LYRAE TYPE STAR

V381 Cygni is listed in the General Catalogue of Variable
Stars as a Cepheid with a period of 4.88d. On the basis of 650
plates at the Maria Mitchell Observatory examined by a student,
Beverly Kehoe, we have been unable to confirm this period. I have
therefore independently analyzed the observations and find they
are well represented by a reciprocal period of 1.639305d (Figure,
where magnitudes are on an arbitrary scale). The resulting ephemeris 
is

           Max.= 2439005.667+0.6100146d E.

                        [FIGURE 1]

   This period turns out to be just one eighth of the one originally 
published by Beljawsky (1936). His indicated epoch of maximum
(represented by the small vertical bar in the Figure) is also
satisfied by the above relation.
   The Nantucket observations span the years 1926 through 1976.
