Abstract

V448 Cygni is a long neglected eclipsing binary star; no minima have been published since 1948. One hundred and five photoelectric observations of this star were made during the latter part of 1978. Results indicate that Ashbrook's 1942 ephemeris is nearly correct. A slightly revised ephemeris is derived and the obtained light curve is presented. The nature of the eclipse remains unresolved, although the existing evidence seems to favor partial eclipses somewhat.
