Abstract (from CDS):
As a first step in the DIRECT project, between September 1996 and October 1997 we obtained 95 full/partial nights on the F. L. Whipple Observatory 1.2 m telescope and 36 full nights on the Michigan-Dartmouth-MIT 1.3 m telescope to search for DEBs and new Cepheids in the M31 and M33 galaxies. In this paper, the fifth in the series, we present the catalog of variable stars found in the field M31F [(α,δ)=(10°.10,40°.72), J2000.0]. We have found 64 variable stars: four eclipsing binaries, 52 Cepheids and eight other periodic, possible long-period or nonperiodic variables. The catalog of variables, as well as their photometry and finding charts, is available via anonymous ftp and the World Wide Web. The complete set of the CCD frames is available upon request.
