Abstract

(Abstract only) NSV 7814 was first observed to vary around the turn of the century when K. Graff (1921, Astron. Nachr., 213, 176) used it as a comparison star for observations of SS Her. Our data span 548 days and total 84 magnitude estimates. The observations suggest a very short period eclipsing binary that varies from visual magnitude 11.2 to 12.2.
