Аннотация:We combined photographic, photoelectric and CCD observations of the nova-like variable
V380Oph to get a light curve spanning the time range of 40 years. While the typical high-
state brightness of V380Oph was R ~ 14.5, two low-brightness episodes identified in 1979
(Bpg ~ 17.5) and 2015 (R ~ 19) confirm its classification as a VYScl-type “anti-dwarf nova”.
The Fourier period analysis of photoelectric and CCD V and B observations obtained in 2002–
16 revealed the presence of two periods 0d.148167 and 4d.287, that may be associated with
negative superhumps and disc precession. We also compared measurements obtained with the
iris micro-photometer and flatbed scanner at the same plates and found an agreement within
the expected accuracy of photographic photometry.
