Scientific paper

From May 1983 to April 1985 the VY CMa source was observed in the 1665-, 1667-MHz principal OH maser emission lines with the RATAN-600 radio telescope, at 2.6 x 45 arcmin x 5.4 km/sec resolution. An OH flare in February-March 1985 was accompanied by the emergence of satellite features symmetric about the strongly variable dominant 1667-MHz peak. The possible geometry of the maser emission site is discussed.
