Shape of the light curve and depth of minima vary. Brightness of the secondary (G8) varies sporadically. Subgiant brightening accompanies eruptive mass transfer. The gaseous stream moving to the primary (B7) component forms around it gaseous ring or disc [08889].

Please put the variable's designation into field in common style - for example: ZUMa, zuma, V477Cyg, v1182Cyg, NSV 255, nsv2544. Designation of bright variable stars like Beta Persei type in short style (three letters) - bet Per. The complete cross-identification among more then 30 catalogues will be done after submitting.
