940921.805 125 SNO 940923.832 128 VAN 940925.542 132: Myy 950716.933 127 VAN 950719.956 131 VAN 950720.925 135 VAN
The first ever detection of superhumps was made during the 1994 September outburst by the Ouda team (Nogami and Kato, IBVS 4227), who reported a superhump period of 0.0805 +/- 0.003 day. Observations during the present outburst of better visibility are strongly recommended.
