OV Boo: complex profiles of (early?) superhumps

     Arto Oksanen, Enrique de Miguel, Domenico Licchelli, Pavol Dubovsky, Shugarov's team,
Crimean Astrophys. Obs. team(Sosnovskij, Pavlenko and Pit), Kyoto U. team, Franky Dubois
and Kiyota-san have reported new observations.
     The object was 13.6 V on Mar. 25 and has shown (early?) superhumps. The amplitudes
was weakened (~0.15 mag) and the depth of eclipses was about 0.15 mag. The superhumps has
shown complex profiles. Ordinary superhumps may have contaminated the early superhumps.
     Further observations are strongly encouraged to clarify the stage transition!
