ASASSN-17gf: new SU UMa-type DN below the period minimum

     Josch Hambsch and Berto Monard have reported new observations.
The object has clearly shown growing (stage A) superhumps with a
period of 0.0532 d = 76.6 min.
     The period is below the empirical period minimum of 78-82 min, and
the 3rd shortest in usual SU UMa-type DNe as far as I know. Further
observations are strongly encouraged.
