ASASSN-17pn: fading

     Shugarov's team, Tamas Tordai, Itoh-san and Kyoto U. team have reported further
observations.
     Although the object rapidly faded to <17 mag on Dec. 27, continuous observations
or monitoring are strongly encouraged. Because the object is a good candidate of a period
bouncer, and it is expected to detect further rebrightenings and late-stage superhumps.
     We succeeded in detecting the stage A-B transition on Dec. 17. The period of stage
A and B are 0.06042 (6) d and 0.05990 (2) d , respectively. Due to the lacking data,
there have not been the signal of late-stage superhumps yet.
