BO Cet fading (IW And state)

   Recent contributions have been mainly by Itoh-san,
Josch Hambsch and Kyoto U. team.

   Itoh-san just detected rapid fading on Jan. 11.
It looks like that the object experienced the following
sequence:

(SU UMa state)
   superoutburst in 2020 Oct.-Nov.
   three normal outbursts in 2020 Nov.-Dec.
(from here IW And state)
   slowly rising standstill in 2020 Dec.-2021 Jan.
   brightening on 2021 Jan. 6-10.
   fading Jan. 11-

   Although I didn't perform a period analysis, no
remarkable superhumps were present recently.
