We have observed BF Eri these six days.
It is fading with 0.4mag / day, and it was about Rc = 13.6 mag yesterday.
We have detected humps which seem to have a periodicity of about three hours.
Its anpritude became larger yesterday (~0.15mag).
We are planning to take 5 hours run tonight.
To comfirm the periodicity, follow-up observations are strongly encouraged.

R. Ishioka, M. Uemura, K. Matsumoto, Hidetoshi Iwamatsu, 
and  T. Kato at Kyoto
