Proposal

I propose periodical observations of AF Psc known as Bond´s flare star, which has just 143 AAVSO observations, and all of them are visual. The star has valuable UV excess and shows fast mini flashes with amplitude 0.02-0.05m and brighter flashes 0.2-0.5m with periodicity of some days and duration of 5-10 min. Chanse to detect Bond´s megaflare is almost zero, but serial observations may imrove data of TESS and Kepler.
Due to short flashes duration observations with FSM short exposures in B are preferable. I propose to make 0,5-1 h serias per 2 weeks during 6 months in order to Bond´s flare star monitoring.
