Dear colleagues, I have just finished analysing my unfiltered CMOS observations of TCP J17321088+0807243 obtained on 2023, Jun 15/16 and June 16/17 at CBA Belgium Observatory using a 0.40-m f/10.0 telescope and QHY-268M CMOS camera under clear skies. My observations were triggered by Taichi Kato's post in vsnet-alert 27850.
