This star is brightening after an almost 3 year minimum. I recorded it last night 20181015.537 at 16.2. Very faint but definitely visible.

Ok will take images for a while and then see. Have been recently at a conference on hydrogen deficient stars due to the fact that the organizer stumbled across my data on V348 Sgr (one of the few hot R CrB's) and invited me to present a poster as he was impresssed about the data.
I have nearly 2 month of data and see quite some variation in magnitude in I and V. The B magnitude is too low so I will switch so R instead.
Data are with the AAVSO database.
Thanks, Josch, for following this star. Are such variations common in hot R CrB's? I have not noticed this ni other RCBs I observe. eg S APS, W MEN.
is this a hot R CrB star? I follow one (V348Sgr) and there is large variation. To my knowlegde there are only 5 hot R CrB's known. This knowlegde I learned from the HDEF2018 conference in Armagh, where I had a poster about this star.
Josh, please ignore the reference to it being a hot RBC. I misread a reference.
