Position end figures 43s.32, 19".2 measured with 0.50m reflector + CCD at Skygems Observatory, Namibia. J2000, Gaia DR2 positions. Position appears to correspond to a 19.7 G magnitude star (Gaia DR3 4136619720186379264) which appears to be the same as a 20.8 g magnitude star measured in Pan-STARRS PS1 survey (Star ID 88552619307433951). Approximate unfiltered magnitude 13.0 using APASS R mag comparison stars. Andrew Pearce, Nedlands, Western Australia.
