An apparently asteroidal object of 19th magnitude was found in Mt Lemmon Survey images taken with the 1.5m reflector on 7 September 2018. It was placed on the PCCP as ZRBBF83 and follow up observations by astrometrists showed that it was slightly diffuse and elongated. With a preliminary orbit, Gareth Williams was then able to find pre-discovery PanSTARRS images from August 2018. Date 10x10 mag Error Kphot mag Coma ' 10-Oct-18   19.77   0.04   19.6   0.2
