Brian Africano discovered a comet of 18th magnitude in Mt Lemmon Survey images
taken with the 1.5m reflector on 27 November 2018. It was discovered at almost the
same time by Hannes Groeller in images taken by the Catalina Sky Survey with the
0.68m Schmidt on 27 November, but his report arrived after the one from Mt
Lemmon. The object was placed on the PCCP as ZW8B74D.
