A possible comet of 19th magnitude was found in images taken with the Zwicky
Transient Facility camera on the 1.2m Oschin Schmidt on 26 July 2019. It was placed
on the PCCP as ZTF055N. It has a nearly perpendicular parabolic orbit. JPL classed
it as a Parabolic Asteroid. No cometary activity was detected until May 2020, when it
was observed by the 3.6-m Canada-France-Hawaii Telescope on Mauna Kea and
then confirmed by several other observers. It was redesignated as a comet in July
2020.
