C/2020 F2 ATLAS
more info
Comet C/2020 F2 was discovered on 21 March 2020, more than three years before its perihelion passage. Later a series of pre-discovery observations were found going back to 27 May 2019 (heliocentric disctance: 10.96 au). In the moment of orbit determination, this comet was still observed.

Currently, GR solution based on pre-perihelion data are given. Therefore, the data arc span over 3.13 yr in a range of heliocentric distances from 10.96 au to 8.82 au.

This is Oort spike comet.
