C/2020 O2 Amaral
more info
Comet C/2020 O2 was discovered on 23 July 2020, more than one year before its perihelion passage. In the moment of orbit determination, this comet was still observed.

Currently, solutions (GR and NG) based on pre-perihelion data are given. Therefore, the data arc span over 1.10 yr in a range of heliocentric distances from 5.76 au to 4.86 au.

This is Oort spike comet.
