We performed follow-up measurements of this object while it was still on the PCCP webpage.
Stacking of 16 unfiltered exposures, 90 seconds each, obtained remotely on 2020, July 27.05 from X02 (Telescope Live, Chile) through a 0.6-m f/6.5 astrograph + CCD, shows that this object is a comet with a diffuse coma about 8" in diameter (Observers E. Guido, M. Rocchetto, E. Bryssinck, M. Fulle, G. Milani, C. Nassef, G. Savini, A. Valvasori).
MPEC 2020-P10, assigns the following preliminary parabolic orbital elements to comet C/2020 O2 (Amaral): T 2021 Aug. 23.84; e= 1.0; Peri. = 9.39; q = 4.90; Incl.= 71.89
Congrats to Leonardo Scanferla Amaral (Observatório Campo dos Amarais, OCA) for this discovery! This is the fourth amateur comet discovery of 2020.
