tacking of 20 unfiltered exposures, 90 seconds each, obtained remotely on 2022, April 2.4 from X02 (Telescope Live, Chile) through a 0.61-m f/6.5 astrograph + CCD, shows that this object is a comet with a compact coma about 9" arcsecond in diameter (Observers E. Bryssinck, M. Rocchetto, E. Guido, M. Fulle, G. Milani, G. Savini, A. Valvasori).

CBET 5112 assigns the following parabolic orbital elements to comet C/2022 F1 (ATLAS): T 2022 Sep. 4.00; e= 0.99; Peri. =  281.10; q = 5.94 ;  Incl.= 57.98; adding that: "these suggest that the comet will pass 1.46 AU from Saturn in 2025 August".
