Stacking of 25 luminance-filtered exposures, 60 seconds each, obtained remotely on 2022, June 9.3 from X02 (Telescope Live, Chile) through a 0.61-m f/6.5 astrograph + CCD, shows that this object is a comet with a condensed coma of size 11", with magnitude 19.5 as measured in a circular aperture of radius 5".5, with no clear tail visible (Observers E. Bryssinck, M. Rocchetto, E. Guido, M. Fulle, G. Milani, G. Savini, A. Valvasori).
CBET 5134 assigns the following parabolic orbital elements to comet C/2022 L1 (Catalina): T 2022 Sept. 28.10; e= 1.0; Peri. = 59.74; q = 1.59 ; Incl.= 123.46
