Stacking of 15 luminance-filtered exposures, 60 seconds each, obtained remotely (in poor conditions, high clouds) on 2022, May 6.4 from X02 (Telescope Live, Chile) through a 0.61-m f/6.5 astrograph + CCD, shows that this object is a comet with a diffuse coma of size about 12" and magnitude of 18.3-18.9 in an aperture radius of 5".5 (Observers E. Bryssinck, M. Rocchetto, E. Guido, M. Fulle, G. Milani, G. Savini, A. Valvasori).

CBET 5121 assigns the following parabolic orbital elements to comet C/2022 J1 (Maury-Attard): T 2022 Feb. 21.59; e= 1.0; Peri. =  307.65; q = 1.63 ;  Incl.= 106.45 (It is possible that the comet has a periodic orbit on the order of 120 years or so).
