CBET 5121 & MPEC 2022-J88 , issued on 2022, May 11, announce the discovery of a comet (magnitude ~18) by A. Maury and G. Attard on images obtained with a 0.28-m f/2.2 Schmidt reflector at San Pedro de Atacama, Chile, on May 5. The new comet has been designated C/2022 J1 (Maury-Attard).
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).
