CBET 4761 & MPEC 2020-H220, issued on 2020, April 28, announce the discovery of a comet (magnitude ~16.5) by Theodore A. Pruyne on four 30-s CCD exposures taken with the Catalina Sky Survey's 0.68-m Schmidt telescope. The new comet has been designated C/2020 H2 (PRUYNE).We performed follow-up measurements of this object while it was still on the PCCP webpage.Stacking of 55 unfiltered exposures, 10 seconds each, obtained remotely on 2020, April 27.4 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 1' arcmin in diameter.Our confirmation image (click on it for a bigger version)MPEC 2020-H220, assigns the following preliminary parabolic orbital elements to comet C/2020 H2: T 2020 Apr. 27.62; e= 1.0; Peri. = 26.76; q = 0.83; Incl.= 125.04by Ernesto Guido, Marco Rocchetto & Adriano Valvasori
