COMET P/2020 O1 (LEMMON-PANSTARRS)

     R. Weryk, Institute for Astronomy, University of Hawaii, reports the discovery of another comet in three 45-s w-band images obtained with the Pan-STARRS1 1.8-m Ritchey-Chretien reflector at Haleakala on July 20 UT, the object then showing a diffuse 0".5 coma (full-width-at-half-maximum size about 1".94 in 1".48 seeng) with an obvious straight tail extending for > 8" toward p.a. 245 degrees (tail partially obscurred by star).....(Snip)

 .....  E. Bryssinck writes that twelve stacked 120-s exposure taken remotely by a large group of observers on July 28.2 with a "Telescope Live" 0.61-m f/6.5 reflector at Rio Hurtado, Chile, show a central condensation with a 9" coma and a hint of a tail about 12" long in p.a. 232 degrees; the magnitude was measured as 20.2 in a radius of 5"....
