Comet C/2020 F7 (LEMMON) observed while it was mentioned on the PCCP and observed on 11 may 2020 from my backyard observatory with 0.4-m f/3.8 reflector. I could confirm the cometary appearances of this object. Later this object was assigned as comet C/2020 F7 (LEMMON) via MPEC 2020-K107 and CBET 4777 : 20200521 : COMET C/2020 H7 (LEMMON) issued on 21 may

                                      COMET C/2020 H7 (Lemmon)                         

     This object was reported on Apr. 29 as a possible NEO candidate by G. J. Leonard on behalf of the Mount Lemmon Survey (G96), without any mention of cometary activity.  Below are reports of cometary features:
