MPEC 2020-U254 : COMET C/2020 U3 (Rankin)

D. Rankin reports the discovery of a comet in exposures taken Oct. 22 UT by Mt. Lemmon Survey (G96).  He reported a very condensed 5" coma and a straight 7" tail in position angle 95 deg.  R. Weryk found prediscovery observations going back to Sept. 7 and additional prediscovery astrometry was found in the isolated tracklet file.  

Additional reports of cometary features are as follows:
