COMET P/2020 S5 (PANSTARRS)
R. Weryk reports the discovery of a comet in exposures taken on Sept. 21 UT
by Pan-STARRS 1 (F51), noting a 0".9 coma and 4" tail at PA 225. Prediscovery
detections going back to Aug. 26 were later reported by Mount Lemmon Survey
(G96). Additional reports of cometary features are as follows:
