COMET P/2022 R1 (PANSTARRS)
R. Weryk reports the discovery of a comet in four 45-second w-band survey
images taken on Aug. 1 UT by Pan-STARRS 2 (F52), noting a condensed 0".9 coma
and a straight 3" tail at position angle 270 deg. Prediscovery positions were
detected from Pan-STARRS 1 and 2 since Jun. 2022. Additional reports of cometary
features are as follows:
