COMET C/2022 T1 (Lemmon)
T. Prystavski reports cometary activity of A/2022 T1 (initially reported
by Mt. Lemmon Survey (G96) on 2022 Oct. 29 UT) in five 120-second images
taken from a roving location (247) on Feb. 1 UT, noting a very condensed
6" coma and a straight 8".4 tail at position angle 310 deg. R. Weryk reported
a very condensed 0".7 coma and a broad 4" tail at position angle 300-350 degs.
in four 45-second Pan-STARRS 2 (F52) images taken on Jan 18 UT.
