    (This replaces MPEC 2022-E46 -- observation details were missing.)
     R. A. Kowalski reports the discovery of a comet in four 30-second survey 
images taken on Feb. 25 UT by Mt. Lemmon Survey (G96), noting a very condensed
10" coma. Prediscovery positions were reported back to Jan. 2022. Additional 
reports of cometary features are as follows:
