                     COMET C/2023 V4 (Camarasa-Duszanowicz)                     

     S. Deen reports cometary activity of an asteroidal NEOCP candidate
(first reported by Moonbase South Observatory - L87 on Nov. 5 UT) in follow-up
images taken on Nov. 5 UT by Deep Random Survey (X09), noting a condensed 2".8
coma and a curved 8" tail at position angle 10-35 deg. Additional reports 
of cometary features are as follows:
