Remarks or commentsProbable disintegration of the pseudo nucleus of comet CK19Y040. On April 09.83 condensation (CK19Y04b) in PA : +/-275°, distance +/-11" from the mother core, Magnitude of +/-16.5T for an opening radius of 3.3". As of April 10.83 condensation (CK19Y04b) in PA : +/-285°, distance +/-14" from the mother core, Magnitude of +/-16.5T for an opening radius of 3.3". The parent nucleus appears to have a debris path of +/- 25" in length. There seems to be a debris path of at least 4 components with the parent nucleus included in this addition.
