Used softwares ASTROMETRICA Resulting picture sampling (scale) 1.65 "/pix Image processing Prism and Gimp Remarks or comments Probable 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. Observation submission date 2020 Apr 11 01h35m27s Observation modification date 2020 Apr 11 10h51m14s
