About this image

This a plot of the pixel values for a slice parallel to the tail direction which cuts through the brightest pixel. Three dates are shown: 2020 March 31, April 5 and April 6. All are of the same scale and obtained in conditions of very good transparency with a system resolution of 1.29 arcsec/pix. The peak brightness is falling and the width of the coma is increasing. This is consistent with a significant fragmentation of the nucleus.
