Please see my other image of comet C/2019 Y4 ATLAS. This image was taken the next night on April 09. It again shows that the comet has an elongated nucleus within the blue/green coma, which is a sign of impending break up of the comet. The comet's disintegration into multiple fragments was subsequently captured by the Hubble Space Telescope on April 20, 2020. Here, the comet is traversing a starry field in the constellation Camelopardalis. In addition to the elongated nucleus within the blue/green coma, there is a faint dust tail trailing behind the comet which exhibits a slight reddish tinge.
