This comet continues to do interesting things! My image tonight shows a new fragment 20 arcsec west and 9 arcsec south of the the main nucleus (component B). The new fragment is around mag 18.8. The residual nucleus, component B, is currently around magnitude 15.2. An image showing the fragment is here: http://www.nickdjames.com/Comets/2020/2019y4_20200502_2124_ndj.jpg Has anyone else imaged this? Nick.
