Telescopic comet ATLAS - 24.4.2020 at 23.07 - 24.4.2020 at 23.31 Imatra Observation number 90214

Visibility II / V

Rauno Päivinen, Etelä-Karjalan nova

Comet C / 2019 Y4 (ATLAS) photographed on the evening of 24.4. The comets broken into the comet were no longer noticeable on my devices. I also watched this visually after the shooting session on the C14 and at first I had trouble even distinguishing the whole comet. The surface brightness did not differ much from the background and no core of any kind was visually visible. Shooting time should have taken a little later, but the approaching clouds forced us to act quickly.
