Telescopic comet ATLAS - 16.4.2020 at 23.44 - 17.4.2020 at 01.33 Hankasalmi, Murtoinen Observation number 90036

Visibility II / V

Harri Kiiskinen, Jyväskylän Sirius

The main focus of the evening was C / 2019 Y4 (ATLAS), which has broken down into several parts. The two brightest fragments I got visible, but unfortunately not dimmer. There were minor technical challenges with Autofocus. Thanks again to Arto for technical support at an inhumane time.

edit: added Figure 6
