Telescopic comet ASASSN, Orimattila, Artjärvi, Tähtikallio

The comet C / 2018 N2 (ASASSN) was filmed on the first night of the October 2020 work. The comet was discovered by the "All-Sky Automated Survey for Supernovae" (ASAS-SN) search program from July 8-11, 2018 images. The comet is on a hyperbolic orbit and is already leaving the solar system and continues to dim. We’ve filmed it earlier on the second night of the January 2020 work. When photographing the comet was 4,570au away, the nearest 2,1957au on October 20, 2019. 1Picture. stacked Average by comet.
