The May Day party continued at the Taurus Hill Observatory, when three comets were spotted on 1 – 2 May 2021 at 00.35-02.00 Finnish time: C / 2020 R4 (ATLAS), C / 2020 T2 (Palomar) and C / 2017 K2 (PANSTARRS).
In the pictures, the north is at the top and the east is on the left. The image field is approximately 11′ x 15′ in size. Negative images show the size of the comet better. The tail of the C / 2020 R4 (ATLAS) comet is quite long, fits barely in the picture. A C14 ″ telescope, SBIG ST-8XME camera and photometric R-filter were used for imaging. The shutter speeds in the sum images are Atlas 15 x 60s, Palomar 10 x 90s, and PANSTARRS 10 x 120s, respectively.
