Comet C/2017 T2 was discovered on October 2nd 2017 by Pan-STARRS 1 telescope (Haleakala). By the time of discovery it was 19.9m.. Recent observation (Manzini et al., 2020) with the 1.82m Copernico telescope (OAPD-INAF) of the Asiago Astrophysical Observatory (MPC 098, Italy) on 29.85 April 2020 reveal some circular structures, concentric to the comet’s optocenter. This finding may be suggestive of a strong activity modulated by a rotation of the nucleus with a spin axis directed towards the Earth in this period. At the time of writing this C/2017 T2 (PANSTARRS) was in the constellation of Ursa Major with a visual brightness of 8.3 mag. The image taken in IRIDAObservatory on 23th of May 2020 at 20:30 UTC, shows the comet in a close visual encounter with the galaxies M81 and M82. We were surprised because there is an evidence of a fine anti-tail visually pointed forward.
