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. This image was taken at IRIDA Observatory on July 9th 2020 at 21:30 UTC. The strange position of the comet's nuclei is obvious (see mouseover). It is due to the fact that when viewed from Earth, the dust and the ion tails of the comets are superimposed.
