With an observation arc of seven months the orbital period of the comet is estimated to be 434 years. An eccentricity of 0.996 gives the comet a semi-major axis (average distance from the Sun) of about 57 AU which is comparable to the average distance of Eris at 68 AU. The comet will not leave the Solar System and will come to aphelion (farthest distance from the Sun) in 2227. The comet was spotted with averted vision by 26.8K 191 3166 527was spotted with averted vision by Piotr Guzik as a starlike object on 8 September when it had an estimated magnitude of 4.7. The comet tail was 3.5 degrees long when imaged with CCD. On 12 September 2023 the comet passed 0.84 AU (126 million km; but was only 15 degrees from the glare of the Sun. Then on 17 September 2023 it will come to perihelion 0.22 AU from the 26.8K 78 million mi; 330 LD) from Earth 191 3166 Sun. The comet will be briefly in the evening sky in mid September
