We report our new analysis of Oort-cloud comet C / 2020 T2 (Palomar) (T2) observed at 2.06 au from the Sun (phase angle of 28. ◦ 5) about two weeks before perihelion. T2 lacks a significant dust tail in scattered light, showing a strong central condensation of the coma throughout the apparition, reminiscent of so-called Manx comets. Its spectral slope of polarized light increases and decreases in the J (1.25 µ m) and H (1.65 µ m) bands, respectively, resulting in an overall negative (blue) slope…
