Relative albedo map distribution derived with ADAM. The bright region visible in the images of 2018 (Fig. A.1), called Panthia in Viikinkoski et al. (2018), is visible around longitude ∼ − 60° in the north hemisphere. Other albedo features visible in multiple images of the 2019 apparition include one bright spot on 28 July 2019 and 6 August 2019 at (longitude, latitude) = ∼(−60° , − 10° ) and two bright spots on 5 August 2019 at ∼(120° , − 15° ) and ∼(160° , − 10° ).
