Stellar occultations by the Huya system observed on (a) 2021 March 28, (b) 2023 February 17, and (c) 2023 June 24, as analyzed in this study. Positive chords are presented by solid lines in colors with error bars in red segments. Close negative exposures are presented by darker-green segments, and other negative data sets are presented in light-green dashed–dotted lines. Inconclusive results are represented by dotted gray lines. The blue star marks the Huya predicted position on 2023 February 17. The black ellipse is the best solution for the primary, and the shadow region represents the 1σ uncertainty. Dotted and dashed circles show the solutions for the satellite detections (see text). The black arrow shows the direction of the shadow movement.
