Chords measured during the 8 August 2020 event show the detection of MS4’s limb in blue with 1σ error bars (red segments). Six positive chords with large error bars were suppressed from this plot for better visualization: TAROT, Lleida, Khmelnytskyi, Fuensanta de Martos, Kharkiv T36, and Marbella. The green lines represent positions compatible with the total target’s flux within the noise (i.e., no secondary occultation). The order of positive chords, from north to south, is the same as in Table 3.
