Post-occultation map of the stellar occultations observed on July 26, 2020, from South Africa and South America (upper panel) and on February 24, 2021, also from South America (lower panel). Solid blue lines and black dots indicate the observed shadow path every minute, and the largest black bullet represents the closest approach instant. The arrow shows the shadow direction over the Earth’s surface. Blue dots show the positive detections, green triangles show the negatives and white diamonds show the stations with bad weather conditions or technical problems.
