Maps of the sky above Paranal from twilight until mid-night; the color scale indicates the number of satellite trails crossing an X-shooter 10"-long slit during a 1000 s in that direction in the sky; the text in the figure indicates that the simulations were performed for the VLT (at latitude −24.6°) for X-shooter with a slit of 10 ×1" and an exposure time of 1000 s (top left text); the constellations used for the simulation include 401 849 satellites from Starlink, OneWeb, Guo Wang, Amazon Kuiper, and E-Sat (top right). The bottom-left text gives the local time and the declination (0°) and elevation of the Sun (from −12° to −54° with a step of 6°, and for mid-night at a solar elevation of −65°; finally, the bottom-right text indicates that the absolute magnitude of the satellites is set to V1000km = 6, and gives the conversion into visual (in the range [9.3, 3.6]) and effective magnitudes (in [23.2, 17.7] for this geometry).
