Sky maps of the number of detectable satellite trails (a) and effect on the observations (b), for all the satellites from Table 1 on a FORS2 image (6′ field of view, 5 min exposure time) on Paranal ( latitude) at equinox. The circles indicate elevations 0°, 10°, 30°, and 60°. The legend of each plot gives the Sun elevation and the average number of trails (a) and the losses they cause (b) for observations above 30° elevation All satellites are brighter than the detection limit and none is bright enough to cause heavy saturation.
