The picture is assembled from two single 60-second pictures and it shows two traces separated by the 11 seconds downloading time from one picture to the other. The interesting feature of this image is that the object flashed in the sunlight with a quite high frequency and it showed two levels of intensity. It is the debris of an Ariane 4 rocket which launched the US telecommunications satellite Galaxy 7 into geostationary orbit in 1992. The rocket body itself has already decayed.
