On early June, the astronomical twinlight has began. The satellites are now partially visible toward the South horizon, because the Earth shadow is rather low, inducing their extinction when they are near the horizon. By studing where they disappear, it is possible to draw the Earth shadow arch. This arch is drawing in the following picture.
Don't miss the video (gathering 517 photos and spanning 2 hours) from which this picture is created: click here. You'll see how the number of visible satellites is increasing during the astronomical twilight! |
