Since then, I have been observing satellites more frequently. Unqoute. The entering of a satellite into the earth shadow does depend on the height of the satellite, think of the moon; the latitude of the observer and of course the time of year, for polar regions there's no shadow in the summermonths. At my latitude, 52 degrees north, the earthshadow is low in the south in the summer. In winter it rises more and more and two hours after sunset the part of the sky south of zenit is "in shadow".
