    Adam, I would be surprised if the Sky didnt allow for solar
    illumination of a satellite. Perhaps you haven't set in on somehow.
    If satellite tracker is meant for mainly radio tracking it is
    to be expected that solar illumination isnt so important.
    I dont have a copy of either programme so I cant
    test them
      out. However Skymap pro (v8) which I do use
    agrees with HA in saying the entire pass was in
    shadow.
