LETTER - Replying to Mike Read’s letter, Star April 10, the object he saw accompanying the International Space Station could have been a secondary reflection in the human eye lens, like sunlight in a raindrop.
I saw the spacecraft but it looked like a single elongated object, probably due to a astigmatism in one eye.
If the double image was due to an accompanying object, it is interesting to work out what its actual separation was in yards, assuming the craft was 200 miles up and the minimum angular separation by sharp eyesight to be about one minute of arc (about 1/30 the angular diameter of the moon). The answer comes to 90 yards.
Perhaps Ray Otterhead could ask his NASA friend to send details of the spacecraft’s size and structure?
