    Hi Ted and list,
    
    I asked the designer of the satellite the reason for the black colour of the
    body. He told me it was to keep the interior at a convenient temperature for the
    electronics inside. Even the inside is painted black, except for the instrument
    platform that is aluminum honeycomb covered with Kapton tape.
    
    As for positional measurements, the emphasis has now been placed on flash rate
    measurement. For obvious reasons, positional data would not be of great
    scientific value. But the flash rate is important to determine the effects of
    Eddy currents created in the satellite shell on its spin rate. This will help
    design the respin system for future Starshine sats. Here is a link to the
    Starshine page giving the instructions for beginners on how to measure and
    report the flash rate http://www.azinet.com/starshine/flash_rate.html
