    Results/More Information

    Magneto-optical disk with digital video recording of observations (no less than 10 minutes per one session) returned for analysis. Ballistic data for control of measurement results, including ISS attitude and altitude, geographic coordinates of a subsatellite point, angle of the Sun and angle of the Moon must also be transmitted. Original and decoded telemetry information on equipment state, operational modes and detected events of lightning.
