SOUP
The Solar Optical Universal Polarimeter (SOUP) experiment was flown in July and August 1985, on board the STS-51F/Spacelab II shuttle mission. Images of solar features observed in white light were recorded on film. The targets were solar pores, sunspots, upwelling, active region AR 4682, and the structures along the solar limb. When the film was returned to the investigator team and developed, it was digitized frame by frame.
