Near infrared photographs of the solar corona were made at sea level from a ship, Canberra, positioned about 300 miles west of Nouakchett, Mauritania. Polarimetry was obtained by taking exposures through HR plane polarizing filters oriented at three successive 60 deg intervals. Kodak 2424 Aerographic infrared film was used. The pass band of the filter-film combination was about 90 nm centered around 840 nm. The inner corona was occulted by a disk placed 1.5 m in front of an f/2.9, 230-mm-focal-length, Dallmeyer lens. One complete set of frames was obtained which shows changes in streamer structure with changing filter orientation. On the frame with the polaroid's axis of transmission almost parallel to the north solar axis, four outer coronal streamers to the west can be followed and two broad diffuse streamers to the east where they merge into a single blur. A broad, diffuse illumination is also visible to both east and west.
