Saturn Encounter


Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1979-08-23 to 1979-09-05


These data, supplied by the experimenter, consist of images obtained during the Pioneer 11 encounter with Saturn. The images encompass days of year (DOY) 237-248, 1979. Most of the images are faint, or distorted, or have many lines of missing information. The best frames among these are F35A, showing atmospheric structure of Saturn, polar hood, and the rings well. F12B is good for the ring structures, showing the rings only. Good images among the negatives are F37 (blue), F33A, F33R (red), F19.5B+R, and F12B and R. The best images among the color are F37, F33, F19.5, and F12 (The connotation of letters F and G carried on the scheme of designating approach and recession to Saturn as to Jupiter previously). The information block on the stereo pairs gives range, phase central point latitude, start and stop times of exposure sectors, filter used, and data processed. The best stereo pairs are F37, F32, F12 (for rings), F19.5, and F33. Accompanying the photos is a partial listing of the photos with a brief description of features visible and a complete listing which gives the following information: (1) frame number (image seq. No.), (2) midtime in DOY, h, min; (3) range in km; (4) pixel size in km, (5) phase angle in degrees; (6) latitude; (7) local central meridian (LCM) and (8) a "not displayed" code. The "not displayed" code is explained separately.
