Count Rate Plots, per Solar Rotation, on Microfilm


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

Time span: 1967-05-24 to 1969-04-25


This data set consists of cosmic-ray telescope (proton and electron) count rates plotted on one reel of 35-mm microfilm. The data plots include the telescope sensor combinations that correspond to the following energy intervals for protons: 0.8 to 9.6 MeV, 9.6 to 18.8 MeV, 29.5 to 94.2 MeV, and 94.2 to 170 MeV. The 16 plots cover the time interval from solar rotation numbers 1831 (May 24, 1967) through 1856 (April 25, 1969). In addition, five plots of E1 electron telescope values, for solar rotation numbers 1831 to 1835 (May 24, 1967, to October 6, 1967), and five plots of E2 values, for solar rotation number 1831 (May 24, 1967, to June 20, 1967), are included. Each plot gives the count rate (logarithmic) vs time (day number) for one solar rotation.
