Experiments on the OV1-18 satellite measured the energetic solar particle fluxes and the auroral particle fluxes during the Polar cap absorption event which began on 2 November 1969. The satellite observations were coordinated with the DASA PCA-69 rocket measurements at Fort Churchill, Canada. On the nightside near 0300 hours L.M.T., Fort Churchill was poleward i.e., inside the polar cap of the le cutoffs for 2-MeV protons throughout the event. On the dayside near 1300 hours L.M.T., Fort Churchill was near the le cutoffs for 2-MeV protons, being at times poleward and at other times equatorward of the cutoffs. Dayside and nightside energy distributions for solar flare electrons, protons, and alpha particles are presented for the magnetic latitude of Fort Churchill. The energy distributions for the solar flare electrons, protons, and alpha particles and the observed temporal variations of these particles during the event are presented for the polar cap region. Auroral electrons were observed at or near the Fort Churchill magnetic latitude on every dayside and nightside overpass. The auroral electrons contribute significant ionization to the D-region below 92 km. Author
