A solar eclipse offers a unique opportunity to study the effects of the rapid disappearance and reappearance of solar thermal and ionization radiations on the ionospheric production, loss, and transport processes which affect the total ionospheric number density. Polarization measurements utilizing beacon emissions of the ATS-3 satellite were supplemented with bottomside ionospheric observations made near the subionospheric point during the partial eclipse of 10 Jul 1972. Time variation of the total electron content from 1100 to 1730 EST during the eclipse day and during the two days prior to and the three days following it are shown. A comparison of polarization changes during the eclipse day obtained at Fort Monmouth and at Sagamore Hill Radio Observatory, Hamilton, Mass. is given.
