Abstract : The analysis of data obtained previously during the solar eclipse of November 12, 1966, in Cassino, Brazil, was completed. The next major activity was the successful development and flight of the Lyman-alpha headlamp experiment to make direct measurements of nitric oxide density. A rocket experiment to measure the effects of supersonic velocity on probe measurements was performed on October 13, 1970, at night at White Sands Missile Range. The data showed that very large errors can be introduced by supersonic velocities. A synoptic program to study the variability of mesospheric ionization, particularly in winter, involved rocket measurements at White Sands Missile Range.
