Millstone Hill incoherent scatter observations of the ionospheric response to the solar flare of 7 August 1972 /

The Millstone Hill incoherent scatter radar was in operation during the important 3B solar flare which occurred at 15:00 UT on 7 August 1972. Measurements of the electron density profile were made over the height range of 125 to 1200 km, together with observations of the electron temperature, ion temperature, and vertical drift velocity above 225 km. The ionospheric Ne(h) profiles obtained span the largest height range ever studied during flares, while the temperature and drift data represent the first measurements of these parameters ever made under flare conditions. In discussing the overall results obtained during this event, estimates are made of the flare-induced electrodynamic and thermal processes which contribute to the observed effects.
