The Solar Corona covers the proceedings of the International Astronomical Union Symposium No. 16 held at Cloudcroft, New Mexico, U.S.A. on August 28-30, 1961. The book focuses on the characteristics, reactions, and analysis of the solar corona. The selection first offers information on the local physics of the corona and comments on coronal heating. Discussions focus on density, temperature, energy balance, excitation and ionization, and electrostatic ejection of light ions. The text then takes a look at the temperature of the solar corona and relative populations of Fe in the corona. The publication tackles excitation of the red and green coronal lines; filamentary structure of the solar corona; prediction of solar emission lines in the short-wave region of the spectrum; and prominences of the solar corona. The text then examines the study of the corona by radar, rockets, and satellites; slow variations of the solar corona; and influence of flares on the associated permanent coronal condensation. The selection is a vital source of data for scientists and readers interested in the solar corona.
