The Chromospheric Continuum Observed at the Total Solar Eclipse of 12 November 1966 and a Model of the Low Chromosphere
Abstract
We have obtained the Balmer continuum and the continuum at 40O0 in the chromosphere by observing the total solar eclipse of 12 November 1966. These data are in good agreement with those of previous eclipses. Existing chromospheric models are compared with comments. By using this eclipse data and the continuum at 6900A observed by MAKITA (1971) at the total solar eclipse of 7 March 1970, we have constructed a model chromosphere, which can explain the eclipse observations and also the observations of UV and mm radiation. In our model the distribution of hydrogen density is equal to that of the NOYRs and KALKoFEN (1970) model. The electron density and temperature lie between those of the NOYRs and KALKoFEN (1970) model and of the ATHAY and CANFIELD (1970) model, respectively. Key words: Chromospheric continuum; Model chromosphere; Solar eclipse.
