โœฆ Synopsis

Anew series of photometric observations of the H and K lines were obtained at Sacramento Peak Observatory in 1964 and 1965. In both the observations and the data reduction special attention was given to obtaining a suitable average over the solar fine structure and to defining a proper reference continuum. The results are that the central intensities of H and K are the same and equal to 4.2 % of the continuum. The limb-darkening curves at the line centres are also the same for both lines.

A series of non-LTE radiative transfer solutions for Ha was computed using the integrodifferential equation technique of Athay and Skumanich (1967). A model hydrogen atom consisting of three bound levels and a continuttm was assumed. It was found that increasing the temperature of the chromosphere a
