Abstract

The preliminary results of the solar CCD observations of the Balmer and Pashen continua and of the Balmer precontinuum are presented. The Balmer precontinuum intensity distribution for the emission features of a.r. 7890 NOAA/USAF are obtained. The limits of electronic concentration in the plasma volume along the line of sight are evaluated for an emission feature from this a.r. Solar monitoring at the hydrogen series continua and precontinua appears to have considerable promise.
