Abstract:
The Institute for Astronomy's Eclipse Spectrograph was used to obrain prominence and coronal spectra throughout the wavelength range from about Lamda Lamda 3500-7000 at the February 16, 1980 total solar eclipse. The observations were made at the Japal-Rangapur Observatory near Hyderabad. The spectra will be analysed to determine the temperature, density and composition of the prominence plasma, and will also provide tests on recently developed non-LTE, multi-atom theoretical prominence models. Analysis of thet forbidden line coronal spectrum too will yield diagnostic data for the coronal plasma.
