The prominence on the west limb.
Spectra of H-alpha, beta, He D3, Ca2K, and Ca2H lines were obtained by locating the slit at the selected two positions on the prominence. Extra-long exposure time was employed for the spectral observations in order to diagnose the physical state of the very faint structures including the prominence-corona transition region. |
