Peculiar solar flares and plages of possible interest for the study of electric quadrupole lines of NaI and Mgii

  • Y. Öhman


Attention is drawn to flare-like plages showing the resonance lines of Nai and Mgii as strong emission lines. Spectra of such objects may prove of interest for the study of electric quadrupole lines of the type 32S-n2D.
