โœฆ Synopsis

Unusual and intense emission in the DI, D2 lines has been registered photoelectrically in an undisturbed region near the center of the solar disk on 28 July, 1966. Various aspects of the possibility that the emission might originate in either artificial or natural comets by processes of resonance scattering or flu orescence have been analyzed. It is shown that the observed emission can only be located on the solar surface. Some aspects of the problem are discussed briefly.
