The problem of atmospheric-aerosol-induced aureole effects in astronomical observations of the solar corona is considered theoretically and by analysis of sample data obtained at Sacramento Peak Observatory. Both conventional solar-telescope and coronagraph observations are examined in terms of spectral coverage, spatial resolution, and instrument speed; effects due to the angular size of the sun; and the phase effect of forward scattering on the flying aerosol particles. Graphs, sample images, and a calculated atmospheric-transmission profile based on the AFGL standard model are provided, and the implications of the analysis for image-processing methods are briefly indicated.
