    High-resolution spectroscopic imaging of the Sun with a universal birefringent filter and a Fabry-Perot Interferometer

    We describe an optical device consisting of a Universal Birefringent Filter and a Fabry-Perot interferometer used in tandem to obtain monochromatic images of the Sun in the visible spectrum (between 4200 and 7...

    H and K (Ca II) emissions as observed in coronal spectrum in the July 20, 1963 solar eclipse

    From a detailed analysis of a coronal spectrum taken from a DC-8 jet airplane during the Eclipse of 20 July, 1963 a rough model of a coronal cold region (T ≈ 105 K) has been obtained.

    Isodensitometric analysis of flare on 1966, March 20

    We describe the behaviour of the McMath A.R. No. 8207 from the photometric point of view during the remarkable flare of 20 March, 1966. The results of the photometry are compared with the radio and Ly-α emission.
