  • Disappearing solar filaments and geomagnetic activity 
    Sastri, J. H (Springer, 1986-05)
    As a sequel to the recent identification of the high-speed stream as the candidate structure in the solar wind at 1 AU that is primarily responsible for the geomagnetic disturbances occasionally noticed after 'disparition ...
  • Poleward migration of the magnetic neutral line and the reversal of the polar fields on the sun. I - Period 1945-1981 
    Makarov, V. I; Fatianov, M. P; Sivaraman, K. R (Springer, 1983-06)
    Poleward migration of the magnetic neutral line on the sun has been calculated for the periods 1945-1950 and 1955-1981 using synoptic charts based on H-alpha observations. Epochs of sign reversal of the solar magnetic field ...
  • Temporal behaviour of pressure in solar coronal loops 
    Sasidharan, K; Sreedharan, T. D; Pratap, R; Krishan, V (Springer, 1995-03)
    The temporal evolution of pressure in solar coronal loops is studied using the ideal theory of magnetohydrodynamic turbulence in cylindrical geometry. The velocity and the magnetic fields are expanded in terms of the ...
  • Time structure of solar decametre Type III radio bursts 
    Thejappa, G; Sastry, Ch. V (Indian Academy of Sciences, 1982-06)
    The time structure of solar radio decameter Type III bursts occurring during the periods of enhanced emission is investigated. It is found that the time profiles can take a variety of forms of which three distinct types ...
  • Time-resolved spectral observations of spicule velocities at several heights 
    Hasan, S. S; Keil, S. L (American Astronomical Society, 1984-08)
    The vacuum telescope of the National Solar Observatory, Sacramento Peak was used to obtain H-alpha spectral observations of spicules. A set of spectra corresponding to five slit positions above the solar limb were recorded ...
