  • Evolution of latitude zonal structure of the large-scale magnetic field in solar cycles 
    Makarov, V. I; Sivaraman, K. R (Springer, 1989-03)
    The latitude zonal component of the large-scale solar magnetic field is analyzed using H-alpha charts for the 1905-1982 period, and the poleward migration of prominences is used to calculate the time of reversal of the ...
  • Nonpotential magnetic fields at sites of gamma-ray flares 
    Hagyard, M. J; Venkatakrishnan, P; Smith, J. B. Jr (American Astronomical Society, 1990-06)
    The relation between the degree of nonpotentiality of photospheric magnetic fields and the occurrence of gama-ray flares is examined to determine whether there are special signatures of the stressed fields for this type ...
  • Role of equatorial ionization anomaly in the initiation of equatorial spread F 
    Raghavarao, R; Nageswararao, M; Sastri, J. H; Vyas, G. D; Sriramarao, M (American Geophysical Union., 1988-06)
    A comparative study is made of the changes in the latitudinal structure of the F region electron density at fixed altitudes in the Indian equatorial region on days with and without postsunset onset of equatorial spread F, ...
