  • Improving the image quality at the calcium K and hydrozen spectroheliographs at the Kodaikanal Observatory 
    Singh, J; Aleem, P. S. M; Nagabhushana, B. S (Indian Institute of Astrophysics, 1988-01)
  • Magnetic Activity and the Enhanced 5303 Ã Emission in Solar Active Regions 
    Ramesh, K. B; Nagabhushana, B. S; Varghese, B. A (Springer, 2001-03)
    Analysis of the intensity maps of Fexiv emission at λ=5303 Å obtained from the observations of ground-based coronagraphs during the sunspot minimum period 1985 and 1986 shows the persistent presence of localized strong ...
  • One dimensional prominence model 
    Nagabhushana, B. S (The European Southern Observatory, 1998-05)
    Based on reasonable assumptions and mathematical approximations a one dimensional, analytical model for solar quiescent prominences is constructed, which is in both magneto-hydrostatic and thermal equilibrium. Thermal ...
  • Photospheric field gradient in the neighbourhood of quiescent prominences 
    Nagabhushana, B. S; Gokhale, M. H (Springer, 1990)
    We have determined statistically the horizontal gradiant of the vertical magnetic field in the neighbourhood of filaments inside and outside the active regions during a few months in 1981 and in 1984. The results show that ...
  • A Speckle Experiment during the Partial Eclipse 
    Saha, S. K; Nagabhushana, B. S; Ananth, A. V; Venkatakrishnan, P (Indian Institute of Astrophysics, Bangalore, 1997)
    An experiment for the speckle reconstruction of solar features was developed for observing the partial eclipse of the sun as viewed from Bangalore on October 24, 1995. No data could be obtained because of cloudy sky but ...
  • Study of calcium-K network evolution from Antarctica 
    Singh, J; Nagabhushana, B. S; Babu, G. S. D; Uddin, Wahab (Springer, 1994-08)
    To study the evolution of large convective cells known as supergranules, a solar telescope was set up at Maitri, Indian permanent station in Antarctica region, during the local summer months (December 1989 through March ...
  • Transient activity in the loop prominence system of a flare active region 
    Bagare, S. P; Nagabhushana, B. S; Aleem, P. S. M (Astronomical Society of Indian, 1989-09)
    Solar limb observations of the activity in a loop prominence system associated with an active region were obtained on February 2, 1984. The activity was observed for a total duration of over seven hours of which the maximum ...
