  • Effects of magnetic shear, spot, and plage rotation on prominence evolution 
    Rausaria, R. R; Gupta, S. S; Selvendran, R; Raman, K. S; Singh, J (Kluwer Academic Publishers, 1993-08)
    We have studied the evolution of two dark H-alpha filaments as prominences during their disk passage from February 12 to February 19, 1992 and from March 6 to March 17, 1992, using Kodaikanal Observatory H-alpha and Ca II ...
  • The variation of filament direction in a flaring region 
    Rausaria, R. R; Raman, K. S; Aleem, P. S. M; Singh, J (Kluwer Academic Publishers, 1993-07)
    We have analyzed the variations in shear angle over a time interval of 30 s during a flare on June 11, 1991, using Kodaikanal Observatory spectroheliogram and photoheliogram data, and assuming H-alpha filaments are a proxy ...
