H-alpha flare of 14 March, 1984 -- Evidence for reconnection?

Sundararaman, K; Aleem, S. M; Singh, J; Selvendran, R; Thiagarajan, R (Springer, 1994-01)

Kodaikanal H-alpha monochromatic and white-light observations are used to study the circular flare of 14 March, 1984. We report here the dynamic activity of the H-alpha filament, which attained a severe twist before erupting ...
Magnetic shear in flaring regions. I - Quantitative evaluation of the change in shear

Sivaraman, K. R; Rausaria, R. R; Aleem, S. M (Springer Netherlands, 1992-04)

We have evaluated the shear angle of the neutral line of the non-potential magnetic field for one or two days prior to and after the flare event for 10 cases. We have used the Hagr filament positions to evaluate the shear ...
On the triggering of a spotless double-ribbon flare

Rausaria, R. R; Aleem, S. M; Sundararaman, K (Springer Netherlands, 1992-11)

We have studied the evolution of the double-ribbon, spotless flare of 21 February, 1992, using Kodaikanal Hagr and Kf1 observations. The analysis of the data shows that the Hagr filament underwent a large change in shear ...
