Kodaikanal Hα monochromatic and white-light observations are used to study the circular flare of 14 March, 1984. We report here the dynamic activity of the Hα filament, which attained a severe twist before erupting as a 4B flare. We feel that the r

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 Hα filaments are a proxy for the neutral lines. The chan

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

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 Hα filament positions to evaluate the shear in the neutral line. We find
