Abstract:
In this paper we present the analysis of a dynamic 3B/X2 solar flare from superactive region NOAA 9236 and its
associated phenomena. The Hα observations of this flare have been carried out with Solar Tower Telescope at
Aryabhatta Research Institute of Observational Sciences (ARIES), Nainital, India. The flare was also observed by
various space- and ground-based instruments like SOHO, TRACE, HXRS, Nobeyama Radio Observatory, etc. The
flare shows impulsive nature in different wavelengths, along-with long duration events (LDE) like phenomena
viz. associated with type II radio bursts, strong halo coronal mass ejection (CME), proton flare, which are
generally associated with LDE. We examined the energetics of CME associated with this flare using
SOHO/LASCO data. We found that the potential and kinetic energy increases at the expense of magnetic
energy, as the CME moves. This demonstrates that the flux ropes are magnetically driven.
