Long Duration Events in Magnetic Arcades and Large Loops
Abstract
A number of long duration flares, with decay time between 1 and 17 hours, have been analysed using the Yohkoh Soft X-ray Telescope images and spectra from the Bragg Crystal Spectrometer. X-ray images suggest that these events typically occur in the following magnetic field configurations: magnetic arcade, expanding arch, or large loops triggered and heated up by a low-lying, compact, impulsive flare located below these high loops. A continued energy release is observed during decay of these events. Single loop flare models should not be indiscriminately applied to analysis of thermodynamics of these flares due to their more complex structure and restructuring of the magnetic field, and often increasing height.
