7519 Flares
Scientific paper
We study high resolution observations of a compact impulsive C9.0 flare. We include in the analysis high cadence Hα -1.3~Å filtergrams from the Big Bear Solar Observatory (BBSO), radio data from Owens Valley Solar Array (OVSA), soft and hard X-ray data from Yohkoh, and UV~1600~Å continuum images from Transition Region And Corona Explorer (TRACE). Observations show two emission kernels located at the feet of a general bipolar structure. The impulsive phase of the flare consisted of two major emission peaks in hard X-ray, radio and Hα emission, each lasting for about a minute, indicating the existence of two major episodes of flare energy release. We find that these different episodes in the flare temporal evolution were related to different spatial locations as shown by the Hα kernels. The high cadence time profiles at various wavelengths exhibit temporal structures on a shorter time scales from a few seconds to less than a second, while Hα - 1.3~Å and radio images show that the location of the footpoint emission was shifting. This may be an indication that emission in these two episodes was produced in different magnetic structures, which we explore through spectral analysis of hard X-ray and microwave emission.
