| Zusammenfassung |
In this paper we present new results of spectra-photometrical
investigations of the flaring kernels' sizes and their intensities
measured simultaneously in various parts of the Hα line
profile. Our investigations were based on the very high temporal
resolution spectral-imaging observations of the solar flares
collected with Large Coronagraph (LC), Multi-channel
Subtractive Double Pass Spectrograph and Solar Eclipse Coronal
Imaging System (MSDP-SECIS) at Białkow Observatory
(University of Wrocław, Poland).
We have found that the areas of the investigated individual
flaring kernels vary in time and in wavelengths, as well as the
intensities and areas of the Hα flaring kernels decreased
systematically when observed in consecutive wavelengths toward the
wings of the Hα line. Our result could be explained as an
effect of the cone-shaped lower parts of the magnetic loops
channeling high energy particle beams exciting chromospheric
plasma. |
