Description

Soft X-ray images of the 1B/M4 flare of 7 April 1980 (start at 00:50 UT) recorded by Flat Crystal Spectrometer aboard Solar Maximum Mission satellite were analyzed. The X-ray flare consisted of two patches about 1 arcmin apart. Comparisons with magnetograms and white light images indicate that the two soft X-ray patches originate from two different loops or systems of loops. Systematic displacements of the brightest points of the patches are clearly seen during the flare development. For two selected resolution elements of the X-ray pictures (one element in each patch), a detailed differential emission measure analysis has been carried out and time evolution of the mean electron density and thermal energy content has been investigated.
