Abstract:
I propose to introduce issues concerning shapes and brightness of 107 K
thermal flare loops. In particular the observations that show that
during the early stages of flares loops containing the 107 K thermal
plasma appear to be taller than wider where the loop section with the
smallest radius or curvature appears to be located at the vicinity of
the loop top. As flares evolve loop footpoints separation appear to
increase at a larger rate than their height resulting in an
ever-decreasing height to width ratio. As the loop evolves and become
flatter the section with the smallest radius of curvature that
originally was confined to the loop top also evolves and spreads.
Observations indicate that during the early stages of flare lifetimes
the brightest parts of loops are confined to those sections having the
smallest radius of curvatures.
