Flare motion of h alpha kernels and coronal sources

Method to determine the positions of

H-alpha kernel (centroid):

But, we need to subtract the background, in order to get the real

motion !

Rhessi HXR source

at different times


Flare motion of h alpha kernels and coronal sources

12-25 keV

‘Height’ of the

HXR sources

Centroid distance of the two

conjugate Ha kernels


Flare motion of h alpha kernels and coronal sources

The M-1 class flare of July 26, 2002


Flare motion of h alpha kernels and coronal sources

  • Further work needed:

  • Classify H-alpha kernel motions

  • Get fine structure of H-alpha kernel motions

  • HXR source motions

To infer reconnection behavior
