Flare motion of h alpha kernels and coronal sources

Flare: motion of H-alpha kernels and coronal sources

Haisheng Ji

Purple Mountain Observatory

Nanjing, China


Method to determine the positions of

H-alpha kernel (centroid):

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

motion !


T1

T2

Region 1

Region 2


T1

T2

Region 1

Region 2





The November 1, 2004 M-class event taken at Purple

Mountain Observatory with 1s cadence



Rhessi HXR source

at different times


12-25 keV

‘Height’ of the

HXR sources

Centroid distance of the two

conjugate Ha kernels



  • Further work needed:

  • Classify H-alpha kernel motions

  • Get fine structure of H-alpha kernel motions

  • HXR source motions

To infer reconnection behavior

Thanks!
