In the standard magnetic reconnection model of
Carmichael-Sturrock-Hirayama-Kopp-Pneuman-Tsuneta,
the coronal X-point is expected to rise during a flare.
This increase in the cusp altitude implies a magnetic
footpoint connectivity with progressing footpoint separation. Using the forward-fitting method, the source
centroids of footpoints can be traced with super-resolution.
We plan to test the CSHKPT model statistically in a number
of RHESSI observed flares.
