Hard X-ray Emission During Flares and Photospheric Field Changes
O. Burtseva, J. C. Martínez-Oliveros, G. J. D. Petrie +1
We study the correlation between abrupt permanent changes of magnetic field during X-class flares observed by the GONG and HMI instruments, and the hard X-ray (HXR) emission observ…
