We present the semi-empirical model of a powerful solar flare on July 19, 2000 based on spectral observations in the Fe I, Fe II, Cr I, and Ti II lines. Our calculations show the existence of a very narrow (≤ 100 km) and sharp magnetic field peak at photospheric level (log τ5 ≈ −2). It is possible t...
