It is actually the transition between corona and the photosphere. Out of the three layers of the Sun’s atmosphere, chromosphere is the second one (with photosphere being the first layer and corona as the third).

In the standard flare model (Carmichael1964;Sturrock 1966;Hirayama1974;Kopp & Pneuman1976), the fundamental mechanism of solar flares is believed to be magnetic reconnec-tion in the corona, converting the magnetic energy into kinetic and thermal energy.
