Left panel: broad-band MOMFBD reconstructed image from GFPI at 09:58 UT. Right panels: temporal evolution of the Doppler velocity (b) and temperature (c) at log τ = −0.6 inferred from the inversion of the Fe i 6173 Å line (GFPI data), and the intensity evolution in G-band (d) and Ca ii  H(e) from HiFI at the position indicated by a red line in panel a. Time is indicated in minutes after 09:00 UT. The vertical dashed line denoted as t_f marks the time of the beginning of the flare and the dashed line t_b indicates the arrival of the plasma blob to the light bridge. The blue arrow in panel a points to the location of the spectra illustrated in Figs. 7 and 8.
