Atmospheric temperature and AIA 1600 Å and Hα brightness in the emerging loop. a) Photospheric temperature map at log τ₅₀₀ = −1 from the Fe i 6301–6302 Å inversion. b) Chromospheric temperature map at log τ₅₀₀ = −3 from the Ca ii 8542 Å inversion. c) AIA 1600 Å intensity on a logarithmic brightness scale. d) Hα line-core intensity. The irregular contours enclose locations with T> 8 kK in the log τ₅₀₀ = −3 map. The dotted and dashed horizontal lines are the cuts shown in Fig. 10. The green dotted line is the path shown in Fig. 13.
