Evolution of the flare in Hα. Three magnetic field contours (±50, ±100, and ±500 G) of the closest in time MDI map were added to panel c) in a continuous magenta (cyan) line for positive (negative) field. The three brightest kernels were labeled as K1, K2, and K3 in panel d). All images have a FOV of 290 per 200′′, similar to that of Figs. 2 and 4. The white dashed line in panel e) indicates the direction along which the height-time measurements in Fig. 7 are performed.
