Overview of impacts 14 and 15, as seen in UV (1600 Å) and EUV (171 Å) channels. The red/blue contours outline magnetic fields of +/−50 G. a) Composite of 1600 Å and downflow tracks. b) 171 Å base-difference image showing a faint downflow. c), d) 171 Å base-difference images of the impact, scaled between ± 300 DN s^-1. The white arrow points to the position of a very faint falling fragment. It is visible in the movie. Impact 14 is the compact site indicated by an arrow in c). Impact 15 is the large region of diffuse 171 in d).
