Overview maps of the observation No. 3 (left panel) and No. 4 (right panel). Bottom row, left to right: continuum intensity at 1083 nm, 854 nm, 630 nm, and 396 nm. Top row, left to right: unsigned wavelength-integrated Stokes V signal around Si i at 1082.7 nm, line-core intensity of the Ca ii IR line at 854.2 nm, unsigned wavelength-integrated Stokes V signal around 630 nm, and line-core intensity of Ca ii H at 396.85 nm. The red contours outline strong polarisation signals. The white squares denote co-spatial local darkenings.
