Coronal emissions in Fe IX, the chromospheric network in Ly-α, and the photospheric LOS magnetic field. Left panel: coronal structures seen in 171 Å by SDO/AIA, showing a complex loop system. It is divided by loops, which are either northward or southward directed. The southward loops seem to consist of medium-sized coronal structures, which are directed purely southwards, and longer ones, which are pointing towards the south-east. Central panel: upflow region located on a bright structure of the chromospheric network, measured by HRI_Lya. Right panel: photospheric magnetic field revealing a strong positive polarity beneath the coronal upflow. It reaches values above 100 G. A black box in the south-west of the structure shows a region where we measure flux cancellation.
