Evolution of the small-scale loop emergence event in the internetwork observed with SO/PHI. The plotted FOV has dimensions of 18 × 16 Mm². We show in each row the SO/PHI LOS magnetogram (to the left) and the total linear polarisation (to the right). In the last row we show, additionally, the same region in the EUV at the last two timesteps. The green box delimits the two emerging opposite polarity features in the SO/PHI magnetograms and the strong total linear polarisation (TLP) patch in between the emerging magnetic features in the TLP maps. The yellow arrow in the EUV images in the last row points to the campfire event, which has a dot-like shape. The maximum brightness according to the campfire detection algorithm is reached at 17:16:36 UT. The dashed black box at 17:06:45 marks the images at the time of maximum linear polarisation signal and vertical magnetic flux within the green box.
