Abstract * : All of the solar dynamics are triggered and created by the various types and manifestations of the solar magnetism. Among the manifestations are solar pores which can be seen as small-scale sunspots missing the penumbra and hence featuring only a strong vertical magnetic field creating a dark spot in photo-heliograms. In the current contribution, we would like to present the morphologic evolution of a very dynamic pore in the strongly evolving active region NOAA 12682. Morphologic changes, i.e., the shape of the pore, can tell us not only about the configuration of the magnetic field, e.g., if the pore is structured by multiple cores, as in our case but also about MHD waves, which are of importance for the heating of the upper solar atmosphere. In this first contribution about our ongoing study we would like to discuss in more detail about the variation of the intensity, size, and morphologic appearance of the pore during a high resolution, high-cadence observation run recorded by the HiFi instrument of the European large-aperture solar telescope GREGOR.
