Abstract: The emergence of magnetic flux from the solar interior is commonly believed to be the physical process responsible for many dynamical phenomena observed on the Sun. In particular, the interaction between emerging magnetic flux and the pre-existing ambient fields causing magnetic reconnection has become a "hot" topic for both numerical simulations and high-resolution observations of the solar atmosphere. Small-scale brightenings, Ellerman bombs and surges, but also large-scale events, like flares and CMEs, have recently been interpreted as the response to the modification of the coronal magnetic field caused by episodes of flux emergence. I report on some case studies of high-resolution observations of flux emergence episodes at different spatial scales, carried out using both space satellites and ground-based telescopes, which have revealed clear signatures of the interaction occurring throughout the highly stratified layers of the solar atmosphere.
