We expect to see new bright regions close to the footpoints or moving bright features. He and OV lines would be useful to align all the observations. One large full disc magnetic map each 96 mn will be sufficient. The target and precise schedule will be given daily. The coronal loops are good diagnostics to derive the magnetic field lines and to study the interaction of emerging and pre-existing magnetic fields.
Magnetic extrapolation allows to understand where the energy can be released.
We would derive the hydrogen column density of the cold plasma related to the destabilization of filaments. As we expect flares, soft X-ray images of the AR, are required as frequently as possible.
