This imagery from the Swedish 1-meter Solar Telescope (SST) at La Palma, Spain is part of a series of multi-wavelength observations of a solar active region. The goal of the observations was to better understand the methods by which non-thermal energy is injected into the solar chromosphere by mechanisms such as emerging magnetic fields in sunspots (Click Here)
