NISP begun producing video summaries of solar activity as observed in H-alpha (upper row), magnetic field (low-left) and a broadband intensity (white light, low-right). A most prominent indication of solar activity is in the magnetic fields, which cover entire solar surface (red/blue correspond to positive/negative polarity). Dynamic nature of eruptions is clear from the H-alpha observations showing the chromospheric filaments (dark features in upper-left) and prominences (upper-right, bright features off solar limb). The sunspot activity (dark spots in low-right) is limited to areas of strong magnetic field. Video is a courtesy of Niles Oien (NISP/NSO).
