| Abstract: |
Sunspots show oscillations of velocity, of intensity, and probably of the magnetic field; the oscillations are observed at different periods (2-3 min, 5 min, <= 20 min), at all height levels of the sunspot atmosphere, and with different spatial distributions and characteristic phase relations. In the present paper a short review on the various phenomena is given, with focusing on oscillations of the magnetic field at photospheric levels and on oscillations in the transition region to the corona above sunspots, derived from recent 2-D observations with high spatial resolution. The observed data are compared with the predictions from theory and modelling. |
