摘要

Spectropolarimetric time series data of the primary spot of active region NOAA 9448 were obtained in the Si 110827 A line and the He 110830 A multiplet with the Tenerife Infrared Polarimeter. Throughout the time series the spectrograph slit was fixed over a region covering umbra, a light bridge, penumbra, and quiet sun. We present speeds of running penumbral waves in the chromosphere, their relation to both photospheric and chromospheric umbral oscillations, and their dependence on the magnetic field topology.
