Spectropolarimetric time series data of sunspot NOAA 9448 were obtained in the Si I 10827 AA line and the He I 10830 AA multiplet with the Tenerife Infrared Polarimeter. Throughout the time series the spectrograph slit was fixed over a region covering umbra, penumbra, and quiet sun. We present properties of running penumbral waves in the chromosphere, their relation to both photospheric and chromospheric umbral waves, and their dependence on the magnetic field topology. |
