DYNAMICAL PROPERTIES OF THE CHROMOSPHERE IN AND OUT OF THE SOLAR MAGNETIC NETWORK

We present the results of a comparative analysis of an 83 minute time sequence of spectra taken around the Ca II K and He I 1083 lines, near the center of the solar disk and away from active regions. We discuss the behavior of the Fourier spectra at low frequency: 3 minute oscill ations are well observed out of the network, and 5 minute oscillations waves are prominent in the network. The 5 s sampling time also permit s the observation of the high-frequency part of the Fourier spectra of intensity and velocity fluctuations at different heights. At high fre quencies, K2V-K2R and 1083 (velocity) results differ when magnetic and non-magnetic regions are compared.
