High resolution observations of chromospheric network
Abstract
There is an increasing evidence that primary driver of solar variability, on time scales of days up to the solar activity cycle length, is the evolution of magnetic field present on the solar surface. In this paper we investigate the correlation between the photospheric structures and emerging magnetic elements by means of high spectral resolution images containing network cells. We present the preliminary results derived from the analysis of observations carried out in the spectral lines Ca II 854.3 nm, Fe I 709.0 nm and Fe II 722.4 nm with the 2-D Interferometric Bidimensional Spectrometer IBIS installed at the DST - Dunn Solar Telescope, Sacramento Peak (NM).
