We present the results derived from the analysis of the first spectropolarimetric (SP) data obtained through the Interferometric BIdimensional Spectrometer (IBIS) at the Dunn Solar Telescope (NSO). The analysis is focused on 10³ G small scale (∼100 km) magnetic field concentrations observed, in a quiet Sun region, as bright points in G-band filtergrams. The combination of high spatial and temporal resolution of both SP and G-band datasets allowed us to analyze in detail the magnetic properties of bright points over different spatial scales (from ∼eq. 0.4″ up to 2″– 3″) and temporal scales (from 10 min up to > 60 min) and, beside this, to focus on the dependence of significant physical quantities (i.e., magnetic field strength and filling factor derived from Stokes profile inversion) in relation with such evolutions.

We present two main results of our analysis: i) evolution of bright points over small spatial scales and short time intervals (by considering the coalescence of small and faint bright points into a single high brightness one); ii) magnetic properties of bright points over large spatial scales (by examining a small network patch). Our study indicates an interesting correlation between G-band brightness and magnetic filling factor fluctuations. On the contrary, we have not observed any correlation between G-band brightness and magnetic field strength. Such a result can help us to conclude on the possible fine structuring of kG concentrations in the solar photosphere which produce brightness enhancement in G-band filtergrams.
