文摘

The dynamic regime of eight regions in the quiet solar chromosphere was analyzed. Observations in CaII lines were performed with a moderate spatial resolution of around 2- The purpose of this study was to compare the diagnostic capabilities of these observations with high-precision measurements conducted in recent years by different authors with new-generation instruments. Being probably of importance in the chromospheric heating, the recently revealed structural formations (magnetoacoustic portals, magnetic aureoles, and magnetic shadows) were found to manifest themselves at moderate resolutions too. These findings are important in the context of investigations of coronal hole bases conducted by the authors with the same observational data.
