Description
Summary:High-resolution observations of the solar photosphere have revealed the existence of structures composed oftiny Magnetic Bright Points, or MBPs. Such small-scale structures are associated with regions of strongmagnetic field on the order of kilogauss (kG). Various studies have investigated some of the physicalproperties of MBPs thanks to high-resolution observations that currently allow defining details and evolutionof these structures. The present study analyzes some of these dynamic parameters through the use oftime series of images of the solar photosphere acquired with the HiFI/GREGOR high-resolution groundbasedsolar telescope in the G band (4308 Å) and the space-borne telescope Hinode. MBPs are tracked todetermine their proper motions. Additionally, light curves are obtained that show its variation in intensityand the behavior of size and trajectory throughout its life time is analyzed. The results establish that themeasurements of the dynamic parameters of the MBPs are influenced by the instrument used, since differentparameters are obtained with the change in spatial and temporal resolution.
