| description | 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. |

Las observaciones en alta resolución de la fotosfera solar han revelado la existencia de estructuras compuestasde diminutos Puntos Magnéticos Brillantes o MBPs (por sus siglas en inglés). Tales estructuras a pequeñaescala están asociadas con regiones de campo magnético fuerte del orden de kilogauss (kG). Diversasinvestigaciones han estudiado algunas de las propiedades físicas de los MBPs gracias a observaciones de altaresolución que permiten en la actualidad definir detalles y evolución de tales estructuras. El presente estudiohace un análisis de algunos de estos parámetros dinámicos a través del uso de series de tiempo de imágenesde la fotosfera solar adquiridas con el telescopio solar terrestre de alta resolución, HiFI/GREGOR en labanda G (4308 Å) y el telescopio espacial Hinode. Se realiza el seguimiento de los MBPs para determinar susmovimientos propios. Adicionalmente se obtienen curvas de luz que evidencian su variación en intensidad yse analiza cómo es el comportamiento del tamaño y de la trayectoria a lo largo de su tiempo de vida. Losresultados establecen que las medidas de los parámetros dinámicos de los MBPs están influenciadas porel instrumento utilizado, ya que con el cambio de la resolución espacial y temporal se obtienen resultadosdiferentes.
