Flows in and around Active Region NOAA12118 Observed with the GREGOR Solar Telescope and SDO/HMI

Popis výsledku v původním jazyce

Accurate measurements of magnetic and velocity fields in and around solar active regions are key to unlocking the mysteries of the formation and the decay of sunspots. High spatial resolution images and spectral sequences with a high cadence obtained with the GREGOR solar telescope give us an opportunity to scrutinize 3-D flow fields with local correlation tracking and imaging spectroscopy. We present GREGOR early science data acquired in 2014 July August with the GREGOR Fabry-Perot Interferometer and the Blue Imaging Channel. Time-series of blue continuum (lambda 450.6 nm) images of the small active region NOAA 12118 were restored with the speckle masking technique to derive horizontal proper motions and to track the evolution of morphological changes. In addition, high-resolution observations are discussed in the context of synoptic data from the Solar Dynamics Observatory.
