Analysis methods of the flow field around decaying sunspots

Hanna Strecker, Nazaret Bello González

The moat flow, a radial outflow surrounding fully fledged sunspots, is a well characterised phenomenon. Nevertheless, its origin and especially its relation to the penumbra is stil…

Evolution of the flow field in decaying active regions, Transition from a moat flow to a supergranular flow

Hanna Strecker, Nazaret Bello González

We investigate the evolution of the horizontal flow field around sunspots during their decay by analysing its extension and horizontal velocity around eight spots using SDO/HMI Dop…

Photospheric Magnetic Fields of the Trailing Sunspots in Active Region NOAA 12396

M. Verma, H. Balthasar, C. Denker +27

The solar magnetic field is responsible for all aspects of solar activity. Sunspots are the main manifestation of the ensuing solar activity. Combining high-resolution and synoptic…

Chromospheric impact of an exploding solar granule

Catherine E. Fischer, Nazaret Bello González, Reza Rezaei

Observations of multi-wavelength and therefore height-dependent information following events throughout the solar atmosphere and unambiguously assigning a relation between these ra…

High-resolution imaging spectroscopy of two micro-pores and an arch filament system in a small emerging-flux region

S. J. González Manrique, N. Bello González, C. Denker

Aims. The purpose of this investigation is to characterize the temporal evolution of an emerging flux region, the associated photospheric and chromospheric flow fields, and the pro…

Flows in and around active region NOAA12118 observed with the GREGOR solar telescope and SDO/HMI

M. Verma, C. Denker, H. Balthasar +28

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…
