Analysis of photospheric magnetic fields in AR 12546: a case study

Abdelkawy, Ali G. A.; Shaltout, Abdelrazek M. K.

We investigate high-resolution observations with the spectropolarimeter (SP) aboard the Hinode satellite of the Solar Optical Telescope (SOT) of a positive polarity sunspot of an active region (AR) (NOAA 12546). We present a case study for the properties of the thermal, magnetic field, and plasma flows as a function of the optical depth from the i…
