Large Photospheric Doppler Shift in Solar Active Region 12673. I. Field-aligned Flows

Large Photospheric Doppler Shift in Solar Active Region 12673. I. Field-aligned Flows

Delta ( δ ) sunspots sometimes host fast photospheric flows along the central magnetic polarity inversion line (PIL). Here we study the strong Doppler shift signature in the central penumbral light bridge of solar active region NOAA 12673. Observations from the Helioseismic and Magnetic Imager (HMI)...
