Left: space-time map obtained at disk center. Right: stokes images observed at disk center. These were observed in a spectral interval around the Sr I 4607 Å line, and averaged over ∼5.58 min (50 frames) from the beginning of the observation (see the temporal interval between horizontal red lines in the space-time map). The red vertical line in the Stokes I image shows the wavelength position used to generate the space-time map.
