Fine-scan velocity and magnetic-field measurements in solar active regions

Solar Physics, 1971
Fine scan (5″ × 5″ aperture) simultaneous Doppler and magnetograms have been obtained over solar active regions near the central meridian passage. Besides the mainly horizontal Evershed motion in sunspots, there appears a conspicuous descending motion over all active regions.
