Scientific paper

Simultaneous observations have been made of velocities in the chromosphere (in H-alpha) and in the photosphere (in the nonmagnetic Fe I line at 5526-A) of three sunspots. The results reveal waves propagating horizontally outward across the penumbra in the photosphere with about the same period as the running penumbral waves in H-alpha (250-290 s). The photospheric waves are more intermittent and have higher horizontal phase velocity (by a factor of 2 or more) than the chromospheric penumbral waves.
