Direct measurement of intensity and photographic subtractions of simultaneous Doppler filtergrams at Hc~zk0.3 ,~ in a time-lapse sequence of McMath 11482 has shown velocity oscillations in sunspot umbrae. These oscillations exhibit the following characteristics: (a) A characteristic oscillation freq

Our theory of a resonator for slow magneto-atmospheric waves in the chromosphere of a sunspot umbra has been used to check different models of the structure of the chromosphere and transition region. Oscillations of velocity and intensity in CIV, SiIv, and OIv lines observed by Gurman et al. (1982)
