✦ Synopsis

Observations of the MglI h line in the umbrae of five sunspots show a spread of a factor of 3 in peak intensity. This range is larger than, and brackets, the range found in a single umbra by Lites and Skumanich (1982).

The magnetoacoustic modes excited in a thermally conducting polytropic fluid layer in the presence of a vertical magnetic field are examined with a view to classify them with the help of phase diagrams. The possibility of identifying the umbral flashes with overstable magnetoacoustic modes is explor

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)
