The method of has been used with a variety of spectral lines to study oscillating longitudinal gas velocities inside solar magnetic elements. Oscillations have been found inside all elements observed, the amplitudes increasing with height from typically +0.27kms -I in Fe 15166 ~ (a line of low orig

The line-centre magnetogram technique has been used to study velocities at spatial scales ~>5" in several umbras without interference from light scattered from the surrounding non-magnetic photosphere. In addition, more traditional velocity observations of one sunspot were also analysed. The velocit

Radiative damping of waves is important in the upper photosphere. It is thus of interest to examine the effect of radiative relaxation on the propagation of waves in an intense magnetic flux tube embedded in a uniform atmosphere. Assuming Newton's law of cooling, it is shown that the radiative energ

Greenwich data for proper motions of the components of sunspot groups are analysed. We have found that only 4}'0 of the 408 examined sunspot groups do not show systematic proper motions of the components at the beginning of their life. Interpreting proper motions as the results of ascending subphoto
