NGC 5982 is known to be one of those elliptical galaxies that have peculiar kinematics in their centres. In this paper, optical spectroscopic observations are presented, which show that a specific feature is present in the velocity field of NGC 5982. This suggests that the kinematical behaviour is the result of projection effects in a dynamically

We present a consistent model of storage, instability and dynamical eruption of magnetic flux tubes in the solar convection zone and underlying overshoot region. Using a convection zone model with self-consistent overshoot layer, we calculate equilibrium configurations of magnetic flux tubes and determine their linear stability properties, taking

The aims, achievements and plans of the Working Group on `Radioastronomical Databases' of IAU Commission 40 are outlined. Special recommendations emerged from its present first meeting. These regard the electronic availability of published tabular data, the educational needs to prepare for the age of `Network Astronomy', the preparation of a master
