The central European climate in Germany is not ideal for serious astronomical observations. Increasing light pollution hampers thousands of amateur astronomers and millions of people from seeing starry skies and the Milky Way.To study the sources of light pollution, we estimate the increase of light pollution in Osnabrück, a town of about 160,000 inhabitants located in northwestern Germany. We try to extrapolate these statistical data to Germany and discuss possible reasons for increasing light pollution though the energy consumption stagnates. Some enthusiasts of the German amateur association “Vereinigung der Sternfreunde” have formed a working group DARK SKY to exchange information on this matter. Finally, we present some activities to make the public aware of the problem.

After 3-year discussions within a working group of the Japanese CIE and then 2-year discussion under a committee of the Environmental Agency in Japan, “Guideline for Light Pollution - Aiming for Good Lighting Environments” was published by the Environmental Agency. This is the first governmental guideline in the world and therefore a good example to be discussed in the other countries.

In this paper, astronomy activities in Turkey in the year of 2019 are summarized. Especially, public outreach activities and teacher training programs in the framework of IAU 100 celebrations are given. Current status of the Eastern Anatolia Observatory and Turkish Space Agency are also summarized. Finally, recently established working group on the legislation for the light pollution is introduced.

Earth Dynamics

An ideal definition of a reference coordinate system should meet the following general requirements:1. It should be as conceptually simple as possible, so its philosophy is well understood by the users.2. It should imply as few physical assumptions as possible. Wherever they are necessary, such assumptions should be of a very general character and, in particular, they should not be dependent upon astronomical and geophysical detailed theories.3. It should suggest a materialization that is dynamically stable and is accessible to observations with the required accuracy.

Observational Techniques

The focus of discussion in Working Group 3 was on the Thermodynamic Properties as determined spectroscopically, including the observational techniques and the theoretical modeling of physical processes responsible for the emission spectrum. Recent advances in observational techniques and theoretical concepts make this discussion particularly timely. It is wise to remember that the determination of thermodynamic parameters is not an end in itself and that these are interesting chiefly for what they can tell us about the energetics and mass transport in prominences.
