    It was a wild week indeed. A huge shout-out to the Astro team at Wacken, but also at home helping us with the preparations and social media (in alphabetic order): Andreas Hänel, Carolin Liefke, Ekaterina Moerova, Florian Rünger, Gyula Józsa, Janine Fohlmeister, Jessica Koch, Lucas Krone, Marc Hempel, Nadya Ben Bekhti-Winkel, Patricia Aparicio Marcos, Robert Brose

    Thanks a lot to German Astronomical Society, @MPIfR_Bonn and #CRAF for supporting us financially.

    I just returned from an intense week in Grenoble, where we had our yearly Committee on Radio Astronomy Frequencies (#CRAF) meeting after a 2-day workshop of the IAU/CPS, which I co-organised. Our host, IRAM, was so kind to invite us to the NOEMA observatory on Plateau de Bure, a sub/-mm radio interferometer at 2550 m altitude. NOEMA just got a big extension and now features twelve 15-m antennas. I wanted to go there since many years and I'm super grateful to the IRAM that they made it possible.

    I'm not only a big fan of free open source software #FOSS, but also of open data. Compared to when I started with spectrum management (protecting radio astronomy frequencies) some ~10 years ago, the availability of public datasets with fantastic quality has sky rocketed.

    Today, we use Lidar-based topographic (height) maps, which help us determining the level of terrain shielding of our sensitive telescopes from terrestrial transmitters such as cell-phone towers. We can query openstreetmap to obtain road data - very useful if you want to study the impact of car radars on observations. Thanks to the European Copernicus programme, we also have access to population densities, land cover data and so much more.

    Thanks a lot also to the developers of easy-to-use software, which allows us to work with all these datasets with ease. We are truly standing on the shoulders of giants... The Committee on Radio Astronomy Frequencies (#CRAF craf.eu/) contributes a small part to this: with our #pycraf (pypi.org/project/pycraf/) software package for #Python, which can be used for spectrum management compatibility studies.

    Thus, #CRAF is hoping that regulation authorities will consider improving the situation. As this will take time, we are very happy that #SatCon operators so far are very cooperative. 6/

    #CRAF also made a press statement about the new finding today. esf.org/news-media/news-press-

    CRAF is an expert committee of the European Science Foundation. 4/

    Some of us are also heavily involved in spectrum management. That is we go to meetings of the ITU-R and other organisations to fight for an interference-free environment at the radio telescopes.

    Our spectrum management work is mostly done under the umbrella of the Committee on Radioastronomy Frequencies (#CRAF, craf.eu/). CRAF was involved with the compatibility calculations done in ECC Report 271 (docdb.cept.org/document/1032).
