In the January 16, 2019 Sixty Symbols video Where is the edge of space? Dr Meghan Gray from the University of Nottingham discusses Jonathan McDowell's paper The edge of space: Revisiting the Karman Line and says:

There’s been enough recent attention to the idea that the Karman line needs to be redefined, that the organizations that deal with aeronautical things and the organizations that deal with astronautical things are proposing to get together in the coming year to have a symposium to look at the scientific and the political and whatever arguments go into this to see if we need to actually have a definition of where is space and what that (line) might be.

Question: Has this symposium been named and scheduled? Has it taken place? What are the aeronautical and astronautical organizations that are sponsoring it?

Please: limit debate about the underlying physics or definitions. This question is about the symposium event.

    $\begingroup$ Did Jonathan tell you why not? Does the FAI want to remain in ignorance? $\endgroup$
