Sonder-VA 20
I'm not able to find reliable information about an event called "Sonder-VA 20" — the name doesn't match a widely documented event I have knowledge of. It could possibly refer to a "Sonderveranstaltung" (German for "special event") numbered 20, such as a session at a university, trade fair, or convention, but I can't confirm details without more context.
