The Aachen Christmas market during the blue hour

Let's get together and take some pictures of the blue hour, lights, and people setting up for the Christmas market. (The market itself is only open from 18.00 till 21.00 on that first Sunday.) https://www.aachen-tourismus.de/erleben-entdecken/eventsundveranstaltungen/aachenerweihnachtsmarkt/
Sunset is at 4.40pm, so the blue hour will be directly after.
