Arbeitskreis Meteore e.V.
Have you ever seen a shooting star? Sure you have. And you will also have noticed colourful rings around the sun, which appear from time to time. People who witnessed auroras or noctilucent clouds will surely be less. All these phenomena have in common that they are somehow connected to the atmosphere of the earth. People who are interested in those phenomena have joined in the "Arbeitskreis Meteore e.V." (AKM). In the present mode, our association has been existing since 1990, but it originates from a group of observers who joined in 1975
