30th anniversary of the Museum Industriekultur – kosmos-os was there

The Museum of Industrial Culture Osnabrück (MIK) had asked whether we at kosmos-os would take part in the planned birthday party on Sunday, September 1st, 2024. After all, there is a proven good cooperation with our Sternstunden on the Vosslinke. We were happy to comply with the request.


At 10:30 a.m. we "rolled in" with our astronomical equipment. We found that the MIK had prepared very well. From the market stand that had already been set up and marked with our name, to the friendly approach of the organizers on site, the parking solution, the supply of electricity and even coffee and food for us exhibitors, everything had been thought of. The best thing: the sun was shining from a cloudless blue sky - a picture-perfect summer day!


Our stand was divided into two parts: where the sun shone freely from the sky, we had set up our telescopes - solar observation is a fascinating thing. Our information stand was placed where the warehouse building cast a large shadow. We had the first interested visitors while we were setting it up. After all, there was a lot to see.


We had set up four telescopes, two for visually observing the sun and its sunspots in white light and one for digitally recording the sun on a tablet. With a telescope specially prepared for observation in so-called H-alpha light, you could even observe flares and prominences of the sun.


The information stand was primarily intended to make astronomy more understandable. There were several globes on display showing our earth, the moon and the starry sky. A mechanically moving model of our solar system (a so-called orrery) exerted a strong attraction and we were able to explain a lot about the movements in our solar system. To illustrate the proportions, there was also a sun model with a diameter of 60 cm and an earth of the same size (just the size of a pearl), which was placed about 60 m away.


The stream of visitors to our site didn't stop all day. There were many amazed looks and many interested questions that we answered. Our visitors were not only adults, but also many children - mostly with their parents - who often had an astonishing knowledge of astronomical relationships. At 6 p.m. in the evening, when the last visitors said goodbye, we at kosmos-os were able to look back on a challenging but all-round successful day at the MIK - also due to the summer temperatures.


Impressions


Setting up the telescopes in the morning. Note the position of the sun.
Everything is ready. The visitors can come.
The sun rewarded our efforts. There were many sunspots and prominences to observe.
Fascinating flareloops on the Sun's surface (H-alpha light)
Our telescopes in the front. A miners choir in the background.
It was a real summer festival. We at kosmos-os were right in the middle of it.
It's better to close one eye.
In the shade it was easy to have discussions.
In the afternoon we had to move the telescopes to the magazine building because the sun had moved.
Just before the end, a quick look at the sun. Note the position of the sun.
