Activities

Presentation of the AVV at the 'Dorf- und Gästefest' in Schalkenmehren on July 10, .2022. Frank Bonn, Uli Klein, Robert Oster, Harald Simon, Arend Sommer and Jochen Wüstenhagen were present to answer any questions of the many visitors. Quite a few telescopes were set up, and occasionally the sun appeared so that sunspots could e sshoewn to the visitors in white light, and prominences in Hα.. A talk entitled Faszinierendes über Schalkenmehren was given in the DGH.

Clearing-out action on March 20, 2021. Parts of the meridian instrument find a new home in the main building of Bruno Nelles. Really heavy stuff - bulging muscles needed! The 'Gang of Four': R. Oster, R. Goffart, J. Wüstenhagen, G. Herzogenrath.

Surprise on May 7, 2021: In search for the main water tap, our experts discover a 'dungeon' beneath a floor plate (that had never been taken notice of), which is more than 4 m high and subtends the enture diamter of the 6-m dome. Apart from the main tap, three control boxes and a car windscreen are found (but no skeleton). Our 'archeologists': J. Wüstenhagen, R. Goffart und R. Oster.

Renovation on May 19, 2021 - with a lot of drive and in good mood. Our 'artists': R. Oster, J. Wüstenhagen, R. Goffart, H. Simon.

Renovation with 'full staff' on June 26, 2021.

The partial solar eclipse on June 10, 2ß21 has been documented photographically by some members with their private equipment. AVV could not offer any public viewing of the eclipse, owing to the pandemic. Here is a small collection of imges of the eclipse:

Uli Klein has refurbished his 50 years old refractor for the eclipse. He had devised the projection screen at the time in such a way that I could superimpose a coordinate grid for any orientation of the sun, onto which he drew the sunspots with a sharp pencil. Still today, the projection works pretty well as can be seen here.
