In the 70's the Dutch public observatory Simon Stevin got their hands on a 7.5mm Würzburg radar.
This radar was dismantled and moved to the observatory, where it was cleaned, reconstructed and from there on used to observe the sun for radio bursts.
Together with their optical solar observatory, they did work on comparing radio bursts with optical flares.
For two years now I have volunteered at the modern reincarnation of the Simon Stevin observatory, now called Tivoli.
The Tivoli observatory has many objects, including the main Simon Stevin dome and 12" Maksutov telescope.
Also among the collection of items they inherited are many hundreds of 35mm slides. It has been my job to digitize these unique photographic records in high-quality and publish them.
