The obs. picture shown at the right side is from 2005. 

A afternoon in 2005 with very special weather conditions when the sun disappeared below the horizon. The observatory at that time was not finalized and among other things the rotating roof was not yet made and mounted.

Hi Niels,
This is a reminder that your Public folder links will become inactive on March 15. On that date, your Public folder will become a standard Dropbox folder, and your files will remain safe in your account. If you want to share those files again, you’ll need to use shared links instead.

The Public folder was the first sharing method we introduced, and since then, we’ve built more sophisticated ways for you to share securely and work together with your team. In addition to shared links, we have a number of sharing options designed to make collaboration easier and give you more control.

We understand these sharing methods are not a direct replacement for the Public folder in some cases—we apologize for the inconvenience this may cause. For more information on transitioning from the Public folder to shared links, visit our Help Center.

UPDATE of links is on-going!
