EXCURSION:

Depends on the final budget of the workshop. Usually it is a place of scientific excellence, and by rule is not very distant (connected to the first sentence it is one or a half day trip).  The images are from the one of most productive comet photometry,  world site, The once private Crni vrh Observatory. The excursion take place in the 1998..

A excursion in the real "underground's" it is very probable in the nearby "Podbaredine cave". The alternative can be the visit of the _remnants_ of the 19. century world famous "K und K Krigsmarine Pola Sternwarte", the Austro-Ungarian Naval Observatory  in the city of  Pula (ironed during the W.W.II by US bombers). From that observatory Johan Palisa started his exceptional, all 19record breaking, work on asteroid.
