Violau (Augsburg) – Germany, 6 – 9 September 1990

  • 9th meeting
  • Local organizers: Detlef Koschny, Hans-Georg Schmidt, Dieter Heinlein.
  • 58 participants from 13 countries: Australia (1), Belgium (7), Bulgaria (1), Croatia (2), Czech Republic (2), Germany (32), France (2), Hungary (3), Russia (1), the Netherlands (2), Slovenia (1), Spain (3) and the U.K. (1).
  • 19 presentations (17 lectures, 2 posters) of which 17 were included in the Proceedings.
  • IMC 1990 Proceedings (ISBN none): 64 pages (eds. Detlef Koschny, Dieter Heinlein).
  • Contents: Physics of meteoroids – zenith attraction – Tunguska Expedition 1990 – telescopic Aquarids – radiants in Per/Aur – fireball sounds – Glanerbrug meteorite – electrostatic meteor observing.
  • Participation fee 70 Euro.

This was so far the only IMC that took place at the same location as a previous meeting, the Bruder-Klaus-Heim in Violau (see 1985). The location also contains the public observatory of Martin Mayer. From the workshops, participants will never forget the demonstrations of practical daily life in East Siberia by Korlevic Korado who had taken part in a Tugunska expedition. The friendly atmosphere, typical for the IMC tradition, dominated this IMC. For a last time, the role of IMO in the IMCs was questioned by participants opposed to such formal organizational structures. At the closing ceremony of the 1990 Conference, the organizers, as well as IMO officials, stressed that meteor observers are like one family, and that non-IMO members will be always as welcome as IMO members at future IMCs.
