---------------------------------------------------------------- 20th Anniversary Symposium on Ionospheric Interactions in Tromso 10-11 October 2000, Ramfjordmoen, Norway ---------------------------------------------------------------- Dear colleague, Twenty years ago ionospheric HF heating experiments were begun outside of Tromso, Norway, on the EISCAT incoherent scatter radar site at Ramfjordmoen. To commemorate that event, we are organizing a small symposium on Tuesday and Wednesday, October 10 and 11, 2000. Background: The EISCAT HF facility, known as Heating, was originally constructed and operated by the Max-Planck-Institut fuer Aeronomie in Lindau, Germany, and is currently owned and operated by the EISCAT Scientific Association. EISCAT (European Incoherent SCATter) is an international association supported by the research councils of Finland, France, Germany, Japan, Norway, Sweden, and the United Kingdom. For further information please see http://www.eiscat.uit.no/heater.html and http://www.eiscat.uit.no/eiscat.html. Venue: The 20th Anniversary Symposium is expected to be held at the EISCAT Heating building, as was the inauguration 20 years ago. Program outline: Presentations are anticipated on * Past Heating achievements * Present status and outlook for the Heating facility * Status, capabilities, and results from other HF facilities * Report on the upgraded EISCAT radars * Future scientific directions in ionospheric interaction experiments * Future plans (e.g. SPEAR, magnetospheric radar, solar radar, etc.) On the evening of the 10th there will be a buffet/dinner at the Heating building. There will also be a demonstration of the "new" Heating control program and an opportunity to see the recently upgraded EISCAT radars. Participants: We anticipate a relatively small meeting, and space is limited. We ask those interested in attending to please please contact one of the persons listed below. We look forward to hearing from you, and to seeing you in Tromso.
