In 2006, the Astronomical Observatory of the University of Coimbra (Coimbra, Portugal) – Observatório Astronómico da Universidade de Coimbra (OAUC) - will celebrate the 80th anniversary of performing the first spectroheliographic observations in Coimbra. Full-disk spectroheliograms have been routinely taken in the Ca II K-line (K1 and K3) and in 1990 regular observations in the Hα line have also started (sample spectroheliograms can be downloaded here).
This anniversary is an excellent opportunity to organise an international solar physics meeting, jointly with a historical session commemorating the life and work of Prof. Francisco Costa Lobo (1864-1945) who installed the spectroheliograph in Coimbra in the 1920s. The instrument itself is a twin of the spectroheliograph operated at the Observatoire de Meudon. The Coimbra University itself (founded in 1290) is one of the oldest European universities. The meeting will take place on its campus just inside the Coimbra historical down-town and will also include an excursion to the Coimbra Observatory which is located at the city periphery.
The scientific meeting will cover various aspects of chromospheric plasmas which are particularly well observed in the above-mentioned Hα and Ca II lines, but also in a variety of other lines including the UV and EUV spectral range. This will include the structure and dynamics of the chromosphere (cell interior, network, spicules etc.) as well as other features seen at the chromospheric level or having the properties of plasmas at chromospheric temperatures: sunspots chromosphere, plages, chromospheric flares, prominences and filaments etc. The relation of such plasmas to other atmospheric layers and/or processes will also be discussed, in particular using the UV and EUV data from SOHO (ESA/NASA) and other space telescopes.
A long-term (cyclic) evolution of the chromosphere and its activity, including solar irradiation variations and effects on space weather, will be included, in particular with respect to long-term observations made in Coimbra. Finally, since this meeting is organised around the above-mentioned anniversary, a session devoted to new solar instruments capable of observing chromospheric plasmas will be held (including the space instrumentation).

Several social events are planned during the Meeting. On Tuesday there will be a visit to the Old Library "Biblioteca Joanina" of the University of Coimbra. On Wednesday afternoon, we plan an excursion to the Astronomical Observatory in Coimbra and the Archeological site of Conimbriga (the ruins of a Roman town, beautiful mosaics: more information on this page http://www.conimbriga.pt/index_en.html). These visits are included in the registration fee. On Thursday evening, we are organizing the Conference Dinner in the "Palácio S. Marcos", an old Portuguese edifice located 20 km from Coimbra.
