3. FIRST ANNOUNCEMENT AND CALL FOR PAPERS FOR IAGA SYMPOSIUM 8

IAGA DIVISION IV SYMPOSIUM 8: Local Interstellar Cloud and the 
			      Boundary of The Heliosphere
                       
  
The physical properties of the circumsolar interstellar medium are 
the boundary conditions for the solar wind expansion and determine 
its confinement and the size of the heliosphere. Informations on 
this medium can be deduced from properties of species having entered
the heliosphere, i.e. Anomalous Cosmic Rays and interstellar Pick-up
ions abundances, interstellar neutrals distributions and 
differential behavior induced by coupling with the plasma at the 
interface. On a larger spatial scale, constraints on the Local Cloud
surrounding the Sun and its companion clouds are given by nearby 
stars spectroscopy, while information on the general physical state
of the Local Bubble (the interstellar "cavity" containing the Local
Cloud) as its total pressure, magnetic field and cosmic rays content,
etc.., comes from a large set of astronomical observations. The aim 
of this session is the confrontation of all these observations with
those directly related to the size of the heliosphere, as the 2-3 kHz
radiation and cosmic rays distributions, in a search for a coherent
picture.
