                WG1: RECONNECTION ELECTRIC FIELD AND MAGNETOPAUSE 
			  BOUNDARY NORMAL MAGNETIC FIELD
              Co-chairs:  Larry Lyons and Odile de la Beaujardiere

Primary goals:  Evaluate dayside reconnection electric field and normal
                component of magnetic field at the magnetopause. 

Approach:  Evaluate ionospheric plasma transport in the vicinity of the
           open-closed field line boundary and dayside boundary layers and the
           large-scale transport over the polar caps. 

Dec. 6 discussion was divided into three topics as follows:

I.  Coordination between modeling and data campaigns
    A.  Considerable time was spent discussing where the magnetic separatrix
        maps to in the ionosphere.
            a.  Generally it is assumed to be near boundary between low-
                latitude boundary layer (LLBL) and cusp/mantle, since LLBL is
                believed to be on closed field lines. 
            b.  New model results by Lyons and Schulz suggest LLBL is on open
     		field lines and that separatrix is at equatorward boundary of
     		LLBL (which would make separatrix identification in ionosphere
                easier than we had believed, since it would not be necessary to
                distinguish the cusp from the LLBL). 
     	    c.  It was agreed that we should pursue this topic with our
                campaign data 
     B.  A proposal for using models to predict polar cap regions and
         convection patterns for comparison with campaign observations was 
         presented by Lyons and discussed.
     C   Results and implications of boundary particle mappings from the
         magnetosheath to the ionosphere were presented by Onsager . 

II.  Presentations of campaign data (not included in AGU talks)
     A.  AMIE potential patterns for the entire Jan. 27-29, 1992 period were 
         described by Gang Lu.
     		1. Results available on microfiche
     		2. We decided to lump together data from periods of relatively 
     		   stable IMF for comparison with models and determination of
                   boundaries and boundary regions from satellite particle data.
     B.  Odile discussed ionospheric T and n data from Sondrestrom for Jan. 27,
     	 1992, and inferred LLBL precipitation features. 

III.  Future campaigns identified (i.e., 15-28 March, 1993; 9-10 Nov. 1993;
     		11-14 Jan., 1994)
