Discussion 1 : What exactly do we mean by "merging" and "reconnection" in observations? ### Questions raised by audience ---> answered by ### V. Vasyliunas and I. Axford chair: R. Lundin Discussion 2 (with beer): Alternatives for plasma entry into the magnetosphere: micro-process mechanisms, locations, and extends. ### view by high-altitude / theory people ### R. Thorne, B. Sonnerup chair: R. Lysak Discussion 3: convection and velocity filter Distinguishing between temporal and spatial structures How "physically" meaningful is a convection velocity? - when there are parallel electric fields. - when plasma is non-Maxwellian with multiple convection velocities. - May we "map" it along the field lines? P. Reiff, D. Knipp, V. Vasyliunas, J. Clemmons chair: M. Yamauchi Discussion 4: mapping To what degree can we map or identify "open/closed" regions (separatrix)? Relation between aurora, radar signature, and particle population Statistics vs. Case studies L. Lyons, D. Winningham, A. Yahnin, K. Stasiewicz chair: R. Smith Discussion 5: restriction Where does the frozen-in approximation break down? What is the appropriate Ohm's law in that region? Validity of fluid approximation / "convection velocity." Deformation of the "signatures" when travelling along the field lines. May we ignore the effect of the solid earth? What physics/quantity do we miss in 2-D assumptions? B. Lysak, D. LeQueau, L. Block chair: L. Lyons Discussion 6: Q & A session Questions raised by audience, and answered by panel members. Which "boundary process" can/cannot be detected at low-altitudes? How can we detect and distinguish them at low-altitudes? TBD members : R. Smith, C.-I. Meng, R. Greenwald, C. Carlson, B. Clauer chair: D. Sibeck Discussion 7: New Tools and Future Method T.
