Hence, processes occurring at the magnetopause and the nearby boundary layer, including the exterior cusp and various high- and low-latitude boundary layers, have received increasing attention in recent years. Observations and simulations indicate that these boundary layers exhibit rather complicated structures, with numerous types of transient events super-imposed upon them. The majority of these regions and transient events must map down to a relatively small area in the vicinity of the mid- and low-altitude cusp. Hence mid- and low-altitude investigations provide an opportunity to obtain a global view of dayside magnetospheric processes. In fact, ongoing and future projects sponsored by the GEM, ISTP and other programs are dedicated to just such studies. Because we can expect a wealth of observations concerning the cusp and related magnetospheric phenomena within the next few years, this is a good time for a large part of the space science community to get together to discuss the diverse observations of dayside polar phenomena and assess plans for future research. We do not aim to impose a unified interpretation, but rather try to gather different views and learn from each other. Science always allows different ways of explanation of the same physical phenomena (e.g., the wave and particle views of atoms). This is especially true in space physics, where the observations generally don't suffice to nail down a unique possible interpretation. We would consider this conference a success from a purely scientific point of view if it enabled us all to understand the contending physical explanations. This is why we have named the conference after Hannes Alfv'en who tried to bring up controversial ideas all the time. Panel discussions will help us to open up our minds to novel ideas. As the title indicates, we focus more on the low-altitude observations: -- what do they really indicate? -- what is the relation to the high-altitude phenomena (this is why we need updated information of high-altitude observations)? -- what should we invest in the future (both low- and high-altitudes)? -- etc. -------------------------- Dates: September 9-13, 1996 It is the week after the URSI meeting in France, but unfortunately on the same week as ICPP meeting in Japan. Mid-September is definitely one of the best period of Kiruna with nice colours in the field and in the night sky. Location: Kiruna, Sweden Abstract Deadline: Sometime spring 1996 (T.B.D.) Preliminary Main Program (we focus on observations but do not exclude theory): * Ground observations (optics, radar, magnetometer, etc.) * Satellite observations (Wind, Polar, Cluster, Interball) * Sounding rocket observations * Conjugate satellite and ground observations * Distinguishing between temporal and spatial structures * Limits and advantages of each observational tool * Use and Abuse of solar wind data set * Mapping and boundary conditions for modelling * What do the data and theories really imply? * Limits and advantages of assumptions in observations and theories. Discussion Hours (we will reserve ample time for this): * Panel discussion + open debate * Examples of the possible themes: "where does the frozen-in approximation break done / what is the appropriate Ohm's law in that region?" "where are the magnetosheath plasma access regions?" "how solidly can we define 'open' and 'closed' regions / to what extent, and how, can the separatrix be identified?" "data analyses with vs. without guiding models" Convenors: Rickard Lundin (IRF-Kiruna, Sweden) Larry Lyons (Aerospace Corp., USA) Dave Sibeck (APL/JHU, USA) Confirmed program committee members include, Tohru Araki (Kyoto U., Japan) Rob Elphinstone (U.

How many different source processes are there? Active optical phenomena in sub-auroral region. Poleward moving auroral forms (optic/radar/particle). Poster review Afternoon ^^^^^^^^^ 8. (continued) discussion 6 Abuse of data / instrumental effect / mistakes in case and statistical studies or (view by low-altitude people) Where are the magnetosheath plasma access regions? Is such plasma access an intrinsically time dependent or time independent process? Evening ^^^^^^^ Q & A session (= discussion 7) In this session, theorists + high-altitude observationalists outline their predictions for low-altitude phenomena, e.g., "can we detect...?" "Is it really the signature of...?" for both transient and steady state, and low-altitude observationalists describe the features they have seen. We attempt some reconciliation. How can we detect and distinguish them at low-altitudes? Which "boundary process" can/cannot be detected at low-altitudes? Day 5 (Friday) 8:30-12:00 ^^^^^^^^^^^^^^^^^^^^^^^^^ Morning ^^^^^^^ 9.

(2) Friday night (960913, 2000 UT = 2200 LT) There was a "typical" substorm breakup at the center of the sky. The local magnetic disturbance was 600 nT. The pulsating aurora was seen about an hour later. * There is a special session in next EGS (Vienna, 21-25 April, 1997). Abstract deadline is 15 December, 1996. ST10 High-latitude magnetosphere: New results from recent projects (e.g., Interball, Polar, Fast, SuperDarn, and Svalbard Radar) Although the first attempt of CLUSTER failed, there are many new high-latitude magnetospheric/ionospheric projects which successfully deliver data in 1996. This symposium will provide an opportunity of deep scientific discussions by gathering "hot results" of the new high-latitude missions. Papers from the Interball, Polar, and Fast satellites, SuperDarn related radars, and the EISCAT Svalbard radar are especially encouraged. Convenors (1) M.
