-------------------------------------------------------------------- 1. TENTATIVE LIST OF SPA SPECIAL SESSIONS AT 1995 SPRING AGU MEETING -------------------------------------------------------------------- From: Bob Lysak (bob@aurora.spa.umn.edu) To the SPA community: Following is the tentative list of special sessions proposed by the SPA section for the spring meeting this year, which will appear in the 2nd call for papers, scheduled to be published in the January 3 issue of EOS. Please note that while this list is rather full, there is still a chance to suggest additional special sessions. Please contact the relevant secretary (SA: Odile de la Beaujardiere, odelabe@nsf.gov; SH: Ed Roelof, roelof@aplsp.dnet.nasa.gov; SM: Bob Lysak, bob@aurora.spa.umn.edu) if you have a suggestion for a special session for the spring meeting, or even for the fall meeting. Please note that the deadline for abstracts for the AGU Spring meeting is March 9. Odile, Ed, and Bob SA01 Models and observations of light ions in the plasmasphere (Joint with SM) The purpose of this session is to: (1) present and review existing models of the plasmasphere (2) review morphology as revealed by existing measurements from ground and space-based instruments (3) present latest observational developments (e.g., incoherent scatter radar, EUV imaging, ground-based optical measurements) (4) help determine future directions and opportunities.

Both NASA and NSF have developed programs to encourage the development of high technology tools to provide public access to the Internet in addition to a revitalized commitment to bringing innovative teaching methods to the classroom. There is an explosion of information available on the Internet relevant to all aspects of Space Sciences. This session will highlight the public outreach efforts undertaken by individuals and groups. The session will include an oral session and a poster/demonstration session, where we plan to provide full Internet access. Contributions are solicited on innovative outreach efforts such as: precollege and college programs which include curriculum development efforts utilizing recently acquired remote sensing data, high technology, and the Internet; collaborative efforts between scientists and representatives from the formal or informal educational community, including teachers, curriculum development specialists, librarians, and museum specialists; and information resources available over the Internet that focus on getting research results to the general public. Individuals or groups which maintain World Wide Web pages which present Space Physics and Aeronomy related results are encouraged to provide the convenors with their URL, so that their outreach efforts can be highlighted at the session and on the individual section's home page.

SA03 TOPICS IN AERONOMY AND IONOSPHERIC PHYSICS: The Influences of William B. Hanson (Joint with SM) This session is intended to accumulate contributions from scientists influenced by the work of W.B. Hanson and to acknowledge his contributions in a wide variety of fields. We would like to receive contributions in aeronomy and ionospheric sciences related to atmosphere and ionospheres energy budget, ionospheric plasma structures and thermal plasma dynamics. Contributions in other areas representing the breadth of Hanson's interests are also welcome. * Convener: R.A.

Considerable progress has also been made in high resolution measurements of the Sun's surface and atmosphere from ground-based observatories and from space-based instrumentation such as Yohkoh. Within the next few years, we anticipate observations with even higher resolution and accuracy from SOHO, TRACE, and SOLAR-B, while simulations based upon realistic and comprehensive models will be developed, with both observations and theory leading toward new forecasting capabilities. Hence, it is now timely to compare diagnostics available from simulations and measurements. Papers are solicited for this session that will engage both solar observers and plasma theorists in the exchange of latest results and thereby lay the groundwork for future integration of measurements and simulations.

The session will highlight (but will not be restricted to) first results from the NSF SunRISE program as well as recent observation and modeling efforts from the international SOLar Electromagnetic Radiation Study for Solar Cycle 22 (SOLERS22). SunRISE addresses the question of solar influences on global change (particularly climate and ozone changes), using a program of ground- based observations to augment recent space measurements of total and spectral solar irradiance changes. Also included are Sun-as-a-star studies, paleoclimatic indicators, and theoretical analyses. SOLERS22 involves observation and modeling of variations in visible, ultraviolet, extreme ultraviolet, X-ray, and total solar irradiance over long-term (years) or intermediate-term (4-10 months) during Cycle 22 and predicted for Cycle 23.

Since the pass is taking place during the approach to solar minimum activity, one might expect that the variations in plasma, fields and energetic particles at Ulysses will be dominated by latitudinal structures (e.g., crossing the streamer belt). However, even the earliest measurements as Ulysses transited 80.2 deg south indicated a "hysteresis" effect in which some data could not be ordered solely in heliolatitude. The Ulysses pole-to-equator measurements could also be affected by variations with helioradius, temporal variations, a magnetic field not symmetrical about the rotation axis, or some other unexpected phenomena. This all-contributed session solicits papers on the latest Ulysses observations and correlated measurements from other spacecraft or ground-based solar observatories, as well as theoretical analysis and modeling of this previously unexplored region of the inner heliosphere.

Papers are solicited for this session that will bring together the wide range of new observations and theoretical developments that are now filling in our understanding of how these particles originate, get accelerated, and manifest themselves throughout the heliosphere over the course of the solar cycle.

On the sun, helical fields exhibit global distributions that may have their origin in the solar dynamo. There has been a growing awareness that twisted magnetic fields not only play a central role in producing solar activity, but that they can be detected in the solar atmosphere and their properties measured (e.g., Yohkoh X-ray images of sinuous structures erupting in the solar corona). Such fields injected into the heliosphere have been identified with interplanetary magnetic clouds and flux ropes. Spectra of magnetic helicity have been measured in the solar wind and related to the propagation of cosmic rays. Magnetic helicity conservation has been invoked to explain various magnetospheric phenomena. Papers are solicited for this session from solar, space, and laboratory researchers, both observational and theoretical, concerning the topology, consequences, applications, and limitations of the dynamics of magnetic helicity in plasmas.

Evidence gathered over the past several decades indicates that solar flares may have only a marginal relationship to many of the interplanetary effects once attributed to them. This has led Gosling (JGR, 98, 18937, 1993) and others to declare that the traditional paradigm -- large solar flares are a fundamental cause of solar-terrestrial events -- is a myth, and that the central causal role should be given to coronal mass ejections (CMEs). Many of the transient disturbances which affect the near-Earth space environment can indeed be associated with CMEs, but the question of how CMEs are related to solar surface flare brightenings remains controversial. Papers are solicited for this session that will air the various points of evidence for or against "the solar flare myth".

This session will feature reports from the experimenter teams on first observations and solicits papers from the community on "first results" from WIND as well as from related observations from other spacecraft and/or ground-based observatories .

To be useful in operational forecasting, the algorithms must present their results in easily understandable visual displays. This session will give developers of space weather algorithms and displays an opportunity to show how far the field has advanced. The lecture session will have both invited and contributed presentations and similarly for the demonstration/poster session. An oral presentations can be combined with a demonstration in the demonstration session. There will be an attempt to coordinate the session by asking presentors to illustrate their products with events chosen from a small number of well documented space weather events. Conveners: R.L.
