    Purpose

    SHINE promotes research on the processes by which energy in the form of magnetic fields and accelerated particles is produced by the Sun, and on the mechanisms by which this energy is transported through the inner heliosphere. The focus is on the connection between events and phenomena on the Sun and related solar wind structures and other in situ measurements in the inner heliosphere.

    SHINE has recently decided to encourage detailed studies of a few carefully selected events that may help advance this research. 'Campaign' refers to a concerted, focused effort on one or more event periods or topics, usually taking place over a limited time period with the goal of a final report or papers devoted to the results of the campaign. Since coronal mass ejections (CMEs) are the primary transient phenomena that cause the largest interplanetary disturbances, driving shock waves that in turn accelerate particles and cause the largest geomagnetic storms, it was decided that the SHINE Campaigns should focus on a few carefully selected CME Events. Thus, the overarching theme of the SHINE Campaign Events program is to improve our understanding of both the CME process and the coronal and solar wind context in which they occur. Three general questions that the Campaigns address are 1) How are CMEs initiated? and 2) How do CMEs evolve or propagate? and 3) How are CME-related solar energetic particles accelerated and transported? Bringing as much data and interpretation to bear on a given event as possible, the Campaigns will address these questions by confronting current and developing CME models with observational data and simulations, thereby forcing comparisons between existing models and guiding the development and improvement of new models and simulations. This approach should help us to both enhance our physical understanding of the eruption and propagation of CMEs and to improve our predictive capabilities.


    Method

    Because of the large, continuous data sets and modeling techniques that have become available since the start of the SOHO era, it was decided to select events occurring since 1996. The chosen events should have reasonably complete data on both its solar source regions and its propagation through the low corona into the heliosphere. It is desirable but not essential to include Earth-directed events so that their in-situ and geoeffective characteristics can be studied. Four events or event periods were selected before the SHINE 2003 Workshop, and 3 leaders assigned to guide the work on each event. Dave Webb and Nick Arge are co-leaders of the overall Campaign Events program.

    Why were these particular events selected? The May 1997 event has already been well studied and the pre-event and event solar and heliospheric background conditions were relatively simple, therefore good for modeling. This event has been and is being studied in the SHINE-GEM-CEDAR Campaign, MURI and CISM. The May 1998 event is also a MURI event and has good vector magnetic field data (on AR 8210) with which to work. Both of these events drove shocks and caused major storms at Earth. The focus on these two events will be on CME initiation and transport and why they were geoeffective.

    The two 2002 events focus on a specific problem in current SEP research, the origin of variability at high energies. Because the events were far west, the high-energy particle production reflects conditions near the Sun. But SEPs above a few tens of MeV/nuc in these two events have dramatically different spectral and elemental composition characteristics, even though the associated CMEs and flares were ostensibly rather similar. Because these events occurred on the west limb, there were no ejecta observed at Earth. But the active regions that spawned these events (9906 and 10069, respectively) also produced many other flares and the CMEs in the ~10 days preceding these events. It is hoped that comparative studies of the earlier history of these events may also shed light on what made the west-limb events so different.

    These events were also selected to address key science topics or themes, each of which was discussed by an invited speaker at SHINE 2004. Three themes were selected and their questions and speakers are:

    1) Solar Theme: "What are the roles of the magnetic field, dynamics and evolution in CME initiation?"; George Fisher.

    2) Interplanetary Theme: "How can heliospheric observations be used to better understand the transport and evolution of the solar magnetic field as it affects CMEs and SEPs?"; Ian Richardson.

    3) SEP Theme: "Can we identify solar/IP factors that drive SEP spectral and compositional variability at high energies?"; Allan Tylka with short presentations by Nariki Nitta, David Alexander, Matt West, Mike Andrews, and Mike Reiner.

    The Event Leaders have agreed to encourage and facilitate communications among researchers working on these particular events. A preliminary website has been established for aiding researchers in these studies, in particular for depositing pertinent data and for exchange of models and simulations and general discussions involving these events and the science themes. The current URL is: http://cdaw.gsfc.nasa.gov/SHINE_Campain/. If you wish to become involved with one or more of these events and science themes, please contact the appropriate Event Leader. Each leader will maintain an up-to-date email address list for email communication with the members of his Event study group.

    The Community Coordinated Modeling Center (CCMC) has simulated the SHINE events using the MAS model. The MAS model is a MHD Model of Solar Corona developed by J. Linker, Z. Mikic, R. Lionello and P. Riley. The results of these runs can be accessed at the CCMC web page http://ccmc.gsfc.nasa.gov by clicking the SHINE Campaign Events link on the side bar menu. Also, additional runs can be requested by using the Runs on Request link.
