The 19th NSO/Sac Peak Summer Workshop, scheduled for the week of 28 September-2 October 1998, will concentrate on the physics through high spatial and temporal resolution observations of the solar atmosphere. Recent observations from the ground and space have produced solar images of spectacular resolution. Advances in ground-based observations, such as frame selection and image reconstruction, as well as recent space-based observations (in particular those from SoHO), dramatically enhance our understanding of magnetic concentrations, weak fields, flux tube physics, coronal interactions, magnetic canopies, and photospheric flows and dynamics. Nevertheless, theoretical models and numerical simulations show that key physical processes occur on scales below those currently resolved. New observational techniques, further developments in image processing and data analysis, as well as advances in both ground- and space-based instrumentation, will be essential to understand the magneto-hydrodynamics of the solar convective zone and atmosphere.
This workshop will review recent progress in the areas of theoretical modeling and observations of magneto-convective physics on scales below 1000 km. There will be discussions on techniques for achieving high-resolution observations, large-aperture solar telescopes, and proposed high-resolution space missions such as Solar-B and Solar Lite. The scientific focus will be on questions such as: How do small-scale features observed in the photosphere drive physical processes in the upper atmosphere? What is the relation of weak fields to the solar cycle? Can we observe surface dynamo magnetic field generation on granular scales? What are the smallest observable magnetic elements?
The meeting will consist of several invited reviews, selected oral contributions and poster summaries, and poster papers. There will be ample time for poster reviewing and discussions. Oral presentations will be held in the new Sunspot Astronomy Education Center. Posters will be displayed nearby in the Sunspot Community Center. The presentations made at this meeting are intended for publication.
Abstract and registration information should be submitted by 15 May 1998. A second announcement will be issued in the near future. The total number of participants will have to be limited to the capacity of the meeting facilities (approximately 80). There will be a registration fee of $80. Limited funds are available to help defray travel and housing costs for participants in need.
