1997 Volga Space Plasma Physics Summer School Information: The purpose of these Summer Schools, held every second summer onboard a river cruise ship on the Volga and organised jointly by the Radiophysical Research Institute (NIRFI), Nizhniy Novgorod, Russia and the Uppsala Division of the Swedish Institute of Space Physics (IRFU), Uppsala, Sweden, is to give an introduction to modern space plasma physics by bringing together experienced researchers, young scientists and scholars in astrophysics, space physics and plasma physics for a fruitful exchange of ideas across areas of interest, language, culture and age barriers.
The topics covered include linear and non-linear plasma physics, waves and radiation phenomena in plasma, waves in random media and turbulence, planetary, solar and stellar coronal plasma, plasma under extreme conditions in space, space plasma radio emission, radio methods for investigating space plasma environments, and the use of the Earth's ionosphere and magnetosphere as a space plasma laboratory for model experiments simulating phenomena in other plasma environments.

Phase-diverse speckle reconstruction of solar data ( PDS ): Award-winning paper: " Phase-diverse speckle reconstruction of solar data," by John H. Seldin and Richard G. Paxman, Environmental Research Institute of Michigan. --ABSTRACT-- Phase-diverse speckle imaging is a novel imaging modality that makes use of both speckle-imaging and phase-diversity concepts. A phase-diverse speckle data set consists of one conventional image and at least one additional image with known phase diversity for each of multiple atmospheric phase realizations. We demonstrate the use of a phase-diverse speckle data set collected at the Swedish Vacuum Solar Telescope on La Palma to overcome the effects of atmospheric turbulence and to restore a fine-resolution image of solar granulation. We present preliminary results of simultaneously reconstructing an object and a sequence of atmospheric phase aberrations from these data using a maximum-likelihood parameter-estimation framework. The consistency of the reconstructions is demonstrated using subsets of the sequence of images pairs.
