Obiettivo With the present proposal we wish to revive an east-west collation in solar magnetography that was intensive and fruitful until the mid 1970s. The three NIS teams represent leading NIS institutes for ground-based solar physics, but their research programs have suffered from relative isolation and extreme decline in the fun- ding. Still they have developed highly original programs, and their research interests and capabilities are highly complementary to those of the INTAS participants. With a coordinated program we wish to make use of the promising, potential synergies.The most original observational NIS programs are presently the extensive measurements of the mean magnetic field of the Sun (SMMF) at Crimea and Irkutsk, the differential Doppler measurements for helioseismology at Crimea, and Stokes-V profile measurements with different spatial resolution at Irkutsk. We wish to support the modernization of the equipment used for these programs, and thereby assist with the extensive know-how in solar polarimetry and high- precision instrumentation that has been developed in Zurich and Potsdam.These observing programs of the global aspects of the Sun need to be connected to the various programs in the west (Zurich, Potsdam) for exploring the small-scale nature of solar magnetic fields (SMF). The flux tubes can be viewed as the basic building blocks for understanding of solar physics, including global parameters like SMMF and the solar irradiance. The connection goes via flux tube distribution functions, the large-scale flux topologies and patterns, their solar-cycle evolution, and ultimately the under- standing in terms of the solar dynamo.IZMIRAN has a long and successful record in the analysis of the large-scale evolution of SMF, their links to the solar corona and heliosphere, and their origin in dynamo processes in the Sun's interior. Zurich has used the synoptic magnetic-field data sets from Mt Wilson and Kitt Peak to explore the global evolution and rotational properties of the magnetic patterns, as well as their links to small-scale structures and processes. We wish to pool this know-how and coordinate the various approaches to arrive at a more comprehensive understanding of solar magnetism.Because of the potential for synergies and the many young scientists involved in the present project, the prospects for being successful in building a new base for future east-west collaboration in ground-based solar physics and solar magnetic field research must be considered as very good.
