The MIST (Magnetosphere, Ionosphere, Solar Terrestrial) spring meeting will provide a forum for the presentation and discussion of recent advances in all areas of MIST science. The MIST community is interested in physical processes within the Sun-Earth system and other planets. This includes studies of the mesosphere, ionosphere, thermosphere and magnetosphere of the Earth and of other planets and the solar wind.

Taking advantage of the MIST meeting's integration with the European Week of Astronomy and Space Science there will be a number of sessions exploring common themes between MIST science and Astronomy and Solar Physics. These themes include particle acceleration and transport, magnetic reconnection, MHD seismology, and the unusual solar minimum of 2007-2008. In addition there will be a Missions Forum looking at current and future missions in the fields of Solar Physics and Solar Terrestrial Physics.

MIST Sessions

MHD seismology of solar, space and astrophysical plasmas

Organisers: I. De Moortel (St. Andrews, UK), M. Mathioudakis (QUB, UK), V. Nakariakov (Warwick, UK), M. Volwerk (Graz, Austria)

Magnetic Reconnection

This is a joint session between MIST and UKSP and is open to any papers discussing magnetic reconnection - theoretical or observational - in space, solar and astrophysical plasmas.

Particle acceleration and transport in the heliosphere and beyond

Energetic particles are universally observed at the variety of astronomical scales: from extragalactic jets through supernova explosions down to Earth's ionosphere. The myriad of spacecrafts orbiting the Earth and traveling in the interplanetary space provide us with unprecedented quality observations of the Sun, heliosphere and various astrophysical objects in a broad range of energies with the angular resolution never available before: from gamma rays, through Xrays, UV/optical, radio and can detect particles directly in interplanetary space. Although the spatial and temporal scales are different, the questions how energetic particles acceleration are evenly vital for various astrophysical communities.

Organisers: E. Kontar (Glasgow, UK) V. Zharkova (Bradford, UK) and D. Burgess (Queen Mary, UK) S. Chapman (Warwick, UK)

The unusual(?) solar minimum of 2007-2008

Ongoing observations of both solar and heliospheric phenomena are revealing that the current solar minimum at the end of solar cycle 23 is remarkably different from any other during the past 40 years. This period corresponds approximately to the era of modern space and ground-based observational techniques and it is more difficult to tell whether similar minima are common on longer timescales of solar activity. The present polar photospheric magnetic field strength is almost half of the typical value from recent cycles, polar coronal holes are less well formed and show evidence of a lower temperature, the strength of the heliospheric magnetic field at 1 AU is about a third lower than previous minima, and the dynamic pressure of the solar wind is of the order of 20% lower than the previous cycle at all latitudes, the weakest it has been during the era of in-situ spacecraft measurements. This session will aim to attract observational studies of both the solar and heliospheric aspects of this unusual minimum and papers attempting to interpret and explain what is happening. Can we tell if this solar minimum is indicative of a longer term change in solar activity or simply an outlier on the broad spectrum of solar activity variations?

Organisers: R. Forsyth (Imperial, UK), S. Matthews (MSSL, UK)

Heliospheric and astrospheric structure and planetary interactions

The aim of the session is to bring together the communities studying solar wind structure and solar wind/planetary interaction in the solar system and those working on astrosphere/exoplanet coupling. Results from new heliospheric missions (particularly STEREO) and improvements in ground-based observations are providing an entirely new view of the development of heliospheric structure, while Venus Express and Messenger are yielding detailed information on solar wind/planetary coupling in the inner regions of the heliosphere. The physical processes controlling the development of heliospheric structure solar wind-planetary interaction, as well as many of the phenomena observed in the solar system will also be found in the development of structure in astrospheres and their the interaction of those structures with exoplanets. The aim of this session is to bring together the communities studying solar wind structure and planetary interaction and the exoplanets community, using the new results for the solar system to help understand stellar wind/planetary coupling in other systems. At the same time, the diversity of exoplanetary systems will encourage new ways of thinking about how these processes operate in different environments and how this casts light on heliospheric/planetary interaction in the solar system. All researchers who are interested in the Sun-heliosphere-planetary connection are invited to participate and to contribute to this session, and we would especially like to invite those working on astrosphere/exoplanetary analogues of heliospheric/planetary coupling.

Organisers: A. Breen (Aberystwyth, UK), M. Bisi (University of California, USA), H. Lammer (Austrian Academy of Sciences, Austria)
