Nandi Indian Institute of Science Education and Research Kolkata Abstract. The Sun's magnetic cycle governs its radiation levels, particle flux output and the frequency of solar magnetic storms. Collectively these phenomena create space weather which impacts space- and ground-based technologies and drives Earths atmospheric dynamics. This has created the need to develop numerical model-based forecasting of solar activity. Successfully addressing this goal necessitates an understanding of the physics that governs high Reynolds number turbulent plasmas in the Suns interior, and building predictive dynamo models based on this understanding. This has remained an outstanding challenge for the community. In this talk, I will discuss the advances we have made in understanding the physics of solar cycle predictability over the last decade and present a physical model-based forecast for sunspot Cycle 25.

Solar activity is powered by free energy stored in magnetic fields and driven by evolving conditions. The strongest magnetic fields and highest amounts of free magnetic energy are present in solar active regions. Throughout their evolution, from their emergence through their decay, active regions are centres of magnetic activity, with the level and type of activity phenomena being dependent on the evolutionary stage of the active region. I will make an overview of typical dynamic events, which characterise specific evolutionary stages of active regions and also review how the magnetic evolution of active regions is reflected in the evolu- tion of plasma parameters, coronal plasma composition and flows, which are also magnetically driven.

Linan1, E. Pariat1, K. Moraitis1, G. Valori2, J. Leake3 1LESIA, Observatoire de Paris, Universit´ePSL, CNRS, Sorbonne Universit´e,Univ. Paris Diderot, Sorbonne Paris Cit´e,Meudon, France 2Mullard Space Science Laboratory, University College London, Holmbury St. Mary, Dorking, UK 3NASA Goddard Space Flight Center, USA Abstract. Relative magnetic helicity is a gauge invariant quantity suitable for the study of the magnetic helicity content of heliospheric plasmas. Relative magnetic helicity can be decomposed uniquely into two gauge invariant quantities, the magnetic helicity of the non- potential component of the field, and a complementary volume-threading helicity. Recent analysis of numerical experiments simulating the generation of solar eruptions have shown that the ratio of the non-potential helicity to the total relative helicity is a clear marker of the eruptivity of the magnetic system, and that the high value of that quantity could be a sufficient condition for the onset of the instability generating the eruptions. This study introduces the first analytical examination of the time variations of these non-potential and volume-threading helicities. The validity of the analytical formulas derived are confirmed with analysis of three- dimensional (3D) magnetohydrodynamics (MHD) simulations of solar coronal dynamics.

Launching a New Era of Exploration Welcome to Langley NASA Langley had a banner year in 2012 as we helped propel the nation toward a new age of air and space. From delivering on missions to creating new technologies and knowledge for space, aviation and science, Langley continued the rich tradition of innovation begun 95 years ago. Langley is providing leading-edge research and game-changing technology innovations for human space exploration. We are testing prototype articles of the Orion crew vehicle to optimize designs and improve landing systems for increased crew survivability. Langley has had a role in private-industry space exploration through agreements with SpaceX, Sierra Nevada Corp. and Boeing to provide engineering expertise, conduct testing and support research. Aerospace and Science With the rest of the world, we held our breath as the Curiosity rover landed on Mars – with Langley’s help.

The new office will: 1.Support research in new technologies to increase public participation. 2.Coordinate NASA-wide efforts to ensure that Participatory Exploration activities are included in future missions. The Office also will coordinate and promote the inclusion of participatory exploration activities in other Agency projects, outreach and education practices. 3.Act as a clearinghouse for identifying and communicating best practices in Participatory Exploration. 9/14/10 Participatory Exploration 2 Participatory Exploration Participatory Exploration is the active involvement of individuals in the experience of, as contributors to, and collaborators in, NASA’s research, science and discovery activities. Participatory Exploration will foster, facilitate and support active public engagement and collaboration by combining improved technology and Open Government practices to provide a spectrum of engagement possibilities. Participatory Exploration will increase: •Opportunities for personal connections with NASA and its missions; What is in it for the Society? •Public interest in STEM; What can NASA do to benefit Society? •NASA’s access to the interest, knowledge, skills, creativity and innovation that exists outside the NASA community.

Lin, Co-chair Doctor S¨am Krucker, Co-chair Professor Stuart D. Bale, Co-chair Solar flares are huge explosions on the Sun that release a tremendous amount of energy from the coronal magnetic field, up to 1033 ergs, in a short time (100–1000 seconds), with much of the energy going into accelerated electrons and ions. An efficient acceleration mech- anism is needed, but the details of this mechanism remain relatively unknown. A fraction of this explosive energy reaches the Earth in the form of energetic particles, producing geomag- netic storms and posing dangers to spaceborne instruments, astronauts, and Earthbound power grids. There are thus practical reasons, as well as intellectual ones, for wishing to understand this extraordinary form of energy release. Through imaging spectroscopy of the hard X-ray (HXR) emission from solar flares, the behavior of flare-accelerated electrons can be studied.
