The NSSDC Coordinated Heliospheric Observations Web, COHOWeb, hourly and daily Solar-Terrestrial Relations Observatory-A, STEREO-B, data were made by using high resolution data from from CDAWeb. The STEREO-A COHO file include data derived from the STEREO-A In-Situ Measurements of Particles and CME Transients, IMPACT, Fluxgate Magnetometer data, Thermal Plasma Moments: Solar Wind Proton and Ion Densities, Speeds, Velocity Vector Flow Angles, and Temperatures from the STEREO-A Plasma and Supra-Thermal Ion Composition, PLASTIC, Instrument, and Energetic Particle Fluxes from the STEREO-A IMPACT Solar Energetic Particle, SEP, Instrument Suite including the Low Energy Telescope, LET, High Energy Telescope, HET, and Suprathermal Ion Telescope, SIT. COHOWeb's magnetic field hourly averages were created at GSFC/SPDF by averaging over the six 10-min averages falling within each hour. Hourly plasma parameter data were obtained from UNH via http://fiji.sr.unh.edu/1dmax_ascii/.

Plot and list heliocentric orbit information for spacecraft remote from Earth and for planets having heliophysics spacecraft in orbit about them. Underlying data files contain heliocentric distances and elevation and longitude angles at daily resolution. The Space Physics Data Facility (SPDF) is the archive of non-solar data for the Heliospheric Science Division (HSD) at NASA's Goddard Space Flight Center.

The Multi Element Telescope for Imaging and Spectroscopy, METIS, investigation has been conceived to perform off-limb and near-Sun coronagraphy and is motivated by the aim of addressing the three key scientific questions identified as the focus of the HELEX program. These questions concern: the origin and heating/acceleration of the solar wind streams; the origin, acceleration and transport of the solar energetic particles; and the transient ejection of coronal mass and its evolution in the inner heliosphere (coronal mass ejections, CME’s).

The investigation aims to provide crucial tests apt to verify the hypotheses and models on the following main issues of solar coronal physics that have been developed primarily during the SOHO era:

• Is the slow solar wind originating according to more than one physical process and which is the level of contribution of the possible different sources of slow wind to the heliospheric wind observed ‘in situ’?

• How does the magnetic field topology control the outflow velocity and composition of the slow and fast solar wind?

• Is the magnetic field controlling the emergence of the fast wind at the base of coronal holes?

• Do polar plumes and inter-plume regions have a role in channeling the fast wind?

• Is ion cyclotron dissipation of fast Alfvén waves the primary energy deposition process in the fast wind? • Is the reconnection at the base of coronal holes responsible for the generation of waves and turbulence that energize the fast wind?

• Which is the nature of coronal heating in open and closed field regions?

• Which is the source of the seed particles of the Solar Energetic Particles (SEPs)?

• Which is the role of coronal shocks driven by coronal mass ejections in energizing SEPs? • Which are the mass and magnetic fluxes carried out from the Sun during transient events?

• How does the evolution of the coronal magnetic field, inferred from the large-scale evolution of the outer corona, trigger coronal mass ejections?

• How does the corona re-adjust after coronal mass ejections on medium-term time scales, ranging between 3 and 10 days (not yet established in the outer corona)?

• How do the quiescent streamers evolve on time scales ranging between 3 and 10 days? The crucial tests for addressing and solving these still open issues can be achieved by combining the instrument’s versatility with the uniqueness of the Solar Orbiter mission profile, which allows: a close approach to the Sun thus leading to a significant improvement in spatial resolution; quasi co-rotation with the Sun, which allows to nearly freeze for several days both the on-disk inner corona and the outer corona in the plane of the sky and, thus, disentangle the evolution of coronal structures and solar rotational effects on medium-term time scales, an outof- ecliptic view of the Sun. METIS instrument is designed to combine and extend the imaging and spectroscopic capabilities of the SOHO and STEREO coronagraphs and spectrometers in order to exploit at  

Display and download orbit and trajectory data for most heliophysics missions. The Satellite Situation Center (SSC) also enables complex queries between spacecraft and ground locations, tracing along magnetic field lines, and geophysical regions of space. The Space Physics Data Facility (SPDF) is the archive of non-solar data for the Heliospheric Science Division (HSD) at NASA's Goddard Space Flight Center.

The National Space Science Data Center serves as the permanent archive for NASA space science mission data. 'Space science' means astronomy and astrophysics, solar and space plasma physics, and planetary and lunar science. As permanent archive, NSSDC teams with NASA's discipline-specific space science 'active archives' which provide access to data to researchers and, in some cases, to the general public. Search by event, spacecraft, experiment, map, or publication query. NSSDC is part of the Solar System Exploration Data Services Office (SSEDSO) in the Solar System Exploration Division at NASA's Goddard Space Flight Center in Greenbelt, MD.

We propose to observe the solar upper transition region and lower corona in Ne VII 46.5 nm with the Multi-Order Solar EUV Spectrograph (MOSES) rocket payload. The solar plasma in this temperature range, about 500,000 K, has not been imaged at rapid cadence since Skylab (Feldman, 1987). The unique observational capabilities of MOSES, demonstrated already in He II 30.4 nm, enable simultaneous imaging and measurement of line widths and doppler shifts over a large (20’ x 10’) field of view, with typical active region exposure times of 10 s. These observations will reveal the 3D dynamics of outflows and reconnection events in active regions, quiet Sun, and coronal holes. The primary objectives of this one-year proposal are (1) instrument calibration, (2) launch of the rocket in summer of 2012, and (3) data analysis, including exploration of new techniques to recover more spectral information from the MOSES data. Prior NASA funding has enabled data analysis and publication of results from the first flight, upgrades to the payload, and increased reliability of our ground support equipment. Procurement of optics to observe the Ne VII 46.5 nm line is in process. With the help of additional funding from Montana Space Grant Consortium, we have also developed an EUV calibration facility optimized for testing the MOSES payload.
