AbstractThe Whole Heliosphere Interval is an international observing and modeling effort to characterize the three-dimensional interconnected solar-heliospheric-planetary system, i.e., the “heliophysical” system. WHI was part of the International Heliophysical Year, on the 50th anniversary of the International Geophysical Year, and benefited from hundreds of observatories and instruments participating in IHY activities. WHI describes the 3-D heliosphere originating from solar Carrington Rotation 2068, March 20–April 16, 2008. The focus of IAU JD16 was on analyses of observations obtained during WHI, and simulations and modeling involving those data and that period. Consideration of the WHI interval in the context of surrounding solar rotations and/or compared to last solar minimum was also encouraged. Our goal was to identify connections and commonalities between the various regions of the heliosphere.

The International Heliophysical Year (IHY) is an international program of scientific research and collaboration to understand the external drivers of the space environment and climate. Its activities were centered on the year 2008, the 50th anniversary of the International Geophysical Year. The IHY involves utilizing the existing assets from space and ground as a distributed Great Observatory and the deployment of new instrumentation, new observations from the ground and in space, and public and student education. The IHY officially was launched in February 2007 with an opening ceremony and workshop in Vienna. Many IHY activities, both scientific and educational, have occurred since then. In practice, these activities have taken place over the last several years, and the programs that have been established through the IHY will continue into the future as ‘legacies’ of the IHY.

2009 brings not only the 50th anniversary of the Antarctic Treaty but also the end of the International Geophysical Year (IGY) and of its extension into the period of International Geophysical Cooperation (IGC 1959). It is also the 133rd anniversary of K. Weyprecht's suggestion that initiated the impetus. As he noted, ‘if Polar Expeditions are looked upon merely as a sort of international steeple-chase . . . and their main object is to exceed by a few miles the latitude reached by a predecessor these mysteries (of Meteorology and Geomagnetism) will remain unsolved’ (Weyprecht 1875). Although he stressed the importance of observations in both the Arctic and Antarctic during the first International Polar Year (IPY) in 1882–1883 only two stations in the sub-Antarctic region, at Cap Horn and South Georgia, made such scientific recordings. In spite of the fact that several expeditions to the Antarctic had been made in the period between the first and the second IPY 1932–1933, no stations were created in Antarctica during that IPY. The major increase in scientific studies in Antarctica came with the third IPY, which became the IGY of 1957–1958.

AbstractWe present a summary of results from simultaneous Solar-Terrestrial Environment Laboratory (STELab) Interplanetary Scintillation (IPS), STEREO, ACE, and Wind observations using three-dimensional reconstructions of the Whole Heliosphere Interval – Carrington rotation 2068. This is part of the world-wide IPS community's International Heliosphysical Year (IHY) collaboration. We show the global structure of the inner heliosphere and how our 3-D reconstructions compare with in-ecliptic spacecraft measurements.
