CAWSES, ILWS, IHY, eGY, ICESTAR Sun-Earth Science eWorkshop Joining Observations from the HPS Great Observatory with Worldwide Satellite and Ground-Based Resources J U Kozyra, K Shibata, R J Barnes, S Basu, J M Davila, N J Fox, N Gopalswamy, M M Kuznetsova, D Pallamraju, L J Paxton New Co-Author: C. Alex Young Our Goal is to Identify the “Grand Challenges” in Heliophysics We plan to hold a virtual workshop in September 2006. This workshop is a stepping stone toward enabling the community to address “Grand Challenges” We want to identify important science questions. We want to identify the technology that must be present in our to carry out the workshop. What works? How well does it work? What more do we need? Our goal is not to run another event study. Our goal is to define those problems and locate and analyze the data that enable us to address grand challenges in the study of the interaction of the Sun and Earth. In the following slide we provide an example of an event. Example: Initial Look at Events During Related to CAWSES Campaigns WHAT HAPPENED? Example: Initial Look at Events During Related to CAWSES Campaigns PRELIMINARY ANALYSIS AR 798 anemone active region. [Ayumi Asai, NSRO, 2005] Produced CME with high velocity; high dynamic pressure in the sheath A major substorm was triggered just as the IMF Bz reached it’s minimum values Unusual auroral oval configuration with large vortex on the dawn side and double oval structures (possibly another vortex) on the duskside. Thick nightside oval very thin dayside oval. [Kozyra et al., Spring AGU, 2006] Evidence for new type of storm-substorm coupling What is the state of the Sun-Earth System during Extreme Events? SUN HELIOSPHERE What effect does close proximity to an active region have on the release propagation of CMEs? Does an active region leave a “fingerprint” on the CMEs? Do they have common characteristics? How important were propagation? MAGNETOSPHERE How important is
