    Other Research Goals: The project is to look at structure in the solar wind coordinated with structure on the sun. The temporal structures of interest in the solar wind have timescales of about hour as they sweep past ACE and Wind; the structures on the sun are magnetic-carpet filaments about the size of solar granules.
    The goal is to obtain a number of simultaneous observations of a small region of the sun, the Earth's footpoint. The idea is to coordinate analysis of magnetic-carpet observations, granulation observations, etc. with observations of the solar wind that came from that region. The footpoint location will be determined just prior to the telescope observations by the Wang-Sheeley-Arge method. We are thinking of Hinode, Trace, EIT high resolution, MDI, ground-based observation of the photosphere, ground-based helium observations, and GONG. See WHI Quiet Sun campaign.
    We are planning to propose for about 5 observing intervals that are separated from each other by at least a day. We have not decided how long the intervals need to be (probably depends on the instrument), but 2 hours or less is anticipated.
