Observations for the Third Whole Sun Month Campaign were made throughout Carrington Rotation 1953 (August 18-September 14, 1999). As in the first campaign; the primary focus is on understanding the large scale solar corona and the connections to interplanetary space over a full solar rotation. The fundamental notion of these campaigns is that the observations are available for anyone to work with. In this poster, we use synoptic maps to show the morphology of the solar corona during CR1953 at a variety of wavelengths, heights, and temperatures. Data are shown from YOHKOH SXT, MLSO Mk4, and SOHO MDI, CDS, UVCS, EIT, and LASCO. The current campaign differs from the first campaign in that near solar maximum conditions prevailed. We held one workshop in order to get organized and begin collaborations. The planned studies will include determining the plasma parameters in various coronal structures and in modeling the structure of the coronal magnetic fields. In addition, we had the opportunity to study how a "sigmoidal" active region evolved as it crossed the solar disk and affected the global corona through a series of flares and eruptive events, and to obtain detailed observations of its structure over a wide range of heights and temperatures. We will be holding future workshops to analyze the data and work on models. We invite you to participate in this campaign or at least see our current plans for data analysis and modeling.
