Abstract:

LONG-TERM GOAL. Our major goal is to improve the accuracy and timeliness of solar magnetic field data that are used to predict space weather disturbances that affect Earth. SCIENTIFIC OBJECTIVES. The primary objectives are to provide best estimates of the magnetic flux distribution along the central meridian of the sun as a function of time and also best estimates of the magnetic flux over the entire surface of the sun at specified instants of time. These data are required as boundary conditions for numerical models that are used to predict space weather conditions. Our secondary objectives are to explore poorly understood aspects of the solar magnetic field that may have future significance in understanding space weather. The specific targets are the polar magnetic field, the intranetwork magnetic field, and field configurations associated with coronal mass ejections.
