These professional drawings ensure the forecasters have a comprehensive view of all relevant solar features. Daily drawings are available back to June 2, 1972 and are still being produced today. The drawing show features such as neutral lines, coronal hole boundaries, active regions, plage, filaments and prominences. Also included are specific information about coronal hole polarity, active region numbers, flare probabilities for each region and proton event probabilities for each region. The National Geophysical Data Center provides these drawings both as pdf images, available online, or as high-resolution tif images available by request.The NGDC Solar and Terrestrial Physics (STP) division provides scientific data stewardship of solar-terrestrial datasets in compliance with NOAA Administrative Order (NAO) 212-12, "Management of Environmental and Geospatial Data and Information", dated 04 Nov 10. Scientific Data Stewardship includes the Archive, Access, and Assessment (AAA) of operational and related solar and space environmental datasets.1972060220111231UnknownIn workannually-18018090-90NASA/GCMD Earth Science Keywords; Olsen, L.M., G.
