The corona is observed in detail during solar eclipses. In practice, the corona is observed routinely by ground-based and satellite coronagraphs in the red line Fe X (634.7nm -- ten times ionized iron line) and the green line Fe XIV (530.3 nm -- 14 times ionized iron line), and occasionally in the high energy yellow line Ca XV (569.4 nm -- 15 times ionized Calcium line). White light observations of the solar corona are also made routinely, and used for detecting coronal mass ejections (CMEs) that may affect the Earth. The coronagraph is a special telescope with an occulting disk to block the direct light of the sun and thus able to measure the brightness of the fainter and less dense corona. The intensities are recorded in tabular form, historically in 5-degree increments around the sun's disk. The data center holds data in analog form from 12 stations covering the period 1943 to present. Currently, 2 stations send daily coronal scans to the data center. A coronal activity index from Lomnicky Stit, Slovak Republic, 1939-present, is also available. Coronal data exhibit the 11 year solar cycle variation. Solar X-ray measurements since 1991 by the Yohkoh and GOES Solar X-ray Imager (SXI) satellites allow continuous coverage of the constantly changing hot solar corona. To provide long-term scientific data stewardship for the Nation's geophysical data, ensuring quality, integrity, and accessibility. underDevelopment Solar Data Manager DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce 303.497.6133 or 303.497.6323 (303) 497-6513 NOAA/NESDIS/NGDC E/GC2 325 Broadway Boulder CO 80305 USA solar.ngdc@noaa.gov 7:30 - 4:30 Mountain Contact Data Center pointOfContact asNeeded Earth Science > Sun-Earth Interactions > Solar Activity > Corona Holes Earth Science > Sun-Earth Interactions > Solar Activity > Coronal Mass Ejections Earth Science > Sun-Earth Interactions > Solar Activity > Coronal Properties theme NASA/Global Change Master Directory (GCMD) Earth Science Keywords 2007-04 revision Version 6.0.0.0.0 2007-04 NASA/GSFC/SED/ESD/GCDC/GCMD > Global Change Master Directory, Global Change Data Center, Earth Sciences Division, Science and Exploration Directorate, Goddard Space Flight Center, NASA http://gcmd.gsfc.nasa.gov/Resources/valids/archives/keyword_list.html http web browser GCMD Keywords, Version 6.0.0.0.0 Thesuarus for earth science keywords and associated directories hosted and maintained by NASA. information resourceProvider Coronal Holes Coronal Scans Green Line Emission Solar Physics theme Uncontrolled Keywords WDC/STP, BOULDER > World Data Center for Solar-Terrestrial Physics, Boulder DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce dataCenter NASA/GCMD Data Center Keywords Space > Solar Region > Corona place NASA/GCMD Location Keywords otherRestrictions otherRestrictions Access Constraints: No Constraints Use Constraints: None Distribution Liability: While every effort has been made to ensure that these data are accurate and reliable within the limits of the current state of the art, NOAA cannot assume liability for any damages caused by any errors or omissions in the data, nor as a result of the failure of the data to function on a particular system.
