SOON consists of up to five US Air Force Air Weather Service observatories. The Air Force operates five solar telescopes distributed in longitude to maintain continuous coverage to monitor solar active regions at optical wavelengths. GDC archives histograms of intensity versus area every minute for the active regions as well as magnetograms of the magnetic field structure and tachograms of plasma velocities on an irregular schedule. The basic SOON telescope is a 25-centimeter evacuated refractor mounted on a polar axis. It has a tunable monochromatic filter centered on the hydrogen-alpha absorption line (6562.8A) of the solar spectrum. Shifting the filter characteristics slightly off center from the H-alpha peak results in pictures of the solar surface region at differing depths. Corresponding to the optical images of solar regions are the digital "brightness-area" data. These data are often plotted as brightness-area histograms for a particular time or, in a 3-3-dimensional display, showing a time sequence of changing intensity of optical emissions from areas of solar active regions. Each digital scan of a region describes the amount of solar surface area within a pre-set rectangular viewing grid that is of brightness level N, where N ranges from 1 to 64 and represents the gray scale range from black to white. The automatic capability of the SOON telescope system allows the rapid collection of this brightness-area information on many active regions on the sun. By using these data, quantitative measures, including instability, growth/decay rates, and precise areas for each active solar region, can be determined. purpose: Solar Research status: (MD_ProgressCode) underDevelopment pointOfContact: (CI_ResponsibleParty) individualName: Solar Data Manager organisationName: DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce contactInfo: (CI_Contact) phone: (CI_Telephone) voice: 303.497.6133 or 303.497.6323 facsimile: (303) 497-6513 address: (CI_Address) deliveryPoint: NOAA/NESDIS/NGDC E/GC2 325 Broadway city: Boulder administrativeArea: CO postalCode: 80305 country: USA electronicMailAddress: solar.ngdc@noaa.gov hoursOfService: 7:30 - 4:30 Mountain contactInstructions: Contact Data Center role: (CI_RoleCode) pointOfContact resourceMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) monthly graphicOverview: (MD_BrowseGraphic) fileName: SOON drawing from the Boulder Station fileDescription: ftp://ftp.ngdc.noaa.gov/STP/SOLAR_DATA/SOLAR_IMAGES/BoulderSunspotDrawings/1990/19900120.jpg fileType: jpg descriptiveKeywords: (MD_Keywords) keyword: EARTH SCIENCE > SOLAR PHYSICS > Solar Activity > Sunspots keyword: EARTH SCIENCE > Sun-earth Interactions > Solar Activity > Solar Active Regions keyword: EARTH SCIENCE > Sun-earth Interactions > Solar Activity > Solar Imagery type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: NASA/Global Change Master Directory (GCMD) Earth Science Keywords date: (CI_Date) date: 2007-04 dateType: (CI_DateTypeCode) revision edition: Version 6.0.0.0.0 editionDate: 2007-04 citedResponsibleParty: (CI_ResponsibleParty) organisationName: 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 contactInfo: (CI_Contact) onlineResource: (CI_OnlineResource) linkage: http://gcmd.gsfc.nasa.gov/Resources/valids/archives/keyword_list.html protocol: http applicationProfile: web browser name: GCMD Keywords, Version 6.0.0.0.0 description: Thesuarus for earth science keywords and associated directories hosted and maintained by NASA. function: (CI_OnLineFunctionCode) information role: (CI_RoleCode) resourceProvider descriptiveKeywords: (MD_Keywords) keyword: Solar Physics keyword: Magnetograms keyword: Sunspots keyword: Solar Flares keyword: Tachograms type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: Uncontrolled Keywords date: descriptiveKeywords: (MD_Keywords) keyword: WDC/STP, BOULDER > World Data Center for Solar-Terrestrial Physics, Boulder keyword: DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: NASA/GCMD Data Center Keywords date: descriptiveKeywords: (MD_Keywords) keyword: Photosphere type: (MD_KeywordTypeCode) place thesaurusName: (CI_Citation) title: NASA/GCMD Location Keywords date: descriptiveKeywords: (MD_Keywords) keyword: Sun type: (MD_KeywordTypeCode) place thesaurusName: (CI_Citation) title: Uncontrolled Location Keywords date: resourceConstraints: (MD_LegalConstraints) accessConstraints: (MD_RestrictionCode) otherRestrictions useConstraints: (MD_RestrictionCode) otherRestrictions otherConstraints: 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. language: eng;
