On March 12 eclipse times are at maximum (0839 to 0944 UT). GOES 11 eclipse season ends April 10. Feb 21, 2008 -- GOES 10 X-ray outages due to spacecraft eclipse season started Feb 20 and will end April 5. Maximum eclipse duration will reach about 65 minutes peaking in the middle of the interval (March 11). Currently, X-ray sensors (XRS) are not operational on other GOES satellites to fill in for the GOES-10 eclipses. February 10, 2008 -- GOES-10 satellite tracking at SWPC resumeed. =========================================================================== =========================================================================== =========================================================================== 2007 Five Ionosonde Stations Added In January December 28, 2007 -- Five additional Ionosonde Stations are being added in the Daily Ionospheric Data Lists directory in early January. ftp.swpc.noaa.gov cd to /lists/iono_day/ http://www.swpc.noaa.gov/ftpmenu/lists/iono_day.html =========================================================================== December 18, 2007 -- GOES-10, the SWPC secondary GOES Satellite for X-ray and Proton data, is again not being tracked at SWPC due to an antenna problem. December 5-17, 2007 -- GOES 10 tracking was restarted during GOES 12 outage. November 21 - Dec 5, 2007 -- GOES-10, the SWPC secondary GOES Satellite for X-ray and Proton data, was not tracked at SWPC due to an antenna problem. =========================================================================== GOES-11 Electron Fluence Data Dec 5-17, 2007 Dec 18, 2007 -- GOES 12 Electron Fluence data was unavailable from Dec 5 - 17. During this time the Daily Particle Data files have missing, or partial, data for the GOES-12 Electron Fluence values. Below are the GOES-11 Electron Fluence values for the missed dates. When the 2007 Daily Particle Data file is created in early 2008 the missed data with be replaced with GOES-11 values so the archived list is complete. # GOES-11 Proton Fluence GOES-11 Electron Fluence Neutron # --- Protons/cm2-day-sr --- -- Electrons/cm2-day-sr -- Monitor # Date >1 MeV >10 MeV >100 MeV >0.6 MeV >2 MeV % of bkgd #------------------------------------------------------------------------------- 2007 12 05 1.0e+06 1.9e+04 4.4e+03 1.0e+10 3.5e+07 100.39 2007 12 06 1.1e+06 1.9e+04 4.4e+03 6.9e+09 2.1e+07 100.15 2007 12 07 9.2e+05 1.8e+04 4.7e+03 6.4e+09 2.3e+07 100.15 2007 12 08 1.3e+06 1.9e+04 4.6e+03 6.3e+09 2.7e+07 99.90 2007 12 09 8.8e+05 1.9e+04 4.6e+03 4.6e+09 2.1e+07 99.90 2007 12 10 1.4e+06 1.9e+04 4.2e+03 1.5e+09 4.2e+06 99.80 2007 12 11 2.1e+06 1.8e+04 3.9e+03 9.0e+09 4.3e+06 99.50 2007 12 12 1.1e+06 1.8e+04 3.8e+03 2.8e+10 2.8e+07 99.60 2007 12 13 5.9e+05 1.7e+04 3.8e+03 4.3e+10 6.6e+07 99.60 2007 12 14 9.0e+05 1.7e+04 3.8e+03 4.2e+10 7.9e+07 99.90 2007 12 15 9.8e+05 1.7e+04 3.9e+03 3.5e+10 6.6e+07 100.26 2007 12 16 1.1e+06 1.8e+04 4.1e+03 2.9e+10 5.5e+07 99.90 2007 12 17 2.1e+06 1.7e+04 3.9e+03 1.1e+10 1.0e+07 99.70 =========================================================================== GOES 12 Outage Dec 5-17, 2007 December 17, 2007 -- GOES 12 was unavailable from December 5, 1010UT until 2040UT December 17, 2007. =========================================================================== Space Environment Center (SEC) Changes Name to Space Weather Prediction Center (SWPC) On October 1, 2007 the NOAA Space Environment Center changed its name to the Space Weather Prediction Center (SWPC). The center is one of the nine National Centers for Environmental Prediction (NCEP) within NOAA's National Weather Service. The new name aligns the space weather center with the other NCEP centers and more clearly conveys its operational nature. SWPC.noaa.gov is the new domain for web access (www.swpc.noaa.gov) and Anonymous FTP. The old domain, sec.noaa.gov, will continue to work for the foreseeable future. The simple web URL spaceweather.gov is also available. The new name began appearing in web pages and product headers October 1. Web pages use NOAA web formatting standards and some have an updated look and feel, but the data displays and content did not change. Text and graphical products headers use Space Weather Prediction Center (or SWPC), but there were no changes to the file formats or content. ========================================================================= USAF Products Delayed Aug 28, 2007 -- 1945UT Routine USAF product transfers to SEC are disrupted and a temporary work-around has been implemented. Estimated Planetary A and K indices, and Daily Solar Radio Noon Flux values, from Aug 28 0000UT through 1400UT are still unavailable. USAF products are now being received, but may be delayed. Currently there is no estimate when the primary failure will be repaired. ======================================================================= ======================================================================= ======================================================================= ======================================================================= 2006 GEOMAGNETIC STORM IN PROGRESS 2006 December 14 1704 UTC A geomagnetic storm began on December 14 at 1416 UTC (9:16 A.M. EST). A solar flare on 13 December at 0240 UTC (12 December, 9:40 P.M. EST) from NOAA Region 930 produced strong radio blackouts (R3) and an associated moderate (S2) solar radiation storm. A large Earth-directed coronal mass ejection was also observed with this event, producing today's geomagnetic storming. Strong to severe (G3 & G4) geomagnetic storming is expected to last through 15 December. Region 930 is a large sunspot group which is still rotating across the visible disk. Because of the current position of Region 930, additional activity has greater potential to quickly impact Earth. Agencies impacted by space weather storms should continue to closely monitor space weather conditions during the next four days. ======================================================================= ACE SOLAR WIND DATA CONTAMINATED December 13, 2006 Recent solar energetic proton events contaminated the ACE SWEPAM instrument data resulting in incorrect solar wind density, speed, and temperature values being reported by SEC. The latest contamination started at about 0340 UTC on 13 December and ended at about 2000 UTC 13 December as energetic proton fluxes subsided. ACE RTSW MAG, EPAM, and SIS data were unaffected. ================================================================== SEC Anonymous FTP Service Hosted by NWS November 2, 2006 -- Beginning today, the National Weather Service (NWS) is hosting the SEC Anonymous FTP service ftp.swpc.noaa.gov. The NWS provides a dedicated, high-availability environment which increases reliability and capacity. No product changes where made. Connections to SEC using IP addresses no longer work. Please use the domain name: ftp.swpc.noaa.gov ftp2.sec.noaa.gov, the SEC backup Anonymous FTP server, is not needed in the new environment and has been discontinued. ================================================================== HTTP Alternative to Anonymous FTP SEC Anonymous FTP content is accessible through the http URL http://www.swpc.noaa.gov/ftpdir/ There are a number of software packages that support automatic connections and retrieval such as GNU Wget GNU Wget, http://www.gnu.org/software/wget/ is a free software package for retrieving files using HTTP, HTTPS and FTP. Its a non-interactive command line tool, so it may be called from scripts, cron jobs, terminals without X-Windows support, etc. GNU Wget has many features to make retrieving files from web or FTP sites easy. For more details and an SEC example see: http://www.sec.noaa.gov/Data/about_data.html#wget ======================================================================== Special Web and FTP access ends September 18, 2006 http://solar.sec.noaa.gov http://dawn.sec.noaa.gov ftp solar.sec.noaa.gov ftp dawn.sec.noaa.gov August 17, 2006 -- Access to SEC web and ftp servers through the above special addresses ended September 18, 2006. Customers are advised to switch to the official addresses: ======================================================================== SEC Secondary GOES Spacecraft Change At 1400UT, June 22, 2006 the SEC secondary GOES satellite for magnetometer, X-ray, and electron measurements changed from GOES 10 to GOES 11. GOES 12 remains the primary SEC GOES satellite. For energetic proton measurements there was no change; GOES 11 remains the primary SEC GOES satellite and GOES 10 the secondary. SEC products that include magnetometer, X-ray, and electron measurements from the secondary SEC GOES satellite changed at that time. ======================================================================== GOES 10 Energetic Proton Outages Expected June 26, 2006 -- GOES 10, SEC's secondary GOES satellite for energetic protons, will not be available at SEC for about two weeks beginning on June 23, because its telemetry frequency will be changed to avoid conflicting with GOES 11 transmissions. There will be two additional periods (approximately 10 - 14 days) when GOES 10 data will not be available, as GOES 10 drifts past GOES 13 and GOES 12. GOES 11, the primary SEC GOES satellite for Energetic Protons will be available throughout the GOES 10 outages. ================================================================== June 15, 2006 Using GNU Wget to Retrieve SEC Web and FTP Files GNU Wget, http://www.gnu.org/software/wget/ is a free software package for retrieving files using HTTP, HTTPS and FTP. Its a non-interactive command line tool, so it may be called from scripts, cron jobs, terminals without X-Windows support, etc. GNU Wget has many features to make retrieving files from web or FTP sites easy.
