June 1, 2010 Space Weather Prediction Center GEOALERT ========================================================================== Thule Neutron Monitor Daily Percent of Background Discontinued June 1, 2010 SWPC discontinued the Daily Thule Neutron Monitor data in the GEOALERT UGEOI message. The ground-level cosmic ray intensity and events group in the UGORI coded message are now always 4////. For more details, alternative sources, and SWPC contact information. See http://www.swpc.noaa.gov/Thule.html ========================================================================== The GEOALERT message contains four coded messages and sometimes plain text. UGEOA: The World Warning Agency (WWA) consensus forecast for 1- to 3-day forecasts of whole-disk flares, geomagnetic activity, and protons. UGEOE: A summary of significant solar events for the previous day UGEOI: Observed solar-geophysical indices for the previous day UGEOR: Sunspot data for the previous day, and regional forecasts See sample and description below. This message is a consensus of the Advices received from the seven Regional Warning Centers (RWCs) of the IUWDS (International Ursigrams and World Days Service). These centers are located in Paris, Beijing, Moscow, Darmstadt, Tokyo, Sydney, and Boulder. In addition to being one of the RWCs, Boulder is also the IUWDS World Warning Agency (WWA) responsible for collecting and coordinating daily forecasts, alerts, and encoded solar-terrestrial data. The GEOALERT message, and other URSI coded messages transmitted on the COMEDS teletype network, are described in detail in the manual I.U.W.D.S. Synoptic Codes For Solar And Geophysical Data, written by SESC. The last 75 reports are included in this directory. Issue time: Daily at 0330 UTC Period Covered: Previous UT day and forecast day.

Codes begin with a five-letter code word (UGEOA, UGEOE, UGEOI, or UGEOR) indicating how the numbers that follow should be interpreted. Instructions for decoding the GEOALERT message are in the manual I.U.W.D.S. Synoptic Codes For Solar And Geophysical Data, written by SESC. In summary, the codes contain for following information. See Code Book at http://www.ises-spaceweather.org/ UGEOA: The World Warning Agency (WWA) consensus forecast for 1- to 3-day forecasts of whole-disk flares, geomagnetic activity, and protons. UGEOE: A summary of significant solar events for the previous day using the following criteria: M-class or greater x-ray flare Optical flares of importance 2B or greater Radio bursts - 100 sfu at 245 MHz Radio bursts - 100% above background at 10 cm Type-II or Type-IV sweep-frequency burst UGEOI: Observed solar-geophysical indices for the previous day, including: Daily SESC sunspot number and area AB Index Ground-level cosmic ray intensity and events (ended 01 June 2010) Daily 10.7 cm radio flux from Penticton, Canada Total M- and X-class x-ray flares X-ray background level Particle fluence (>10 MeV) Total number of regions with sunspots Number of new regions with sunspots UGEOR: Sunspot data for the previous day, and regional forecasts including: Region number and location Number of optical, M- and X-class x-ray flares for the region Sunspot classification and total sunspot area Number of spots in the region Flare probability forecast for the region PLAIN: Plain-language remarks added as necessary; for example, it may describe international observing programs such as FLARES 22/Max'91. ========================================================================== ========================================================================== ========================================================================== OLD NOTICES ========================================================================== Thule Neutron Monitor Daily Percent of Background To Be Discontinued April 20, 2010 -- On 01 June, SWPC will discontinue the Daily Thule Neutron Monitor data in the GEOALERT UGEOI message. The ground-level cosmic ray intensity and events group in the UGORI coded message will be 4////. For more details, alternative sources, and SWPC contact information.
