January 3, 2008 Space Weather Prediction Center SOLAR AND GEOPHYSICAL ACTIVITY SUMMARY (SGAS) The daily Solar and Geophysical Activity Summary is a brief list of solar and geophysical events and indices for the previous UTC day, including energetic solar flares, proton events, geomagnetic activity, and stratospheric warming alerts. See sample and description below. The last 75 Reports are available in this directory. Issue time: Daily at 0245 UTC, usually online at 0250 UTC. Period covered: Previous UTC day.

Comments: None ========================================================= Description: Part A. A profile of significant solar events including start, maximum, and end times, region number and location, x-ray and optical classification of flares, significant radio emission at 245 MHz, 10 cm (2695 MHz), and sweep frequencies, and significant short wave fades. All available data for an event are included in this section if one or more of the following thresholds are reached: Class-M or greater x-ray flare, Optical flare of importance > 2B, Radio burst of > 100 sfu at 245 MHz, Radio burst > 100% above background at 2695 MHz, Type II or IV sweep frequency burst, Shortwave fade of importance 2 or greater. Part B. Proton event data given whenever the flux of >10 MeV protons reaches or exceeds 10 particle flux units (pfu). Data include start, maximum, and end times for events at >10, 50, and 100 MeV. Part C. A summary of the geomagnetic field during the previous UTC day. Part D. Stratospheric warming alerts -- not available to SWPC after Dec 1, 2004. Part E. Indices about the previous UTC day: Observed 2000 UTC Penticton 10.7 cm flux, SEC sunspot number (SSN), Estimated geomagnetic AFr-index, Estimated planetary AP-index, Daily x-ray background flux expressed in B, C, M, X scale (W m-2), Daily proton fluence (flux accumulation over 24 hours) for >1 MeV and >10 MeV protons at geosynchronous altitudes, 3-hourly KB-indices (Boulder) and estimated KP-indices (Planetary). Part F. Reserved for additional comments as required. ======================================================================== ======================================================================== ======================================================================== OLD NOTICES November 24, 2004 Stratwarm alert service provided by SEC ends Dec 1 2004. SEC was informed that the Free University of Berlin (FUB) will no longer issue stratwarm alerts which were included in SGAS reports. The daily development of the stratospheric circulation can still be found on the FUB web site (http://strat-www.met.fu-berlin.de/). The general evaluation is, however, left to the user. May 15, 2003 GOES-8 became the primary satellite for protons. GOES 12 is the primary satellite for magnetometer, X-ray, and electron measurements. GOES 10 is the secondary satellite for all SEM sensors - magnetometer, X-ray sensor, and energetic particle sensor. This short-term solution (approximately 2 - 3 months) will be in place until we define and implement a permanent fix.
