SOLAR AND GEOPHYSICAL ACTIVITY SUMMARY (SGAS)
==========================================================================
GOES 14 Primary Satellite for XRS data
December 1, 2009: SGAS shows GOES 14 X-ray Background.
GOES 11 continues for Proton and Electron Fluence.
==========================================================================
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.

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
==========================================================================
GOES 10 Decommissioning Dec 1, 2009
GOES 14 Becomes Primary Satellite for XRS data
November 17, 2009: On Tuesday, 01 December, the GOES 10 satellite will
be officially decommissioned. At that time, GOES 14 will replace GOES 10
as the Primary SWPC GOES X-ray Satellite.
The Solar And Geophysical Activity Summary show GOES 14 X-ray Background.
Proton and Electron Fluence will continue to be from GOES 11.
==========================================================================
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.
