Space Weather Event Reports
This directory contains the last 75 Summary of Space Weather Event
Reports issued.
Issue time: Daily after 0250 UTC, usually online by 0300 UTC.
Period covered: Previous UTC day.
Description:
The Summary of Space Weather Observations is a daily report of
energetic solar event reports from the preceding day. See sample
below
A summary of significant solar events including start, maximum,
and end times, region number and location, x-ray and optical
classification of flares and significant radio emission. All
available data for an event are included in this section if one
or more of the following thresholds are reached:
o Class-M or greater x-ray flare,
o Optical flare of importance >2b,
o Radio burst of >100 sfu at 245 MHz,
o Radio burst >100% above background at 2695 MHz,
o Type II or IV sweep frequency burst.
Available:
via SWPC Anonymous FTP server ftp.swpc.noaa.gov.

OLD NOTICES
======================================================================
GOES 14 Became Primary Satellite for XRS data
No Secondary Satellite for X-rays or Electrons and Protons
December 1, 2009: GOES 14 is the Primary SWPC GOES Satellite for X-ray Events.
There is no Secondary X-ray Satellite at this time.
======================================================================
GOES 10 Decommissioning Dec 1, 2009
GOES 14 Becomes Primary Satellite for XRS data
No Secondary Satellite for X-rays or Electrons and Protons
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 Satellite for X-ray Events.
!!!!! Another GOES Satellite Change !!!!!
May 15, 2003 -- GOES 12 is now SEC's primary GOES satellite. Energetic
Events are from GOES 12, but again the change is transparent.
See details at http://www.sec.noaa.gov/GOES.html
========================================================================
!!!!! NOTICE GOES Satellite Changes !!!!!
!!!!! GOES 8 Ended, GOES 12 Begins !!!!!
April 8, 2003 SEC stopped using GOES 8 data.
Energetic Events are from GOES 10, but the change is transparent.
See details at http://www.sec.noaa.gov/GOES.html
========================================================================
June 8, 2001
FORMAT CHANGE
Two Space Weather Event Reports sections were dropped June 8, 2001 --
The Possible_Coronal_Mass_Ejection_Events section is not available
because SEC and the USAF stopped producing the daily Solar
Coronal Disturbance Report.
In addition, the Proton_Events section has been discontinued
until a reliable source for these reports is available.
