                 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 X-ray Satellite. 

3-day X-ray Plots with show GOES 14 data beginning Dec 1, 2009
3-day Electron Plots with show only GOES 11 data beginning Dec 1, 2009


                 Changes to the GOES XRS Data
The GOES 10 and GOES 14 XRS instruments have very different electronics and 
therefore, there will be some qualitative changes in the appearance of the 
data. The main difference will be the level of noise in the data at the
lowest values. When the background levels are low (less than 2E-8 W/m2 or
A2.0), the GOES 10 data looks flat and the steps are very abrupt. At these 
low flux levels, the GOES 14 data will be quite noisy.  As the x-ray flux 
levels rise up above 2E-8, the noise will decrease and the plots will look 
very similar to the  GOES 10 data.

      GOES 11 Becomes Primary Electron Satellite, GOES 10 Secondary

December 1, 2008 -- On Friday, 28 November, the GOES 12 Electron sensor 
began experiencing periods of noisy data. On December 1 SWPC changed its
GOES Electron satellite designation to make GOES 11 the primary GOES 
Electron satellite and GOES 10 the secondary.

Beginning December 1, the 3-day GOES Electron Flux Plots show GOES 11 
and GOES 10 data.

This directory has 3-day plots of Space Weather data in GIF format. 
The current day's plots are updated every 5 minutes. Plot files for
the last 60 days are on the SWPC Anonymous FTP server and accessible
via the Web.
    Via Anonymous FTP: ftp.swpc.noaa.gov cd to /pub/plots/ 
    Via the Web:       http://www.swpc.noaa.gov/ftpmenu/plots.html

The SWPC Warehouse is an FTP directory with historical SWPC Products 
and plots from 1996 up to the current day. 
     Via Anonymous FTP: ftp.swpc.noaa.gov cd to /pub/warehouse/
     Via the Web:       http://www.swpc.noaa.gov/ftpdir/warehouse/


Plots are in sub-directories named by data type.
     xray	    GOES X-ray Flux Data (5-min data)
     electron	    GOES Energetic Electron Flux (5-min data)
     proton	    GOES Integral Proton Flux (5-min data)
     goeshp	    GOES Magnetometer, H-component (1-min data)
     kp		    Estimated Planetary K-indices (5-min data)
     satenv         Satellite Environment (GOES Protons, Electrons, 
                     HP, and est. Kp)

Plot files are named with the year, month, day of the last day
on the plot and the data type. For example, 20060206_xray.gif  
is the X-ray plot for February 4-6, 2006.

Static filenames for the latest plots and updating web pages are 
described at:  http://www.swpc.noaa.gov/rt_plots/
     
The "support" directory contains short ascii text files with to
current West longitude of each GOES satellite, updated daily.
