January 10, 2011 --  GOES 15 will replace GOES 11 on plots as the 
Secondary SWPC GOES Satellite for Protons, Electrons, and Magnetometer 
in late February. See details at http://www.swpc.noaa.gov/Data/goes.html

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/

The SWPC Warehouse is an FTP directory with historical SWPC Products 
and plots from 1996 up to the current day.

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.

               GOES 15 Designated Primary X-ray Satellite
   
October 28, 2010 --  GOES 15 replaced GOES 14 as the Primary SWPC GOES 
X-ray Satellite. GOES 14 is being moved into storage. There is no 
Secondary SWPC GOES X-ray satellite.

=========================================================================
                        At 0000UT OCTOBER 28 
    GOES 15 Will Replace GOES 14 as Primary Satellite for XRS data
   
October 13, 2010: At 0000 UT October 28 GOES 15 will replace GOES 14 
as the Primary SWPC GOES X-ray Satellite. GOES 14 is being moved into
storage. There is no Secondary SWPC GOES X-ray satellite.

==========================================================================
	          GOES 13 Designated Primary Satellite for 
	           Proton, Electron and Magnetometer Data
		   
April 14, 2010 -- GOES 13 became the Primary SWPC GOES Satellite for the
Proton, Electron and Magnetometer instruments and GOES 11 was designated 
the Secondary Satellite. GOES 12 is being decommissioned.

GOES 13 is drifting to the GOES West longitude. It will be at West 75 by 
April 26, 2010.

Revised Geometrical Factors for GOES 13, 14 and 15 EPEAD Electron Channels

                         On April 14, 2010
	  GOES 13 will be designated Primary GOES Satellite for 
	        Proton, Electron and Magnetometer Data
   
April 6, 2010: On Wednesday, 14 April, the GOES 12 satellite will 
be decommissioned. At that time, GOES 13 will become the Primary
SWPC GOES Satellite for the Proton, Electron, and Magnetometer 
instruments. GOES 11 will become the Secondary Satellite.

Beginning at 0000UT April 14 these Satellite Environment, Electron Flux, 
and Proton Flux plots will show GOES 13 data. The Magnetometer plot
will show GOES 13 and 11 data.

             GOES 14 Primary Satellite for XRS data
   
December 2, 2009: The GOES 10 satellite was decommissioned Dec 1.
GOES 14 is the SWPC Primary SWPC GOES X-ray Satellite. 

3-day X-ray Plots with show GOES 14 data
3-day Electron Plots with show only GOES 11 data


The GOES 10 and GOES 14 XRS instruments have very different electronics and 
therefore, there aree some qualitative changes in the appearance of the 
data. The main difference is 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 are 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 GOES 10.

                 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.

      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.
