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. Since the XRS data ceased from GOES 11 and GOES 12, there has been no Secondary SWPC GOES X-ray Satellite. With the decommissioning of GOES 10, there will also be no Secondary Satellite for Electrons and Protons. There should be only minor differences in the appearance of the XRS data and only at the lowest flux levels.
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-7 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-7, the noise will decrease and the plots will look very similar to the GOES 10 data.

3-day Solar-Geophysical Forecast issued Nov 20 22:00 UTC
Solar Activity Forecast: Solar activity is expected to be at very low levels with a slight chance for a C-class flare.
Geophysical Activity Forecast: The geomagnetic field is expected to be unsettled with a slight chance for an active period on day one (21 November) due to a recurrent coronal hole high-speed stream. Conditions are expected to be predominantly at quiet levels for day two and three (22-23 November).

Although these data are of interest to the satellite community, they do not include all parameters and energy ranges known to be associated with satellite anomalies.
