F. Comments

  Beginning 1500 UTC April 8, SEC
will begin using data from the GOES 12 satellite,
and stop receiving GOES 8 data. GOES 12 has the
new Solar X-Ray Imager (SXI), which will acquire
real-time, operational images of the solar x-ray
flux. With the switch from GOES 8 to GOES 12, the
primary/secondary designations will change. GOES
12 will be the primary satellite for the SXI.
All other data, including magnetometer, XRS x-ray
measurements, and energetic particles, will have
GOES 10 as their primary source, with GOES 12
as the secondary source where available. Please
see http://www.sec.noaa.gov/GOES.html for important
information on this changeover.
