Geophysical report

Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

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.
