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
On 16 June, it was determined that a scaling problem exists with the Boulder magnetometer instrument.  While this problem, and its fix are being investigated the primary instrument for Boulder K-indices has been switched to the Boulder USGS (via Domsat) magnetometer, effective 1500 UTC on 16 June.
GOES Protons:
To ensure continued operational monitoring of important energetic particle data, it is necessary to reassign primary/secondary designations for the GOES Space Environment Monitor (SEM) detectors. GOES 11 (113W) is now the primary satellite for protons. GOES 12 will continue as the primary satellite for magnetometer, X-ray, and electron measurements. GOES 10 (135W) will be the secondary satellite for all SEM sensors - magnetometer, X-ray, and energetic particles.  Because of the degraded state of the proton data on GOES-10, its designation as the secondary source for proton data is a short-term solution.  More permanent solutions have been identified and are being evaluated.  Users will be notified when we define and schedule a permanent fix. The missing (Msg) daily fluence data and the X-ray background data will be corrected on 23 June. Further details can be found at http://www.sec.noaa.gov/GOES.html.
