F. Commentaren

  K-Indices:
On 16 June, it was determined that a scaling problem exists with the
H-trace on 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.
Beginning 1700 UTC on June 18, GOES 11 (105W) will become 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.
