K-Indices:
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.  Further details can be found at http://www.sec.noaa.gov/GOES.html.
