An IRIG-B timing error occurred at about 22:15 UTC June 14, 2012 on all of the front end computers at the Y end station. This went unnoticed until this morning. I have corrected the problem by restarting the models on the following computers: h2pemey h2susauxb6 h2tcsey h2pemeyaux Note that the remaining two computers, h2susb6 and h2seib6 were restarted late yesterday afternoon to correct what appeared to be a RFM error, so the IRIG-B time was reset then. Models affected: h2pemey h2iscey h2susauxb6 h2tcsetmy h2pemeyaux and the IOP models for the computers. Work completed at 17:45 UTC June 15.
