HH determined that the OST file was incomplete. FH was called, and after some investigation, it was determined that he would come in and fix the problem himself. The OST file contains nothing past obset y2lt56, the last obset on day 166. However, the final 28 or so observations in the OST are a repeat of all the day 166 observations UP TO y2lt5601. FH will be coming in to fix the problem.
T remains in trouble in the pipeline pending further investigation.
There was no DA scheduled, so no data assessment was done.
