The motion of PRN11/GPS08 continues to be poorly modeled, and we continue to
deweight its data in our solutions. Data from the recently-launched PRN29/GPS29
began appearing on Dec 31. We will begin including results from this satellite 
in next week's submission.

WARNING: PRN11/GPS08 is poorly modeled at the meter-level for GPSWK 677.
