We have excluded data from this satellite on this day and the following day (021) as well. We have refined our estimate of JPL's position following the Northridge Earthquake of 12:31 UT on January 17. Using the receiver at Goldstone as a reference (expected motion of Goldstone following this event is much less than 1 mm; the removal of this station as a fixed site, in retrospect, is not necessary), and data from Jan 12 through Jan 22, we estimate motion as follows: north -5.7 +- 1.4 mm east 7.4 +- 1.0 mm vertical -2.6 +- 3.5 mm These values are consistent with our earlier result (IGS mail 455) and those from SIO (Bock et al., IGS mail 457). WARNING: Because of the Northridge Earthquake (day 017), GOLD was not used as a fiducial (constrained) site for the entire GPS week 732. WARNING: Due to the maneuver of PRN17/GPS17, data from this satellite have been deleted for days 020 and 021.
