This week we include the following information:

Polar motion results for 12 to 18 Sept.

    The set of coordinates described below is based on the 
    analysis of the first 51 days of the IGS campaign, and
    include coordinates of the PGGA sites after the Landers earthquake.

1. Analysis Center: Scripps Institute of Oceanography
2. Solution Identifier: Submission 920924
3. Software used: GAMIT/GLOBK
4. Definition of Terrestrial Reference Frame:
     Origin: Nominally ITRF-90
     Orientation: Nominally ITRF-90
     Reference epoch: 1992.57  (MJD 48829.5)
     Relativity Scale: Terrestrial
     Velocity of light: 299792458.0 m/sec
     Permanent tidal correction: None

5. Adjusted parameters:
   (a) Double-difference data
   (b) Single day orbit arcs, 6 ICs and 3 radiation parameters per 
satellite-per-day
   (c) One-per-day-per-station zenith tropospheric parameter,
   (d) Bias parameters, one for each independent double difference 
combination.
   (e) Station positions with +- 10 m constraints at stations other 
than: ALGO, YELL, PIN1, PINB, JPL1, JPLB, SIO1, SIO2, FAIR, KOKR, 
USUD, DS10, DS1B, DS40, DS41, DS60, YAR1, MCMU, TAIW, ONSA, WTZ1, 
METS, MATE, TROM, NALL, KOSG.  For these stations constraints of
+0.001 m for horiziontal and +-0.005 m for the height were used.
   (f) X and Y pole position once per day.  (No estimate is made of UT1-
AT since these deviations are absorbed into the orbital parameters).
   (g) On MJD 48800.5, the California sites are treated as separate
sites before and after the Landers earthquake.

6. Station coordinates used.

NOTES:
 (a) The epoch refers to the epoch at which the site position applies
and not the mid-point of the data span.  We have also added the
velocities adopted for these sites at the end of each line.  For most sites
these are the NUVEL-1 velocities with the North American AM0-2 velocity
added.  For PIN1 and DS10, Observed velocities (based on a combined VLBI/
GPS solution using ~10 years of data have been used).
 (b) The PEQ notation in the site name (PINB, DS1B, SIOC and JPLB) denotes 
post-Landers earthquake position (applicable after 11:58 UTC June 28, 1992).
 (c) These coordinates were estimated from the first 51 days of IGS data.
They have been rotated and translated into the ITRF 1990 frame by use
of the horizontal coordinates at all sites.  The rms difference between 
the horizontal coordinates of these sites and our previous realization 
(second IERS submission) was 5 mm.

NOTES: UT1 not estimated.  Value given is apriori used in analysis.  The rms is the square root of chi**2
per degree of freedom in our solution.  It nominally should be 1.0.  st and sv are numbers of stations
