______________________________________________________________________________

Beginning this week, we include data from a new site: ZWEN (Zwenigorod, 
Russia).  As with most stations, this site is given the opportunity to 
participate in the orbit and clock solution as the global site distribution 
varies.  The following nominal coordinates were assumed:

   ZWEN: X =  2886326.9031 m,   Y =  2156014.5359 m,   Z =  5245950.1960 m

Due to potential problems, data from the following stations were not
considered for use in the global solution for the day indicated.  (For
geographical reasons, they may not have been used in any case.)

WARNING: Data from LAMA excluded on day 099 (Apr 9).
WARNING: Data from MATE excluded on days 100 and 101 (Apr 10,11).
WARNING: Data from CASA, DRAO, MATE excluded on day 102 (Apr 12).
WARNING: Data from CASA, CICE excluded on days 103 and 104 (Apr 13,14).
WARNING: Data from CASA, MDO1 excluded on day 105 (Apr 15).

In the following table, UT1R-UTC are the integrated values based on estimated
LODR values in the adjacent column.  See IGS Report No. 1498 (jpl07827.sum)
