A clock discontinuity (reset) of about 675 microseconds was detected for
PRN30 at approximately 10:15 on day 191.

Due to potential problems, data from stations mentioned below 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.)
