According to the file nanu1994.mes obtained from the IGS CBIS, PRN20 was
unusable from day 00:00 UT on day 218 (Aug 6) to 19:08 UT on day 229 (Aug 17).
We believe this is manifested in the atypical orbit repeatabilities for
this satellite at the beginning of the week.  No broadcast ephemerides were
available for PRN20 on day 219 (Aug 7), hence the blank space for this
satellite in the Broadcast Orbit comparison table on this day.

WARNING: Data from KOSG excluded days 219 and 220 (Aug 7, 8).
WARNING: Data from HARV exlcuded days 221 and 222 (Aug 9, 10).
WARNING: Data from RCM5 exlcuded days 222 and 223 (Aug 10, 11).
WARNING: Data from HOB2 and MATE excluded day  224 (Aug 12).

In the following table, UT1R-UTC are the assumed nominal values from IERS
Bulletin-B predicts; estimated LODR values are also included.  See IGS Mail
Message 97 for details.
