	Pass Summary:
	A non-nominal pass in many respects, yet there was no impact to
Realtime operations.  SSR redumps were not completed but all other nominal
daily commanding was performed successfully before the scheduled EOT.
	The Spacecraft switched from 498 to the high data rate at Beginning
of Activities at 162500 due to operator error.  NOAA and Air Force were
both notified of this change.
	Command capability was transferred from the prime string to the MAR
test string.  One no_op command was sent to each C&DH (Active & Inactive)
using the MAR string.   Command was given back to the prime string
following their successful verification.
	AOS was delayed by ~20 minutes due to D27 having bad predicts.  The
INIF protoserver was also down for approximately 25 minutes.  SSR Redumps
to be completed during next pass.

	Anomalies:
	G99-0030 - DR# G04794 - Delayed AOS due to bad predicts at DSN site.

	Pass Summary:
	This support was initially setup as an ISIS Y2K s/w checkout using
r/t spacecraft data.  Due to late schedule changes, the information for
compiling the briefing message was not available and no briefing message
was sent.
	Late in the day before the test, it became apparent that all
parties were not ready to support the test and so the TEST was cancelled.
The DSN support was NOT cancelled & nominal s/c activities were planned
using the non-Y2K INIF.
	The time tag bin had been loaded during the previous days pass (and
prior to the test being cancelled) to transition the data to the high rate
at the beginning of this pass.
	ACE MOC did not receive telemetry until ~1300 due to incorrect ISIS
Fanout configuration.  The network had been partially configured for the
test (with the Y2K s/w), with the remaining portions configured for use
with the non-Y2K s/w.
	The two versions of INIF [Y2K and non-Y2K] are not compatible.
Once the network was completely configured by IPNOC and NASCOM for use with
the non-Y2K s/w, ACE MOC received telemetry.
	No commanding to the Spacecraft was performed.

	Anomalies:
	G99-0031   Late AOS due to ISIS misconfiguration by NASCOM

	Pass Summary:
	Due to INIF s/w problems incurred during the day's earlier support
with D66, the AOS time tag bin was not uplinked for this support.  As a
result, the s/c was acquired at the 498 RTSW data rate.
	The remainder of the pass was nominal.
