**COMMENTS/CHANGES:**

NOAA-12 No change from last week although the N12 battery's maximum
discharge voltage continue to slowly trend upward

during the past week in conjunction with the continued waning of eclipse
season (expected to end completely in mid-August). Additional
reconfigurations are anticipated for the N12 power subsystem in the
coming weeks that may include turning HIRS and MSU back on and moving
the solar array offset. Specific operations are not yet defined. Carl
Gliniak is EMOSS POC for this situation.

NOAA-14: No changes since previous report. Power balance remains stable
with no problems detected during the past week.

NOAA-15: The N15 AMSU's, AVHRR and HIRS were all nominal and stable last
week (illustration 1). N15 continues progressing nominally through its
eclipse season (illustration 2) which is now waning and expected to end
late this week or early next week. No power subsystem reconfigurations
are expected.

NOAA-16: The N16 AVHRR scan motor current was stable to slightly higher
during the past week (illustration3) while its synch

delta remained generally pegged most of the time and a large percentage
of its imagery continued to produce bar code noise (illustration 4).
Otherwise N16 payloads were generally nominal and stable during the past
week (Illustration 5) as were the remainder of N16 subsystems.

In order to support the N18 pitch oscillation (TOAR 447) investigation,
at NASA request, EMOSS engineer Carl Gliniak configured the spacecraft
to dwell on the SA Boom movements (NSADPLY) for one orbit on 19 July at
14:45z before configuring the dwell back to Bus Voltage at 17:50z. This
operation completed nominally.

NOAA-17: EMOSS continues closely monitoring the N17 gyro-2 spin motor
current which was generally stable during the past

week (illustration 6). That stability notwithstanding, to bring more
attention to bear on the N17 gyro situation, EMOSS POC Jim Sheperd
submitted TOAR 451 on this component because of its recent
instabilities. Otherwise, there was no change in N17 last week with all
payloads operating in a nominal fashion (illustration 7).

N17 SBUV standard operations will be altered in the near future. One
change will replace the SOMS proc TUESF1DS with SBFLX1DS for Tuesday
SBUV schedules (with relative timing retained). Previously the SBUV was
placed in sweep mode every Tuesday for 14 orbits. The SOMS proc TUESF1DS
was created to replace SBFLX1DS on Tuesdays. It includes commanding to
ensure the SBUV would go to sweep mode when it completed. Now we only
want to keep the SBUV in sweep mode for 4 orbits on Tuesdays, so the
extra commands in TUES1FDS erroneously place us in sweep mode. Jim
Walters is POC

A second N17 SBUV change occurs on the first Saturday of every month
when the SBUV will go into cathode mode for four orbits. These four
orbits are to be chosen such that the daylight portion of the orbit does
not fall on the continental US. The SOMS procedure used to implement
this is SATCATH.PRC. The version of this proc to be used is the 11 July
2005 version. Previously, the earlier version of SATCATH.PRC placed the
SBUV in cathode mode for 14 orbits, and not the desired 4 orbits. Jim
Walters is POC

As with N16, in order to support the N18 pitch oscillation (TOAR 447)
investigation, at NASA request, EMOSS engineer Carl Gliniak configured
the spacecraft to dwell on the SA Boom movements (NSADPLY) for one orbit
on 19 July at 15:30z before configuring the dwell back to Bus Voltage at
18:30z.

NOAA-18: Some OV testing and reconfigurations continue for N18 primarily
those in support of TOAR investigations. On 19

July at 13:30z, EMOSS engineer Jon Woodward oversaw an operation that
Replaces Euler attitude angle errors in the SCP1 CPU telemetry table 1
with that of MIMU raw gyro data. This state will be maintained until 20
July at 19:30z and is being conducted to provide notch filter testing
for pitch angle noise in support of TOAR 447 (excess pitch oscillation).

The final planned OV test concerns that of the SARR which on 18 July at
20:05z had its 121, 243, and 406 receivers switch to fix gain mode (from
AGC mode.) Will Chadwick was EMOSS POC for planning the operation and
Jim Walters oversaw its execution. This configuration is expected to
last 1-2 weeks after which it will be placed back into AGC mode for
nominal operations. There is no illustration for this operation because
of an ABE data gap that occurred just prior to its implementation.

See illustrations 8-12 for a summary of N18 performance over the past
week.
