**COMMENTS/CHANGES:**

NOAA-12: There were no changes to N12 during the past reporting period.

NOAA-14: With the exception of a single quick surge on Christmas Day,
the N14 AVHRR scan motor has remained nominal

during the past week (it was recently upgraded in status to YELLOW) as
has the N14 Power subsystem (illustration 1).

No further planning was conducted on the N14 MSU "tilt test" during the
past week.

NOAA-15: The N15 payload suite was nominal last week with the AMSU's
starting a thermal downtrend and AMSU-B showing

some minor scan motor current instabilities. In addition, the AVHRR
continued to show continued slow and minor improvements in scan motor
current values, retreating from some recent "multi year" high values
while the HIRS remained solidly nominal (illustration 2). Finally, the
N15 ADACS subsystem was also nominal and stable during the past week
(illustration 3).

NOAA-16: The N16 AVHRR scan motor current fell to its lowest values ever
during the past week but then began to exhibit some

instabilities albeit within nominal values while the HIRS filter motor
current continued to operate at or near all time high values and
high-low ranges (illustration 4). The N16 ADACS also remained "nominal"
relative to the constraints of it now very limited capability
(illustration 5).

NOAA-17: The operational N17 AMSU's were stable and nominal during the
past week while the N17 AVHRR was nominal but

slightly less stable, displaying an operating range very similar to that
exhibited by the N16 AVHRR last week (minor "surges" well within nominal
values (illustration 6). The N17 ADACS was also nominal and stable
during the past week with no new "perturbations" to report
(illustrations 7 & 8 ) and the auto gas unloading threshold for pitch
momentum remained at \<-40 or \>+40 ft lbs (somewhat close to its
current value which is averaging around +38).

NOAA-18: The N18 HIRS period monitor appeared to "tighten" during the
past day with no other components showing any out of

family operational changes (illustration 9) Meanwhile, MHS experienced
no further perturbations either during the past week (illustration 10)
and the EMOSS team submitted a new TOAR (456) because of the 16 Dec
problem (see last weeks report). Otherwise N18 was nominal during the
past week (illustration 11 depicts ADACS performance values).

.

Plans are currently being generated that will change the APT data stream
on N18 to VTX-1 (137.10 MHz). This is scheduled to take place on 4 Jan.

MISC: On 1 Jan all POES spacecraft will experience a "leap second" that
will increase their command clock by 1000 mSecs (1 full

second). To compensate for this change as well as drift that has
occurred through the year, EMOSS will be changing all spacecraft command
clocks EXCEPT N12 on 31 Dec at 23:59z. Of the spacecraft that will have
a clock update all of them except N15 will have 1500 mSecs (1.5 seconds)
subtracted. For N15 only 500 MSecs (0.5 sec) will be subtracted. For
more information on this operation see the clock matrix (illustration
22) at the end of this report.
