**COMMENTS/CHANGES:**

NOAA-12: EMOSS engineer Carl Gliniak is investigating some recent bus
voltage instabilities on N12. Nothing is yet considered

anomalous but some change in performance was detected in recent days and
possible reconfigurations may be necessary to compensate for these
changes (illustration 1). Presently, a turnon of the MSU is being
considered the best way to approach this situation with approval from
NOAA management still pending the date for such an operation is TBD.

NOAA-14: N14 was commanded back to nominal mode on 30 Nov at 18:35z with
yaw precision improving markedly as a result.

However, almost exactly 24 hours later, as STX-1 was being turned on,
the spacecraft again autonomously switched into YGC mode (where it
remains today) with yet another degradation of yaw precision resulting.
At the time the switch occurred the NESAAI1 value was being dwelled upon
(1 second dwell) so additional data is now available for the continuing
investigation into this phenomenon. With the main SOCC operational
equipment move currently underway, and no complaints from direct readout
users being received by NOAA, it was determined that N14 will remain in
YGC mode at least for the next couple of weeks. Jim Shepherd is leading
the EMOSS side of this investigation. Plans are still in effect to place
the ESA in high speed dwell mode for 10 seconds before and 10 seconds
after a STX-1 turnon (out of the ground schedule) but the date for this
operation is presently TBD.

Other than the YGC mode operations the remainder of the N14 spacecraft
performed nominally during the past week with the power subsystem
remaining nominal and the AVHRR experiencing no scan motor current
spikes during this entire time period (illustration 2).

NOAA-15: There were relatively no changes to the N15 health situation
during the past week. Illustrations 3 and 4 depicts primary payloads and
ADACS component performance during this time frame.

NOAA-16: There were relatively no changes to the N16 health situation
during the past week (except a minor improvement in the

AVHRR scan motor current and a reversal of the AVHRR thermal uptrend,
Illustration 5). In general, N16 attitude control was nominal during the
past week (illustration 6) although there was a short lived surge in the
gyro-2 spin motor current on 2 Dec which was accompanied by a change in
IMU block temp and TCA voltage (illustration 7). Given the significant
degradation of the N16 ADACS even small performance changes are a matter
of concern. Fortunately, these values quickly returned back to their
more typical performance ranges.

Starting mid-September 2007, N16 will transition from what had always
been a permanently eclipsing spacecraft to a full sun orbit (with
eclipse seasons each summer). This orbit-sun profile has been predicted
to last at least until 2011 but may last even longer. Carl Gliniak is
investigating the implications of this change in order to be proactive
about any reconfigurations that might be required when this even begins
(see illustrations 17a and B at the end of this report).

NOAA-17: The N17 payloads generally performed nominally during the past
week (illustrations 8) and no new concerns or

information has been forthcoming regarding a possible problem with the
N17 SBUV (see last weeks report). Otherwise, the N17 ADACS was generally
nominal and stable during the past week although the IMU TCA voltage did
experience a short lived surge on 29 Nov that was not accompanied by any
other changes in ADACS component performance characteristics
(illustrations 9 and 10) except perhaps a one count increase in gyro-1
spin motor current. Such surges in TCA voltage may be indicative of a
problem within the gyro and concerns with KLM gyro performance are
continual. However, everything returned back to nominal values and
ranges within a short period of time so at the moment there does not
seem to be cause for concern.

NOAA-18: The N18 HIRS remained nominal from an engineering standpoint
but degraded from a long wave imagery user perspective during the past
week (illustration 11). On the other hand, the N18 AVHRR and AMSU's
performed nominally and stably during this same time period
(illustration 12). The MHS was also relatively nominal during the past
week except that the flywheel motor abruptly showed an increase of more
than 100 mAmps (illustration 13) starting on 29 Nov (within previously
observed norms). Analysis of this payload has been difficult in the past
week because of the excessive number of noise spikes introduced by the
ABE trending system into the engineering data stream.

Otherwise the N18 ADACS performed nominally during the past week
(illustration 14 and 15) while the momentum transition (from negative to
positive values) addressed in previous Weekly Reports appears to have
reached its new equilibrium (illustration 16). Since 29 Nov, the torquer
coils have again begun to activate to unload the Rwheels and preliminary
analysis has determined that they are all performing nominally.

(Perhaps the worst noise interjection by ABE since N18 launch
significantly reduces the fidelity of these two plots. However, on Jday
333 \[again 333\] it is noticeable that there was an abrupt increase in
the flywheel motor current although the range remains within acceptable
norms.)
