**COMMENTS/CHANGES:**

NOAA-12: Eclipse season is progressing nominally and there has been no
repetition of the autonomous SADBIAS implementation

that occurred on 29 Apr. On 10 May at 20:10z the SADBIAS value was
commanded back to 80 deg offset (where it should be, vs. 54 deg where it
actually was) after which SADBIAS was re-enabled for the first time
since the 29 Apr event.

NOAA-14: N14, batteries continue to trend lower (illustration 1) during
the dark part of their orbit, again falling slightly below 20

volts, despite Engineers turned off the nominal and operational SSU
payload on 5 May, in order to conserve power and prevent a potential
power survival safestate situation.

The N14 SARR continued to operate at or near all time high temperatures
during the past week (illustration 2). There is presently no health
related concerns that have been identified

NOAA-15: The N15 AMSU's A1 and A2 were generally nominal during the last
week while continuing their thermal uptrends.

On the other hand AMSU-B continued to exhibit slightly less stable scan
motor current performance (and trends) during the past week although it
remains within historically acceptable norms (illustration 3). The N15
AVHRR also showed slightly less than optimum scan motor stability during
the past week although it too remains within historically acceptable
norms (illustration 4). There have been no reports received of degraded
products from either of these situations.

N15 began its eclipse season on 15 May as the first battery discharge
currents were registered. At the present time no reconfigurations are
planned and the eclipse is proceeding as predicted (illustrations 5 and
6).

The N15 Attitude Control Subsystem was also generally nominal and stable
last week (illustrations 7 and 8).

NOAA-16: The N16 payload suite was also generally nominal and stable
during the past week (illustration 9) with the

AVHRR sustaining its historical low scan motor current and all other
performing in a nominal and stable manner. Thermally N16 remains stable
with no discernable trend. The N16 ADACS subsystem was also nominal
during the past week (illustrations 10 and 11) relative to its severely
degraded status although there were some minor perturbations on 13 and
14 May due to a full moon and sun-moon warning events.

NOAA-17: The N17 AVHRR scan motor continues to exhibit less stability
than engineers prefer but also continues to produce nominal products.
The scan motor current "mini surges" continue to increase in frequency
but the value remains within an acceptable norm. Changes to the synch
delta value generally mirrors the scan motor current changes Engineers
continues to monitor this payload closely. In addition, the N17 HIRS
showed slightly less stability on the past several days as the filter
motor current increased slight and the period monitor value range
followed suit. Otherwise the N17 payload suite was nominal during the
past week (illustration 12).

NOAA-18: Most of the N18 payload suite was nominal and stable during the
past week (illustration 15) except for the HIRS which

started to degrade on 8 May and has remained that way since that time.
Furthermore, for the first time, the filter housing temperatures
appeared to show slightly less stability by suddenly rising slightly in
conjunctions with a slight rise in filter motor current (illustration
16). HIRS imagery remains degraded in numerous channels at the present
time (illustration 17). The payload remains Yellow in status with no new
tests or reconfigurations under consideration at this time

The N18 ADACS was nominal during the past week (illustrations 18 and 19)
and the TCE3H heater continued its abnormal telemetry reporting which
resulted in TOAR 458 being submitted two weeks previous. Ultimately,
there were no changes to N18 during the past week.

(AMSU-A1 and A2 were both nominal and stable last week although their
thermal uptrend's continued. AMSU-B continued to run at slightly higher
than usual scan motor currents. Note the jump in AMSU-B motor current
coinciding with that of its component temps on JDAY 130 \[10 May, red
x.\])
