**COMMENTS/CHANGES:**

NOAA-12 No changes since the last report that can be discerned from the
relatively few passes that N12 has currently been able to

provide.

NOAA-14: The N14 power situation remained stable during the past
reporting period with minimum battery voltages apparently "bottoming
out" since the previous report (illustration 1). The primary driver
regarding the N14 power balance is maximum eclipse duration which has
now about reached its maximum of 23% of each orbit. Presently, EMOSS
engineers believe that this situation is both manageable and beneficial
to the N14 shunts and so, while close monitoring will continue no
reconfigurations have been recommended. Carl Gliniak is EMOSS POC.

EMOSS engineer Jim Walters oversaw the implementation of an operation
that will restore Diffuser Reflectivity Measurements to the NOAA-14 SBUV
Schedule after this operation was inadvertently removed last year during
the grating motor anomaly. This operation will again run out of stored
commands once per week 5 minutes after a terminator crossing into
darkness, and run in the dark part of the orbit taking 35 minutes to
complete. It is expected that this operation will be conducted on
Thursday in conjunction with other N14 SBUV calibration operations
although it can be performed on any day of the week. The first
implementation of this "new" standard operation is planned for Thursday
18 Nov.

NOAA-15: The N15 AVHRR and AMSU-B scan motor current were nominal during
the past reporting period while the HIRS experienced its usual "mini"
filter motor current surges (illustration 2 and 3).

NOAA-16: The N16 AVHRR scan motor continued to behave erratically during
the past week with motor current values averaging 265 mAmps and
approaching the 280 value where bar codes are usually observed on
imagery. Conversely, bar codes have not yet been observed on the imagery
(although wave patterns have been reported) and, for the first time in
nearly two weeks, the synch delta value has stopped "pegging out" on
each orbit. (The non-pegged synch delta has the added benefit of not
requiring an actual rephase of the MIRP on each orbit thus reducing lost
data on other payloads.) Thermally, AVHRR components are at their
highest temperatures ever although the baseplate and scan motor remain
well below the 28.5 degrees which would require EMOSS to command TCE24
back on to allow component cooling (illustrations 4-7). Conversely, the
N16 HIRS was very stable during the past week operating at its lowest
average filter motor current ever and maintaining its thermal stability
as well (illustration 8).

The N16 ADACS was nominal during the past reporting period. The Earth
Sensors continues to exhibit behavior suggestive of direct sunlight
entering the detectors (as depicted by the ESA ORS voltages and Sun Moon
warning status). EMOSS engineer Jim Sheperd continues to closely monitor
the situation (illustration 9).

NOAA-17: EMOSS engineers continue to closely monitor the N17 AVHRR scan
motor for signs of degraded performance. The

scan motor current on this payload continues to edge slowly higher,
beyond that which can be attributed to TIP analog drift, and is now
reaching all time high values. Conversely, imagery and synch delta
remain nominal (illustration 10-11).

The ADACS on N17 was also nominal during the past reporting period
although slightly less stable (as measured by N16) than is desirable
(illustration 12). Jim Sheperd is EMOSS POC for this issue.

NOAA-N: Re-testing of end to end test problem areas (SCT and ephemeris
loads) are scheduled for tomorrow, 10 Nov. The

N18 Comm. Panel is expected to be opened following the completion of
SEPET testing to examine the S-Band transmitter that demonstrated less
than optimum performance during testing. This examination is expected to
result in a launch delay of up to several weeks if it is performed.
EMOSS engineer Jon Woodward updated the latest flight timetable (using
the FT Tool) with MHS/MIU commands as well as several other alterations
and submitted it to NASA for their review.

MISC: EMOSS engineers are currently supporting an anomaly investigation
that is occurring at Fairbanks CDA. Since 8 Nov,

neither the SOCC or Fairbanks (in normal mode) have been able to load
large block files (i.e. Stored Command Table) into any spacecraft at the
Fairbanks CDA. Single commands and simple loads (such as ephemeris) have
been successfully loaded at Fairbanks since this problem started and
large loads to POES spacecraft have been successful at Wallops (and all
such loads have been moved to Wallops until this situation has been
resolved). At the present time, spacecraft hardware has been discounted
as a source of the problem and the current focus is on possible problems
with the S-band command generator (VHS transmitted command loads do work
at Fairbanks) or the Comm Controllers.

On 4 Nov, EMOSS engineer Jon Woodward reset all KLM (N15, 16 and 17)
STESM tables to ensure that only Gyro 1 and 2 for these spacecraft are
powered on and gyro-3 remains powered off (which the previous STESM
would have turned on if implemented). These operations all completed
nominally.

EMOSS engineers have initiated page comparisons for a new CWS software
release. Account difficulties and system problems have resulted in
delays for completing this process. Currently, COB Friday, 12 Nov is the
deadline for completion, assuming everything works nominally.
