**COMMENTS/CHANGES:**

NOAA-12 Because of an RF conflict with N16, N12 continues to have far
fewer passes resulting in less capability for ensuring

nominal health of the spacecraft. With the data currently available
there does not seem to be any problems at this time.

EMOSS engineers will be monitoring spacecraft response to a solar
eclipse event that will occur for 10-15 minutes per orbit on three
successive orbits between 00:30 and 04:30. No reconfigurations are
planned for N12 based upon predicted response by the EMOSS solar eclipse
model. EMOSS POC for this situation is Carl Gliniak.

NOAA-14: The N14 power situation remained stable during the past
reporting period with minimum battery voltages remaining above 20.5 most
of the time. Recently, the percentage of time that N14 spends in the
dark during each orbit has begun to slowly increase. This trend is
expected to continue through mid-November where the darkness percentage
should peak at 23% per orbit. By that time, it may be possible that a
power subsystem reconfiguration will be required to maintain an adequate
margin and ensure no undervoltage situation or additional shunt stress
occurs. Discussions and analysis are ongoing.

eclipse event that will occur for 10-15 minutes per orbit on three
successive orbits between 00:30 and 04:30. No reconfigurations are
planned for N14 based upon predicted response by the EMOSS solar eclipse
model. EMOSS POC for this situation is Carl Gliniak.

NOAA-15: The cooling trend on N15 appears to have bottomed out last week
in conjunction with the sun angle reaching its bottom of 8 degrees
(illustration 1). Currently there appear to be no subsystem health or
image quality associated with the low temperatures achieved during this
cooling trend.

During the past reporting period, the N15 experienced a small scan motor
current surge on 12 Oct that appeared to return to nominal after several
hours. There were no reports of image degradation from this event and
none were apparent in EMOSS analysis or HRPT data. In addition, the HIRS
filter wheel continued its standard "mini surge" behavior as it has done
for many months without any reported imagery degradation. In contrast,
the AMSU-B did not experience any scan motor current surges last week
(illustration 2).

model. EMOSS POC for this situation is Carl Gliniak.

NOAA-16: The N16 AVHRR scan motor current, had a small surge on 8 Oct
that appears to be slowly returning to nominal. In conjunction with this
small surge, the synch delta value actually fell to near zero where it
has remained since that time This type of response from synch delta is
actually the opposite of what usually transpires. Furthermore, the small
current surge was in no way accompanied by a rise in scan motor
temperature which is on an upward trend at this time, a trend which is
aided by TCE24 remaining turned off. There did not appear to be any
impact on N16 AVHRR imagery from this current surge nor was nay reported
to EMOSS. Sally House and Jim Walters are EMOSS POC's for this payload.
(See illustrations 3-6).

The N16 HIRS was also stable and nominal during the past reporting
period and showed no impact or thermal coupling with AVHRR during the
AVHRR mini surge (illustration 7). No additional information regarding
the noisy channels reported last week has been received by EMOSS
engineers. Finally, the HIRS Patch power, which is currently on the
EMOSS "watch list" was stable throughout the past reporting period.

The ADACS on N16, as measured by its gyro motor currents and yaw update
values was also nominal during the past reporting period (illustration
8). However, the performance profile of the N16 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
(illustrations 9-10). This issue started on or about 30 Sept and current
opinion is that it does not constitute a health issue for the ADACS at
this time. In response EMOSS engineer Jim Sheperd submitted an Event
Report on this issue.

An SBUV test characterizing the SBUV's wavelength dependence of the
inter-range ratio between range2 and range 3 measurements continues
executing out of stored commands in Flex Memory-3 (illustration 11).
This series of tests is expected to end this week after which
implementation of a follow on test will be considered. Jim Walters and
Sally House and EMOSS POC's for both of these tests.

EMOSS engineers will be monitoring spacecraft response to a solar
eclipse event that will occur for 10-15 minutes per orbit on three
successive orbits between 00:30 and 04:30. The SADPOS software on N16
will be disabled prior to the eclipse because the EMOSS solar eclipse
model predicted that the spacecraft would be less than 40% illuminated
for approximately 7 minutes during on phase of this event. This value is
very close to the 8 minutes at \<40% illumination that is the threshold
for SADPOS autonomously taking control of the solar array. To ensure an
added degree of margin, EMOSS engineer Carl Gliniak will turnoff SADPOS
software while the eclipse is ongoing and then turn it back on after the
event is concluded.

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

the past week, the performance remained stable at the higher values
first observed several weeks ago while its synch delta value operating
profile also stabilized within the slightly more "erratic" range that it
recently established. In addition, N17 AVHRR temperatures continue to
operate in nominal range and values and there have been no reports or
observations of degraded imagery (illustration 12). Sally House and Jim
Walters are EMOSS POC's.

The ADACS on N17 was also nominal during the past reporting period
although slightly less stable (as measured by gyro currents) than that
on N16 and much more stable in comparing with N16 ESA (illustration 13)
Jim Sheperd is EMOSS POC.

EMOSS engineers will be monitoring spacecraft response to a solar
eclipse event that will occur for 10-15 minutes per orbit on three
successive orbits between 00:30 and 04:30. No reconfigurations are
planned for N17 based upon predicted response by the EMOSS solar eclipse
model. EMOSS POC for this situation is Carl Gliniak.

NOAA-N: EMOSS engineers began regenerating the ascent data base
originally delivered in mid-June 2004. This data base is

scheduled to be re-transmitted to NASA on 22 Oct and into PACS by 2 Nov.
Michelle Settles is EMOSS POC.

EMOSS engineers continue supporting reviews, analysis, testing and
product preparations for the 20 Oct end to end tes.

MISC: EMOSS power engineer Carl Glinak wrote an SER on the preparations
for the solar eclipse on 14 Oct as well as

presented a chalk talk to each crew regarding the important operational
features for this event.

Meetings supported by EMOSS included: Internal launch readiness meeting,
MOWG, Ascent data base recovery meeting, COP Reviews, N18 Monitoring
Guidelines Training and COP reviews.

The next database release is scheduled for Nov. 2.  All approved CCRs
should be turned into Michelle no later than Oct. 25.

EMOSS engineer Jim Sheperd supported the scheduling office on the SOMS
generated ephemeris loads which was used operationally for first time
this past week.

EMOSS engineer Jeff Devine worked with the software office to develop
and test a process that will ensure the EMOSS HAF file archive can be
reformatted in DMF file that are required by ABE. The reformatting
process was successful but ABE was still unable to generate graphs from
the file. Work is continuing.
