**COMMENTS/CHANGES:**

NOAA-12 No change from last week although the N12 battery's maximum
discharge voltage continue to slowly trend upward

(now above 20 volts) during the past week in conjunction with the
continued waning of eclipse season (expected to end completely in
mid-August). Additional reconfigurations are anticipated for the N12
power subsystem in the coming weeks that may include turning HIRS and
MSU back on and moving the solar array offset. Because of the waning
eclipse season some battery Day-Night history flags are starting to show
up which will become non applicable as soon as eclipse season ends.
Specific operations are not yet defined. Carl Gliniak is EMOSS POC for
this situation.

NOAA-14: On 16 July at 14:30z, the N14 AVHRR apparently fixed itself. 
The scan motor current abruptly dropped to nominal as

did its component temperature and synch delta values (illustrations 1,
2, 3). AVHRR HRPT Imagery also returned to nominal (illustration 4). The
payload has remained nominal ever since and, on 21 July, its status was
upgraded to YELLOW (from RED). In response to this event, EMOSS is
coordinating with Scheduling to turn N14 APT data (VTX-2) back on for
the first time in over 3 years (without conflicting with N17 APT data)
on 28 July at 14:00z for 4 days after which it will enter into RF
conflict with N17 and be turned off again. EMOSS engineer Sally House
discovered the AVHRR improvement and Will Chadwick is EMOSS POC for the
APT turnon operation.

The change in N14 AVHRR did not impact the spacecraft power balance to
any discernable degree. Power balance remains stable with no problems
detected since the previous support (illustration 5).

EMOSS engineers received reports from the Products (Ozone) division that
N14 SBUV had stopped producing any data on 25 July. EMOSS investigation
into this already seriously degraded showed no temperature or current
surges being observed and the grating position changing nominally
(although it was changing much more frequently on the day in question,
illustration 6). Products was eventually able to make products from some
of their ingests but their grating monitoring program indicated some
unusual grating errors and some of the data was flagged in sweep mode
EMOSS engineer Sally House is investigating.

NOAA-15: The N15 AMSU's, AVHRR and HIRS were all nominal and stable last
week (illustration 7). N15 continues progressing nominally through its
eclipse season (illustration 8) which is now waning and expected to end
late this week or early next week. No power subsystem reconfigurations
are expected.

NOAA-16: The N16 AVHRR scan motor current was stable to slightly higher
during the past week (illustration 9) while its synch

delta remained generally pegged most of the time and a large percentage
of its imagery continued to produce bar code noise (illustration 10).
Otherwise N16 payloads were generally nominal and stable during the past
week (Illustration 11) as were the remainder of N16 subsystems.

NOAA-17: The N17 payload suite were also nominal and stable during the
past week (illustration 12). Meanwhile, EMOSS

continues closely monitoring the N17 gyro-2 spin motor current which was
also stable during the past week

(illustration 13). One less than nominal situation which did occur on
N17 during the past week was an inordinate number of single event upsets
on CPU2 that had to be scrubbed on 24 July (illustration 14). However,
by mid-day this situation ceased and returned back to normal.

NOAA-18: Some OV testing and reconfigurations continue for N18 primarily
those in support of TOAR investigations. On 25

July at 17:15z, EMOSS engineers Jim Walters oversaw an operation that
parked the AMSU-A1 at a warm target for one orbit and then back to full
scan mode. This operation was repeated on 26 July at 15:35 using both
the AMSU-A1 and AMSU-A2 payloads. These tests were requested by NASA in
support of the HIRS long wave noise (TOAR 448) investigation.

In support of the pitch oscillation investigation (TOAR 447), EMOSS
engineer Jon Woodward is planning on implementing a swap of the Solar
Array Drive electronics from side-1 to side-2. The reason for this swap
is that pitch noise may be caused by a broken pole in Side 1\'s motor
windings and a switch to side 2 will help verify this possibility.

See illustrations 15-19 for a summary of N18 performance over the past
week.
