**COMMENTS/CHANGES:**

NOAA-12 The battery voltage lows continue to fall on N12, yesterday
reaching 19.7 volts. EMOSS power engineer Carl Gliniak

is closely monitoring this situation although thorough analysis of N12
is difficult because of its minimal number of passes and very incomplete
data volume. The PSSS battery voltage trigger levels on N12 is 18.7 V.
Battery temp and charging remain nominal and enough power continues to
be generated by the solar array. However, the peak eclipse duration is
still as much as 2 weeks away so these voltages can go lower by another
0.3 to 0.4 volts. Should, a transmitter inadvertently be left on another
half volt or more could be subtracted from this equation which is very
close to the PSSS trigger value. Since this is the same scenario that
triggered a safestate on N12 last year EMOSS engineers remain concerned
about the potential for another such incident this year. EMOSS engineers
have notified POES controllers that they should ensure that all
transmitters are turned off prior to LOS even if it will result in lost
data.

NOAA-14: Spacecraft is operating nominally and power subsystem remains
stable and above safe state threshold values as the

long slow increase in percentage darkness time per orbit continues
through mid-June 05 (illustration 1). Otherwise there were no changes to
N14 during the past reporting period.

NOAA-15: The N15 AMSU's were all generally stable and nominal during the
past week (illustration 2) as was the N15 AVHRR (illustration 3). The
N15 HIRS filter motor current remained at its near historically low
values last week although there was just a hint of instability relative
to the past two weeks (illustration 4). Finally, N15 is progressing
nominally through its eclipse season (illustration 5) which will reach
peak darkness per orbit within the next 2 weeks. No power subsystem
reconfigurations are expected.

On 27 May at 18:30z the N15 STX-2 (omni) used for HRPT data experienced
an abrupt drop in output power to 3.5 watts. After several minutes, the
power increased to approx 5.5 watts where it has remained since that
time. At the moment the power drop occurred, the STX-2 temperature
increased for a short time after which it decreased and is now running
lower than it had previously (illustration 6). EMOSS has received no
reports of degraded HRPT imagery as a result of this situation.
Furthermore, EMOSS analysis of N15 HRPT imagery shows no obvious affects
(illustration 7). In response, engineer Will Chadwick has generated and
distributed an Event report and a TOAR.

NOAA-16: The N16 AVHRR scan motor current continued its slow increase
into higher mean values for the seventh week in a row

(illustration 8). Furthermore, the synch delta on this spacecraft
continues to degrade into frequent anomalous values (illustration 9)
requiring actual MIRP rephases on just about every orbit many orbit
(rephase is enabled over the South Pole on every orbit (illustration
10). HRPT imagery also continues to experience frequent wave patterns
(illustration 11) although no bar code patterns have been seen since 22
May. The frequent MIRP rephasing is probably the reason why bar codes
have not yet become prevalent. Regardless, the trend on this payload is
unfavorable and if it does not reverse this trend significant imagery
problems are a likely result.

The N16 HIRS was relatively stable and nominal last week after
recovering from a slight filter motor current surge the previous week
(illustration 12). There have been no additional reports on the quality
of the N16 AMSU-A1 products since last week although EMOSS is assuming
they have not improved. AMSU-A1 on N16 continued to perform nominally
from an engineering perspective.

ON 1 June at 00:01z BTX-2 was turned off because of an RF conflict with
N14, and remains off at this time. Since N14 is a secondary spacecraft
relative to N16, this was unexpected. EMOSS has requested that the
Scheduling group look into the decision making aspect of the SOMS code
to determine if this turnoff was correctly chosen. Will Chadwick is
EMOSS POC.

NOAA-17: The N17 AVHRR, HIRS and remaining AMSU's on N17 were nominal
and stable during the past week (illustration

13\. There were no changes to N17 in the past week.

NOAA-18: To date, the N18 OV checkout has continued to proceed nominally
and by this time next week, should be concluded

with N18 operations transitioning up to the SOCC for integration with
the other POES spacecraft on 8 June at 12 noon local time. The primary
area of concern at the present time continues to be the Z (pitch)
Reaction Wheel motor currents which are running significantly higher
than any other spacecraft pitch wheel has ever run. The focus of concern
revolves around the possibility that the proportional and integral gains
for NOAA N Pitch (Z-axis) RWA control law algorithm are not correct and
will require a software patch to the spacecraft to alleviate. This
software patch has been created and is scheduled for upload on 7 June
with Jon Woodward overseeing the operation. Another concern is that of
spikes in the DDR current that usually, but not always occur at the day
night transition stage. This situation has continued but is not
considered a serious concern. Much has occurred on N18 since the
previous report and spacecraft health remains nominal (see sample
illustrations 14-26) A quick review of major operations and testing
since the last report follows:
