**COMMENTS/CHANGES:**

NOAA-12 As the spacecraft eclipse season approaches its maximum
percentage darkness per orbit (expected on or about 20 June)

the battery voltage lows continue to fall on N12, yesterday reaching
19.6 volts. With a PSSS battery voltage trigger levels on N12 at 18.7 V,
EMOSS engineers are concerned that a transmitter inadvertently left on
for an extended duration may draw the battery voltage down to this
trigger point as it did in July of 2004. To prevent such an occurrence,
engineers have briefed the crews to considered transmitter turnoffs a
high priority for N12 and are considering lowering the VT on each
battery to 3 (from 4). Carl Gliniak is EMOSS POC for this subsystem.

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

percentage darkness time per orbit has now peaked and should stabilize
at or slightly below this 20% darkness per orbit value for the remainder
of the year. Otherwise there were no changes to N14 during the past
reporting period.

Discussions are ongoing regarding the TBUS replacement of N14 with N18
no changes have yet been implemented.

NOAA-15: The N15 AMSU's were all generally stable and nominal during the
past week (illustration 1) as was the N15 AVHRR and the HIRS
(illustration 2). N15 continues progressing nominally through its
eclipse season (illustration 3) which will soon reach peak darkness per
orbit (estimated to be 18 June). No power subsystem reconfigurations are
expected. There has been no change to the STX-2 situation on N15 which
experienced a significant drop on 27 May. The transmitter continues to
transmit HRPT data at approximately 5.5 watts down from the previously
nominal 7.5 watts. EMOSS engineers have seen no indication of HRPT
imagery degradation as a result of this event nor have any HRPT user
complaints been received.

NOAA-16: The N16 AMSU's continue performing nominally, from an
engineering perspective (illustration 4) although there have

been occasional reports received by EMOSS engineers of degraded products
on some channels. The N16 AVHRR scan motor current continued its slow
increase into higher mean values for the eighth week in a row
(illustration 5) with synch delta values "pegging out" on nearly every
orbit (illustration 6). Each orbit, over the South Pole, the MIRP
rephases because of these high synch deltas thus losing a frame of data
as it resets the value. However, within half a rev, the value is again
pegged and requiring reset. EMOSS analysis of AVHRR imagery
(illustration 7) shows the effects of this situation with nearly every
GAC image containing a lost frame of data over the South Pole and nearly
every HRPT image containing wave patterns. On the positive side, this
frequent rephasing of the MIRP may be the only reason why bar coded
imagery has not become prevalent, yet, a situation that may change if
the scan motor current trend continues this way much longer.

The N16 HIRS was stable and nominal last week (illustration 8) although
some channels have been reported to be experiencing radiometric noise.

BTX-2 remained powered off because of a SOMS identified RF conflict.
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 AMSU's, AVHRR, and HIRS were nominal and stable during
the past week (illustration 9 and 10). There

were no changes to N17 in the past week.

NOAA-18: Operational responsibility for N18 was passed to NOAA on 9 June
at 12:00z with the OV period scheduled to continue

through 3 July 05. Major operations that occurred on N18 between the
previous report and this one are as follows:

6/7/05 23:55 AMSU-A1 to space view-1

6/8/05 01:35 AMSU-A2 to space view-2

6/8/05 13:40 SBUV range-3 to anode

6/8/05 20:25 HIRS scanner park at warm target

6/8/05 22:05 HIRS to full scan mode

6/9/05 12:00 Operational responsibility to NOAA

6/9/05 13:35 HIRS scanner park at space view

6/9/05 15:15 HIRS to full scan mode

6/9/05 20:00 STX-4 turnoff (AIP data)

6/13/05 17:40 DCS DRU-8 turnoff

6/13/05 19:15 SARP bandwidth profile changed from 1 to 2

6/13/05 19:20 SBUV flex memory-1 reload

6/14/05 19:05 SBUV flex memory-1, segment 2, memory test (load 0's and
f's)

PLAN 6/15/05 12:30 SBUV Flex-2 memory load (with previous flex-1 load)

N18 (cont)

In general the spacecraft is operating nominally (see illustrations
11-19 for selected subsystem analysis graphs). However, there are
several problem areas that are under investigation, some or all of which
may (or may not) result in TOARS being generated at a later date. These
areas are as follows:

> Excess pitch values (relative to previous spacecraft) and Z-wheel
> currents (both of which are within spec but outside expected values).
> On 7 June a software patch was uploaded that changed a threshold in
> the rate nulling algorithm. Additional patches may be required pending
> the outcome of the investigation into this situation.

DCS DRU-8 inoperability. DRU-8 was turned off pending additional
analysis.

> HIRS degraded imagery on channels 1-12. Tiger teams have been meeting
> to analyze the situation and determine its cause and resolution.
>
> DDR current spikes. Not considered a serious problem and all DDR's
> appear to be full functional. However, this situation remains under
> investigation.

One other area of concern was the SBUV flex memory-1 which was not
echoing back all the same words that were being loaded into it
(especially segment-2). A tiger team consisting of EMOSS, Aerospace,
NASA and NOAA engineers investigated this situation, ran several tests
and with the help of a NOAA DMSP engineer determined the cause to be a
"clerical error" in an SBUV spreadsheet that defined the SBUV OV memory
loads. Corrections to the table are a simple matter but SOMS will also
be required to have corrections made to it in order to complete the
recovery of this situation. However, the bottom line is that there is no
anomaly in the SBUV as was first thought possible. Jim Walters and Sally
House were EMOSS members of this Tiger Team.

An additional attachment to the email that delivered this weekly report
is an MS Excel spreadsheet that contains all commands sent to the N18
(but not 28) spacecraft as recorded by the Flight Time Table tool. This
spreadsheet summarizes [all]{.underline} Manual, CP, SCT and Scheduled
commanding (including NOOP's) that took place between 20 May 11:48z and
11 June 02:45z. It also includes the major operations that have occurred
since 11 June 02:45 through today, 14 June 19:10z. This file will allow
the user to search and sort on any number of different combinations of
data including subsystem, command type, site, rev, time, etc. (Note the
file is rather large, 5100 rows.) Jeff Devine is EMOSS POC for
generating and distributing this file. It is the combination of all the
EMOSS Command Engineer's work that occurred during the OV period.
