**COMMENTS/CHANGES:**

NOAA-12: There were relatively no changes to the NOAA-12 health
situation during the past week. NOAA-12 shunts continue to perform
nominally.

N-12 NBAT2AT has started to trend up in temperature 4.5 to 5 degrees. 
Sun angle is changing and NBAT2A has always been sensitive to sun angle.

N-12 bus voltage is showing signs of spikes in bus voltage below 28.5.
 As the patch current gets closer to 240 mamps the shunts can not handle
the excess power for the array.  N-12 will go into summer eclipse season
in mid May.

NOAA-14: There were relatively no changes to the NOAA-14 health
situation during the past week. NOAA14 continues to be in YGC mode.

A TIP swap from side 2 to 1 was performed at 14:10z on 17 April 2007 as
part of End of Life testing. Analysis shows that there was no change to
TIP side 1. See Figures 1-4.

NOAA-15: There were relatively no changes to the NOAA-15 health
situation during the past week.

N15 AVHRR motor continues issuing increased current noise, as it is over
the last three weeks. Two plots are attached showing the 90-day trend,
and the past 10 days. See Figure 5.

NOAA-16: There was relatively no change in the performance of the
NOAA-16 payload subsystems during the past week and the rest of the
spacecraft subsystems were also nominal during this time.

N-16 bus voltage continues to drift higher, just below 28.5 volts.  TIP
drift.

NOAA-17: There was relatively no change in the performance of the
NOAA-17 payload subsystems during the past week and the rest of the
spacecraft subsystems were also nominal during this time.

NOAA-18: The payload has operated nominal for the past week. The EPS and
ADACS subsystem has been performing nominally.

N-18 had a bus voltage spike of 30.81 volts on 15 April 2007 early in
the day.  Looks like noisy telemetry during a CDA contact.  (N-17 had
similar behavior and software is looking into how GAC data replaces CDA
contact data in PACS for ABE use)  The bus current did not spike during
this time and battery voltages were nominal.

The proposed HIRS/LRPT test has not occurred yet due to an increase in
the noise of the HIRS. The timing of the sequence is still up for
debate. But commanding sequence is it will be placed in cold cal, and
the APT and beacon transmitters turned off, a wait of 120 seconds
followed by the APT turn on, then the instruments and beacon will be
returned to their original configuration. This test is awaiting
notifications of when to perform it. The products are being regenerated
based on the latest plan.

MetOp 2: All NOAA instruments on MetOp were turned off on 20 April 2007
at \~11:30z.

Status as of 24 April 2007 at \~14:00z: The NOAA instrument recovery
activities have proceeded according to plan.  At the moment, we have the
following instrument status:

-   **AVHRR** in MEASURMENT mode Part 1 (Visible Channels ON), commanded
    during the 08:37 UTC Svalbard pass.  The patch is under control at
    105K (it took approximately 2 orbits to reach this temperature). 
    Visible channel imagery on AVHRR looks good, based on the first
    orbit of data received in the EUMETSAT PPF.  The IR channels are
    still OFF, but since the patch is now under control, we hope to
    schedule the IR Channels ON during either the 13:47 UTC Svalbard
    pass or the 14:54 UTC Dongara pass (depending on MHS activities). 
    The day/night toggling has not been activated yet, but is scheduled
    for later this evening.  The instrument is currently operating in
    Day mode with Channel 3A selected.

-   **HIRS** is in OFF mode (motors running and patch control ON),
    commanded during the 08:37 UTC Svalbard pass.  The HIRS patch has
    also reached its 95K set point, also within approximately 2 orbits. 
    Electronics are still OFF, but since the patch is now under control,
    we hope to schedule the Electronics ON (visible and IR channels ON)
    during either the 13:47 UTC Svalbard pass or the 14:54 UTC Dongara
    pass (depending on MHS activities).

-   **AMSU-A1** has been successfully commanded back to MEASUREMENT mode
    (Full Scan mode) during the 10:26 UTC Svalbard pass.  Everything ran
    nominally and the instrument is configured in its operational mode
    (PLLO-1 and Cold Cal Position 1 selected).  Motor currents came up
    as expected and are in family with previous results.

-   **AMSU-A2** has been successfully commanded back to MEASUREMENT mode
    (Full Scan mode) during the 12:07 UTC Svalbard pass.  Everything ran
    nominally and the instrument is configured in its operational mode
    (Cold Cal Position 1 selected). Motor currents came up as expected
    and are in family with previous results.

-   **SEM** is still in OFF mode, but is scheduled for switch-on during
    the 13:47 UTC Svalbard pass.

-   **SARR** is still in OFF mode, but is scheduled for switch-on during
    the 15:27 UTC Svalbard pass.  This pass allows observability over
    the Canadian LUT.
