The eclipse performed nominally for each spacecraft. Further analysis
will be completed over the next few days. A ZIP file (renamed .TIP for
NASA) is attached to the email containing the eclipse plots for each
spacecraft. Additional information related to eclipse is noted under
individual spacecraft status headings.

Our recommendation should be to increase number of passes on N-12.  At
present we are at 40% of the day leaving 60% uncovered.  The 96 day on
orbit plots should no signs of bus voltage spikes.  Looks like a shunt
going bad, same kind of behavior last fall.

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

A N12 YAW update happened during the start of eclipse and another one at
the end of eclipse.  Both were with better then 95 % sun.  This was a
non issue.

NOAA-14: NOAA14 continues to be in YGC mode.

DTR 5A is inoperable. The problems appear to have begun at 071/22:26:00
(see Figures 1-6). Post-pass analysis by engineering confirmed a sharp
increases in current and temperature. Plots also showed that playback
voltage was constant throughout the pass. Pressure was fairly constant
hovering around 11 psi throughout the test of the recorder, which is
unusual for a recorder that has record and playback pressures of \~15
and \~18 psi respectively.

On Jday 072 at 01:00z, NOAA-14 was noted by POES controllers to be in
record and at EOT (End of Tape) during rev. 62905. A call-up at 02:52z
was performed by the POES controllers in an attempt to playback retrieve
and data . During this call-up, DTR5A was issued a play directive at the
start of the pass, however no frames or modulation were received. Back
orbit analysis by controllers indicated that DTR5A was EOT when placed
into record at 22:30:10 on Jday 071. At the beginning of the contact,
the recorder was found to be EOT and moved to NOT (Not EOT) after the
playback command was sent.

At 20:02z (rev. 62914), another call-up pass was performed at the
request of engineering in an attempt to get the recorder to playback or
record data and to determine the status of the recorder. At the
beginning of the pass the recorder was NOT. A STIP (Stored TIP) playback
was then issued, but no frames or modulation were received. Next a GAC
(Global Area Coverage) playback was attempted. This was done because GAC
records and playbacks spin the reel of the recorder at a faster rate
than STIP. Just like prior attempts, no frames or modulation was
received. A GAC record command was then issued and moments after this
command was sent, the current jumped up to its maximum limit of 662.70
mA. A normal record current is usually \~300 mA and playbacks are \~600
mA. A steep increase in temperature was also noticed in the telemetry
during this time (from approximately 23-32 degrees C). Engineering
declared the recorder inoperable and aborted the rest of SCR-442 with a
final stop command sent to DTR5A.

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

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.

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 except for the MHS (see below)
for the past week. The EPS and ADACS subsystem has been performing
nominally.

The MHS has operated nominally since the Day 068 incident and subsequent
Day 070 return to nominal. Investigation into this event and its return
to nominal values is ongoing.

During the 19 March eclipse, the N18 SADPOS timer went for 11:10
minutes; the threshold is 12 minutes.

The proposed HIRS/LRPT test has not occurred yet due to an increase in
the noise of the HIRS. It will be placed in space view, and the APT and
beacon transmitters turned off. The instrument and transmitters will
then be returned to their original configuration at the end of the same
contact. This operation is only expected to take 1 contact. This test is
still in the "proposed" phase, and notifications along with approval for
the test still required.
