Pass Summary:
Completed a successful recorder dump.  Performed a 2-part attitude
maneuver to repoint the HGA.  Performed SWEPAM-I igh voltage ramp-up
activities

Anomalies:  Failure of backup fanout 3 box over the weekend
necessitated a reboot.  Reboot caused a break in data reaching ASC from
1843 to 1930.  The connection was re-established on time to complete the
SWEPAM activities.
The IP NOCC is reviewing all the connectivity issues with ASC.

Summary: 
Today's pass include a ~3 minute telemetry drop-out during an SFG swap and 
problems with the transfer of 5-16 Monitor block data from JPL to the MOC.  
Changes had been made at DSN early in the mission as a patch to put Monitor 
data in the same Isis group as Command Echo.  Somehow this patch was undone 
today and Monitor and Echo data began flowing over two separate streams which 
is incompatible with the MOC software.  Otherwise, today's pass was nominal 
and included execution of CRIS diagnostic procedures.

Anomalies:
G98-001  (DR# Not Avail)  JPL equipment swap out (SFG 1 to SFG 3)  3 min 3 
sec loss of Telem etry

w/d16

-------------------

Pass Summary: 
For the second consecutive day DSN 5-16 Monitor blocks were not 
transferred correctly to the ACE MOC.  The Ops Chief and IP NOCC were 
unable to help and the FOT was asked to call George Crouse at JPL (someone 
who worked on the JPL Isis interface at one time), as he and Cris Spinolo 
are the only ones who know what the correct configuration is for Monitor and 
Echo data to be received at MOC.  The FOT left a message for Mr. Crouse (who 
is is no longer working on the Isis interface) to attempt to resolve this 
problem.  Otherwise, the pass was nominal and included execution of the CRIS 
diagnostic procedures.

Activities:
1604  AOS w/D16

1940  EOT w/ 
D16

-------------------

Summary:
Nominal pass which included execution of high-voltage adjustment procedures 
for the SWEPAM instrument and the nominal CRIS diagnostic procedures.  In 
addition, although the FOT was not informed of any changes, the DSN 5-16 
Monitor data began arriving correctly at the MOC during this pass.  A change 
was made to put this data back in the Command Echo Isis group which is 
required for proper processing in the ACE MOC.  The FOT will follow up on this
 problem 
to determine how it was resolved and if any further actions are necessary to 
make this configuration the 'standard' ACE Monitor block transfer 
configuration.

EOT

-------------------

Summary:
Nominal pass which included an attitude correction maneuver.  In addition, 
the FOT set the C&DH B selectable telemetry byte to point at the C&DH A 
current reading.  This was done as part of an ongoing investigation into 
variations in the C&DH B current as read by C&DH A.  The inactive selectable 
telemetry byte will be used to see if the C&DH A current as read by C&DH B 
has the same variations (it does not vary when read by C&DH A).  If 
variations are detected it may prove that the variations are more due to how 
the 'opposite' C&DH reads the other C&DH's current.

Summary:
During today's pass the FOT dumped the active C&DH block bins (0 
miscompares) -  Checked autonomy bin enable/disable and fire flags and 
executed a SWEPAM-I CEM level change.  In addition, diagnostic 
procedures were run for the CRIS instrument.  Today's SSR playback contained 
only 11 missing frames

-------------------

Summary:
The MOC software crashed during today's pass.  Data began to buffer up in
TPOCC and event messages indicating a telemetry dropout were generated.
However Isis was queing up data during this period and then sporadically
TPOCC would start receiving data again.  This steadily got worse throught out
the pass and at 15:25z the MOC software was restarted and appeared to fix
problem.  This problem was also noted on day 009 but not as bad.  It seems
that this problem occurs when ADS program is running.  The FOT will
investigate the cause of this anomaly.  Otherwise, today's pass was nominal
with no special activties scheduled.

Anomalies:
G98-003  TPOCC system Crash  (SW recycled )

1605  Poke commands issued to active and inactive CDH (LRT)
1614  S/C commmanded to RTSW downlink format
1625  LOS w/D61

Summary: 
Commanding today was stopped 20 minutes early after the ground station 
reported that the antenna was dropping below the 10 degree commanding mask. 
The FOT was unaware that Madrid had this masking (the ACE NOPE had reported 
pre-launch that only Goldstone had a 10 degree mask).  The NOPE will be 
contacted to ensure that FDF is using the correct masking when generating 
Predicts for all sites.  Otherwise, this was a nominal pass.

Anomalies:

ACE FLIGHT OPERATIONS DAILY REPORT - Addendum

Operations Day -- 15/1998 (January 15, 1998) Addendum
Mission Day -- 144

 NOAA personnel contacted the FOT to inform us that the signal from the S/C
was lost at approximately 1920Z and that the air force station had been
unable to reacquire data
A pass was obtained with station D16 and following that with station D24.
DSN successfully locked on telemetry.
Analysis of the telemetry revealed that the loss of downlink acquisition
was due to the triggering of the RF watchdog reset on C&DH A.
Following the day's maneuvers the rf watchdog terminal count was left at 3
hours instead of 48 hours during the daily pass.
The rf watchdog trigger reconfigured C&DH A to the -Z broadbeam antenna and
switched to a data format which is not compatible with the air force
network (LR ADC) which is why NOAA lost the downlink.  The S/C behaved
nominally.

To reconfigure the spacecraft to the nominal operations state:  The FOT
reset the antenna configuration to its nominal state: C&DH-A on the High
Gain, C&DH-B on the -Z broadbeam.
All S/C subsystems and instruments were verified to be operating nominally.
The data rate was switched to RTSW.
Verified NOAA could again lock up on the RTSW data and terminated the contact.
All systems are nominal.

Summary: 
Today's pass included a 20 minute loss of telemetry due to the incorrect TGC 
software being used at D61 and problems with Isis.  During the remainder of 
the pass the FOT performed high voltage ramp up sessions for the SWICS and 
SWIMS instruments and diagnostic commanding for the CRIS instrument.

Summary: 
Today's pass was nominal with the exception that the D16 ranging 
system was down for the entire pass.  SWICS and SWIMS high voltage ramp up 
sessions were completed today along with CRIS commanding to raise the matrix 
detector threshold, SIS commanding to reset the hydrogen and helium timers, 
and SWEPAM-I commanding to continue instrument characterization using the 
on-board pulser.

Summary: 
An attitude maneuver was performed today that pushed the high-gain antenna 
angle out to 3.9 degrees (violating the 3.5 degree requirement). There was no 
observed impact on operations and FDF is analyzing why the maneuver performed 
non-nominally.  In addition, high voltage ramp up session were performed 
today with the SWICS and SWIMS instruments.

Summary: 
Today's pass included a 50 minute telemetry outage during SWICS commanding.  
This outage was caused by Nascom network problems.  Although the FOT was able 
to recover all of the day-25 SSR dump, today's problems prohibited the FOT 
from completing the day-26 SSR dump.  The result is that 1.5 hours of the 
day-26 SSR dump will be moved to day-27's dump.  At this point it will take 
a number of nominal DSN contacts to retrieve all of this SSR data along with 
the daily dumps.

Anomalies:
G98-013  49 minute telemtry outage due to ISIS(IP) routing protocol failure

-------------------

Summary: 
Today's AOS was 10 minutes later than scheduled due to problems at D66.  
Once contact was established the FOT performed the nominal SSR playback 
along with the playback of 1.5 hours of data from day 26 that had not yet 
been recovered.  To recover all of this SSR data the FOT scheduled an extra 
one hour support with D16.  A handoff was performed from D66 to D16 at 
17:05z.  Other activities today included an attitude maneuver and commanding 
to the SEPICA instrument to restart the 30kV power supply due to an out-of-
limits current reading.
