Operations Day -- 306/1997 (2 Nov 97)
Pass Summary: 
Nominal pass with full SSR data recovery achieved.  One spacecraft anomaly 
was encountered during the pass when the Star Scanner reset flag failed 
checking twice within an eight minute period.  Other parameters that would 
usually be reset to zero during a Star Scanner reset such as the 'Valid 
Command Count' were not reset and the Scanner data looks fine.  This anomaly 
is being investagted to determine if the telemetry may have been corrupted 
when this flag state change was identified.  In addition, the FOT has 
turned on the Scanner 'Bitestar'.  The Bitestar has no valid function on the 
ACE Scanner but it will provide a sticky telltale if the Scanner resets since 
the actual 'reset' flag clears itself within 3 major frames after it is set 
but the Bitestar value will change to 'off' and remain off until reset from 
the ground.


Anomalies:
*  At 1741 and 1749, the continuous configmon flagged that the 
star_reset parameter was <> No.  The star_syncinit parameter also flagged.

Operations Day -- 307/1997 (3 Nov 97)
Summary:
Nominal pass with full SSR data recovery.  Two separate spacecraft health 
investigations were performed today.  The first involved using the inactive C&
DH selectable telemetry byte to look at a temperature sensor (DCM1_AD1) 
that APL had told the FOT may have failed (on the C&DH B side only) prior to 
launch.  Further investigation will be performed on day 308 to compare this C&
DH B value with the corresponding C&DH A value.

The second investigation was into the Star Scanner reset flag which seems to 
be turning on and off throughout the day.  This anomaly is being investigated 
as potentially a TPOCC database problem since the Scanner seems healthy 
otherwise and the other telltales that would indicate a software reset are 
not being set.  But, since the reset flag is not 'sticky' and clears itself 
after 3 major frames, the FOT, with APL concurrence, has set the 'Bite Star' 
flag via ground command.  This flag, which is not used by the ACE Scanner 
software, will act as a sticky telltale if a reset occurs since only a reset 
will turn this flag to 'off' where it will remain until commanded from the 
ground.


Anomalies:
G-0074   TPOCC display crash on AC1XT3   - no impact to operations
S-12         Star Scanner command rejected   - cause: The Bite Star 
command is uplinked in two pieces which must arrive at the Scanner 
within one major frame of each other.  Ground delays resulted in the 
second half of the command not reaching the Scanner in the alloted time - 
therefore the command was rejected.  Impact: The Star Scanner command reject 
incremented to 1.  The command was resent within the timing allowance and was 
accepted.

Operations Day -- 309/1997 (5 Nov 97)
Summary:
Good pass with one data drop out of ~3 minutes caused by problems at JPL.  
Commanding was performed for the SWICS, CRIS and S3DPU instruments.  
In the case of S3DPU and CRIS, some commands were rejected by the 
instruments.  One of the CRIS commands, which had been successfully sent in 
earlier command sessions, was not accepted by the instrument.  The instrument 
team is investigating the possible cause of this rejection.  Additional 
commands sent during this session were accepted by the CRIS instrument and 
processed normally.  Commanding to S3DPU involved loading a table that 
required 48 separate commands. When this load was uplinked the instrument 
rejected all 48 commands. Additional commands sent to the S3DPU were 
processed without errors. The S3DPU team is investigating this anomaly.   
Lastly, a SWICS high voltage ramp up session was completed without problems. 

Anomalies:
AR#G-0075   JPL com server problems  (3min 3sec data drop while playback of

BACK
Operations Day -- 310/1997 (6 Nov 97)
Summary:
Nominal pass with a succesfull checkout of new receiver software at Station 
D24.  Performed instrument commanding to the CRIS and SIS instruments.  Large 
increases in solar activity over the past few days have resulted in the Star 
Scanner False_Alarm_Count jumping from an average of ~20 per spacecraft 
rotation to a fluctuating value of between 70 and 100+.  In addition, the 
Scanner Background_Count has gone from ~0 up to ~17.  During this 
period Flight Dynamics has not noticed any degredation in the Scanner data.

Additionally, during this pass the FOT set the inactive C&DH Selectable 
Telemetry Byte to the XM_YM_FWDRAD_T at the request of APL to determine the 
status of this sensor, which had failed prior to launch.  Comparison of the C&
DH A and C&DH B values for this sensor showed that the C&DH B side sensor 
is now operating normally.  This information has been forwarded to APL and 
the ACE Project.

Lastly, an investigation into why the Star Scanner appeared to be performing 
a software reset every few minutes identified a problem with the TPOCC 
database that is causing this a number of Scanner parameters to flag 
incorrectly.  The FOT verified that the Scanner has not performed a reset and 
is healthy.

Anomalies:
1. Star scanner false alarm count STAR_FA_CNT jumped to 70-100 false alarms 
per rotation after X2 solar flare of previous two days.
2. DSN station D24 tested new Block 5 receiver exciter software at 1716 and 
1717.  No discrepancies noted at MOC.

Operations Day -- 311/1997 (7 Nov 97)
Summary:
Nominal pass which included an attitude correction maneuver and commanding to 
the SIS instrument to take advantage of the current state of increased solar 
activty.  Reduction in the severity of solar activity have occurred over the 
last 24 hours and the ACE Star Scanner False_Alarm_Count has dropped from a 
high of over 100 back down to a nominal value of ~20.  In addition, the 
Scanner Background_Count has dropped from ~17 to ~0.  It appears that no 
permanent damage was done to the Scanner during this event.  In addition, no 
effects were seen on the ACE SSRs during this increase in solar activity.

Operations Day -- 314/1997 (10 Nov 97)
Summary:
Today's pass included a thirty minute data dropout due to Nascom line 
problems between GSFC and JPL.  Full SSR data recovery was achieved and a 
significant portion of the pass was spent on commanding to both the SWICS and 
SWIMS instruments.  The SEPICA and SIS instrument teams decided against 
performing commanding that was scheduled for today.

BACK
Operations Day -- 315/1997 (11 Nov 97)
Summary:
Good pass with a brief data dropout at the end of the pass because the 
personnel at station D16 brought down their telemetry system early by 
mistake.  Commanding was performed for the SIS, SWICS, and SWIMS instrument 
teams. The SEPICA team called the MOC to check on some telemetry values but 
decide not to perform commanding during this contact.  Because the SWIMS 
instrument did not respond properly to the initial commanding session 
performed early in the pass, the FOT performed additional commanding toward 
the end of the pass which cut short the time available to redump missing 
frames of SSR data.  Even without these redumps, SSR recovery for this pass 
was over 99%.

Operations Day -- 316/1997 (12 Nov 97)
Summary:
Nominal pass (this pass was only 3.25 hours in length due to DSN scheduling 
constraints) which included an attitude maneuver  and commanding to the CRIS 
and SIS instruments.  The CRIS instrument stopped transmitting science data 
and stopped accepting commands during this pass.  The instrument team decided 
to have the FOT power-cycle the instrument to see if it would recover.  
After the power cycling was completed, the instrument began responding to 
commands and transmiting telemetry.  Additional CRIS commanding was performed 
during the remainder of the pass to configure and check-out the instrument 
and the instrument team is currently investigating the cause of this 
anomaly.  Due to the short pass length, manuever operations, and the CRIS 
anomaly, the spacecraft remained in ADC downlink format for the entire pass 
(full CRIS and SIS data is in this format).  Science format telemetry was 
being recorded during this entire period so there is no overall mission 
impact to using ADC downlink format for the duration of the pass.

Operations Day -- 323/1997 (19 Nov 97)
Summary:
Todays pass was shortened to 3.5 hours because of a spacecraft emergency that 
was declared (not by ACE) that required the use of D16 equipment.  In 
addition, ranging was not done during this pass because the Shuttle needed 
the ranging equipment for D17 support (and they have priority).  Full SSR 
data recovery was achieved today and the FOT continued investigating small 
variations in the C&DH B current.  The other ongoing investigation supported 
today was the collection of DSN AGC information in an effort to determine how 
well the operational signal strength data matches the prelaunch predictions.

Operations Day -- 329/1997 (25 Nov 97)
Summary:
Nominal pass which included an attitude correction maneuver and commanding to 
the SWEPAM E&I, and SWIMS instruments.  Todays pass had a higher than normal 
number of missing VC2 frames in the initial SSR dump (45 compared to a 
nominal day when there are less than 10).  Time required for the attitude 
maneuver and for the instrument commanding prohibited the FOT from recovering 
all of the missing SSR frames.  The remaining frames will be redumped on day 
330.

Anomalies:
14:32:00 Rcvr B was not in-lock on acquisition.  Ran G_INITIAL_CONTACT 
anyway.  Asked DSS16 to resweep, receiver was in-lock after resweep.

Summary:
Today's pass was nominal except that - once again - there were a fairly large 
number of dropped frames during the initial SSR playback.  The FOT will 
investigate this problem to determine if it can be remedied by changes in the 
DSN configuration.

Operations Day -- 332/1997 (28 Nov 97)
Summary:
Todays pass again contained numerous frame drops during the SSR replay.  
Contacted D16 - They were seeing good data.  Also contacted IPNOC who also 
verified seeing clean data.  JPL reloaded SFG but frame drops continued.  In 
addition, todays pass started 39 minutes late because the TRMM launch slip 
took priority over previously scheduled ACE time at D16.  Commanding to the 
SWIMS instrument was also accomplished during this pass.

Operations Day -- 334/1997 (30 Nov 97)
Summary:
Today pass included a large number of frame drops and a crash of the TPOCC 
Packet Extractor task during the SSR replay.  Commanding to the CRIS 
instrument was performed to take advantage of increases in solar 
activity.  During the CRIS commanding the CRIS science team noticed that the 
instrument's FORTH library may have become corrupted during the solar flux 
increase.  The library was dumped for investigation and future corrective 
actions will be planned for next week as necessary.

Anomalies:
AR S-0017  CRIS FORTH dictionary corruption caused by possible SOLAR WIND 
activity  334/16:10
