	Pass Summary:
	  Test pass with Madrid's D54.  Initially unable to lock up on the
spacecraft's receivers, but after corrective action taken all was well.
Successfully tested commanding, telemetry, tape recorder dump.

	Anomalies:
	     * G98-0245 - D54 was using a sweep range of 30 kHz, while ACE
now uses one of 60 kHz.  After correcting this discrepancy, site was able
to lock on the Spacecraft's receivers.

	Pass Summary:
	Support ended prematurely due to masking at site. Timetag bin
comparison was not completed. Poke commands were not sent at the end of
day, and timetag bins were not loaded for automatic data rate change for
next days AOS.
	The console team nofitied the Ops Supervisor. Upon verifying the
s/c status before support was terminated, and verifying that the LOS
timetag bin had been loaded earlier in the pass to change the data rate to
RTSW format at EOT, the station was released.
	Both NOAA and AFSCN operation centers were contacted in regards to
the ~.5 hour data loss. Preparations were made to next days pass plan to
manually switch data rates.

	Anomalies:
	     *  G98-0288 - DR #L02761  -   Although ACE had set at 16:02:27
at Station D61, the pass had been  scheduled to end at 1630.  The error was

repeated.
	The instrument team detected an anomaly with the instrument.  The
OCR only patched one of the required memory locations.  This caused the
instrument to branch to an unspecified data format.
	The instrumenter requested an emergency in order to command
SWEPAM-E into a safe mode in order to prevent any damage to the instrument
if it was not shut down immediately.


	Anomalies:  The memory poke put SWEPAM-E in an unknown state (see
AR #S98-0022).  SWEPAM-E engineers saw that it was not returning valid data
and declared an emergency.  ACE FOT began steps to recycle the SWEPAM-E
DPU.
	The processor was halted and will be repowered tomorrow, after
further analysis (OCR SWPX-008).

Emergency commanding to

	Anomalies: Emergency commanding to SEPICA covered under OCR SEP-044
(see anomaly report
	#S98-0023).  The instrument team believes that the telemetry
indicates that Fan 2 may be broken.  The commanding set the Fan 3 pressure
to zero so that the S3DPU will stop opening the remaining Fan 3 valve every
3 minutes.
	This action puts Fan 3 in a safe condition until the intrument team
can thoroughly review the housekeeping data
