PLAN
----
Continue running load JUL0104A. Doing cti measurement during ingress
to perigee. After egress do obsid 4605, an ACIS-S GTO observation of
the Anomalous X-ray Pulsar RX J1708-4009, to perform
phase-resolved spectroscopy of the pulses. 

Next Comms:
184:1115 to 1215
184:1900 to 2000
185:0250 to 0450
185:1045 to 1145
185:1945 to 2045
186:0250 to 0450

NOTES/ISSUES/PROBLEMS
From the 9am status meeting:
Three supports in the past day, no problems.  On-board loads good
until 187:03:04. 
Products for JUL0504C were signed off, awaiting uplink.
ASVT dry run of the eclipse products was not successful
yesterday. Will try again today.
Peter Ford reports that the ACIS DPA current dropped at the time the
obsid 5008 data taking ceased with the message: "SMTERM_FEP_IO_ERROR,"
thereby confirming that the FEP were indeed reset. This is the only
case in the mission of a FEP reset without a well understood cause
(typically it is caused by an SCS 107 run).
There will be a community technical review of the day 200 (July 18)
eclipse products and procedures at 11am today, 405-244-5060, pass-code 1165#
