NOTES/ISSUES/PROBLEMS
From the 9am status meeting:
Three supports over the past day. No issues. Last segment of JUL1904B
was uplinked, on-board loads good until 208:07:56.

There was some confusion over three CAP's listed on the ops report
web page with no times. We believe they were not run. They are pending
CAP's to be run for the last short eclipse, and at the end of eclipse
season. 

FD CCB yesterday approved the Leonid Meteoroid Impact flight note,
and the change in SCS 101 patching to accomodate safe mode transition
loading. 

ASVT testing of IRU swap scripts was successful yesterday. ASVT tests
will be continuing over the next several weeks.
