NOTES/ISSUES/PROBLEMS
From the 9am status meeting:
     Three supports in the past 24 hours. No issues. Last segment of 
APR2604A was uplinked, on-board loads good until 123:22:15.
	 MAY0304B loads were approved yesterday. 
	 Some ASVT testing of products will continue today. 
     Will swap data stream during test of data flow to CXC, for 
trouble-shooting psicorp.  Will see 5-10 s drop in data packets when
Packet Routing Table is changed, but they should come right back
up. Will occur during pass at about 3:15pm today.
