times are rough, not precise.)

PLAN
Continue running load DEC1299b. Finish OBSID 624, ACIS-S of LP944-20.
Do OBSID 1508, which conducts test of the SI ground safing script,
via CAP 527. 

Next Comms:

        349:23:00 to 01:00 
	350:

16:15 Proceed with CAP 527.
16:16	Switch to format 4, normal subformat.
	verify all PCAD/SIM/OTG conditions
16:18   Switch to format 2.
16:22	Switch to format 1.
16:25	Proceed with SOP 62008 to open HRC door. 
16:35	Verify HRC door opened.
16:38	Complete SOP 62008

16:52	Verify correct initial conditions for safing script.

   


NOTES/ISSUES/PROBLEMS
Upcoming activities:
	ASVT test of the continuous dither patch on Thursday.
	Level II CCB Friday, 10:30 EST, to approve loading SCS 107
	into OBC-B and to load the continuous dither patch.
	Monday, 11am EST, start test of continuous dither patch.

No new quick look plots have been received for the past two days.

Note: we are handing over sot-lead in the middle of the safing
proceedure, so this may be confusing to follow the shift reports -- sorry.
