(Times will be given in GMT on day 218. In general
times are rough, not precise.)

PLAN
Do ACIS continuous clocking raw data
Perform an SSR playback
Review and upload IPS-5 Burn load.

EVENTS
18:00   Change to OBSID 62720 and start ACIS continuous clocking
	raw data acquisition.
20:52   Change to OBSID 62719 and continue ACIS continuous
	clocking raw data acquisition.
23:10   stop science run, 

approve ips-5 plan

23:30    Use new OBSID, 62478, for the IPS-5 burn sequence, 

00:40   SHIFT change, B15 to A16.

23:12	Start SSR playback.

NOTES/ISSUES/PROBLEMS
Rework of the timeline shows the following sequence of upcoming
events:
IPS-5 burn, 1:45am EDT Saturday.
Slosh tests, 4 to 8am Saturday
10am Meet me telecon to evaluate slosh
	888 452 9848
	passcode 15907 #
~10pm Sat night, committment to NOGO IPS-6,  (We want a second 
measurement to confirm our final orbit.  Tolerance is only 
about 15 km).
10am Sunday, start ACIS bakeout. 
2pm Sunday, open ACIS door.

Preliminary results of CAP 167 thermal perturbations experiment show
sensitivity of .3arcsec/degC to periscope diametrical gradient.
This test turned off first the OBA thermal control, and then 
the Telescope thermal control including removal of the 
periscope control. Detailed analysis to follow.

EHS header time stamp at day 218:01:45 transitioned from 
GMT to MET. GOT has no current explanation for that transition.
This header is called the "countdown time" -- why was it
reading GMT before? It is delivered from TDS (what is that?).
Transition occurred during a telemetry dropout of ~100 
packets.
