SOT Shift A Report (continued)
IUS phase

Things went very smoothly except for some commanding
problems from Diego and a slightly non-nominal orbit
after the IUS burns:
Apogee is 72020km. Expected=74097 km
Actual perigee=330.23km; Expected perigee=327km
Expected FINAL perigee after IPS5= 10,260km if
IPS5 occurs at MET 13d17h41m, couple of days later
than scheduled.

8:18MET	SRM Burn 1
	no downlink to P-3 to confirm burn - blockage by Chandra
8:22	SRM Burn 2	
8:32	Acquisition at Diego - all Nominal, both burns
		-FORMAT 4-
	ACIS radiators may have caught some (indirect?) sun
	Cold Radiator at MET 7:44 = -40.0C
	Cold Radiator at MET 8:32 = -33.0C
8:46	Solar Array Deploy Begun
8:50	Microswitches indicate arrays fully extended
9:11	Confirmation arrays connected to bus: 31.2 V
9:18	IUS Separation Confirmed
9:52	Acquisition at Madrid
10:28	Non-nominal Orbit.
	Apogee is 72020km. Expected=74097 km
	Actual perigee=330.23km; Expected=327km
	Expected final perigee after IPS5= 10,260km if
	IPS5 occurs at MET 13d17h41m
10:31 	Diego commanding problems causing some delays
	IPS activation will be done (hopefully!)
	after shift change to B
10:52	ACIS, HRC temperatures nominal
11:07	Handoff to B SOT lead
