Shift report L59 September 19 1999, 11:00am EDT, GMT 262:15:00


GMT		Event
262:10:00	AOS on DSS 46 [Goldstone]
262:10:42	ACIS FP at -102.1 C, altitude 88,000 km and dropping
262:10:46	execute SOP 61071, Cold Boot
262:10:48	start SOP 61007, Load Standard and Optional Patches
262:11:00	complete SOP 61007
262:11:08	execute SOP 61010, Start DEA HKP run
262:11:09	FP temp = -106.3 C
262:11:10	execute CAP 431A to set the FP to -110 C
262:12:25	FP temp stable at -109.4 C
262:12:28	confirm obsid 1304
262:12:34	confirm receipt of start science
262:13:00	confirm end of biases
262:13:05	getting 215 c/s, about right for the cal source on S2
		and S3
262:14:20	SOC reports last dump was performed at ~6:00 GMT, so
		we will let this science run finish and then dump the
		SSR so that we have all the data on the ground
262:15:12:23	confirm stopScience (backlogged because of TLM)
		this is interesting, it took 2m23s to get the command
		echo because the TLM buffer was full

		S3 889644 cts in 7942s ==> 112 c/s
		S2 571504 cts in 7942s ==> 72 c/s

262:15:13	altitude 60,000 km
262:15:19	confirm shutdown for rad belts
262:15:21	execute CAP 442 to power-down the FEPs before eclipse,
		ACIS is now in its thermal standby state for eclipse

Notes:

- Note that the cold boot, standard & optional patches, starting DEA
HKP run and resetting the FP temp to -110 C took a grand total of 24
minutes to execute in realtime.  The standard and optional patches
procedure took only 12 minutes to execute.  This should allay our
pre-launch fears that patching the ACIS flight SW would take too long
to fit within a pass.

Upcoming Events:

- Chandra has its second eclipse ocurring at 262:18:03
- Radiation Belt passage at 262:15:19 to 263:01:50
