Shift report H82 October 12 1999, 21:00 EDT, GMT 286:01:00


   The  "ACIS Realtime Intervention Team" was at work again tonight.
We interrupted OBSID 18 with CAP 470.  The point was to perform some
diagnostic dumps of FEP 0 memory & BEP memory and to power-down the 
FEPs before the next observation.  Hopefully, the power-cycling will 
clear the problem and the diagnostic data will tell us exactly what
the problem was.


GMT		Event
286:00:00	AOS on DSS 54 [Madrid]
286:00:01	FMT 2, science run in progress, gratings retracted
286:00:15	start CAP 470, startScience, dump "General portion" of
		FEP memory
286:00:27	execute HWREGS1, HWREGS2, & DCACHE dumps
286:00:30	loss of com as XMTR is turned off and on
286:00:31	ICACHE dump
286:00:35	BIAS MAP dump
286:00:39	lots of TLM dropouts
286:00:50	2nd attempt to dump BIAS MAP, Peter will cobble the
		two together or use the SSR dump data
286:01:04	power-down the FEPs
286:01:09	daily load powers up the FEPs and reconfigures for
		OBSID 1386	
286:01:11	startScience
286:01:35	start BEP D Cache dump
286:01:40	LOS


Problems:

1. We skipped the dump of the Image buffer because we repeated the
dump of the Bias buffer.

2. The loads to dump the BEP D cache and I cache were inadvertently
built for the B side of the OBC.  Mark quickly rebuilt the loads for
the A side and renamed them 1A_RBDCA_201.cld and 1A_RBICA_202.cld


NOTES:

We will need to check the event data at the next few passes to see if
FEP 0 is behaving nominally again.
