SOT Lead	Ed Kellogg

Plan: CAL-ER 2001:089:11:55
then  CAL-ER 2001:089:15:17

Looking ahead:
Monday, Apr 2	7a-12p EDT: OTG software test
Wednesday,Apr 4 3-9p   EDT: OTG flight operational testing

Notes from 9 am  meeting
------------------------
OPS: 
	Passes		3 over the last   day(s) 
	Dumps		3
	Data loss	-
	Load is good -> 092:05:40
	CAPs		-
	next passes	1800,0300
 

MP:	APR02D products approved.
	Labor problems at Canberra: expect brief walkouts with 1/2 hr
notice. We can work around these, except if they continue during next
week's OTG operations, we may need to reschedule.

S/C:	ASVT SOP testing to occur this AM.

GOT:	-

SOT:	ACE proton radiation is low at present.
	At 1000 GMT the 175-315 keV electron flux on ACE increased by two
orders of magnitude & there was an x-ray spike in GOES, indicating a
solar flare.
	At 1200 the GOES proton flux at E> 10 MeV went up an order
of magnitude.
	We may see a large increase in proton flux soon as a result of
this activity.

Mgr:	Flt dir. board tomorrow at 2 pm
