(Times will be given in GMT on day 321. In general
times are rough, not precise.)

PLAN
Continue running load p26b. We should have finished the 
ACIS CTI measurement, OBSID 63898, and now be doing NGC7293, 
OBSID 631, with ACIS-S. At 22:37 we will maneuver to the anti-Leonid
orientation.

We will continue to watch solar activity, which is high.
Comm passes planned at 16:00 to 16:45
		       23:25 to 04:50
	       and 322:06:00 to 08:00. 
		   322:14:00 to 16:00

NOTES/ISSUES/PROBLEMS

At about 13:00, the ACE proton flux (130-214 keV) was holding around
300 per (cm^2 s MeV ster), after falling over the last 6 hours from a 
peak flux near 10^4. We are still eperiencing high solar activity,
with coronal mass ejections possibly hitting earth on Nov 17 and
19. From http://www.dxlc.com/solar/:  
	"On November 17: A major flare was observed at 09:57, it
reached the M7.4 level."
	"Region 8765 developed further and is a very complex region capable
of producing a major proton flare." 
 
Notes from 9am  meeting.
	OFLS 8.0 has been delivered. We are waiting on the new 3.6
delivery of the ONLS at which time both will be installed on string
3 and testing will begin.
	Had 3 good SSR playbacks in last 24 hours, loaded another part
of p26b. There are 3 more parts to complete p26b, two more planned to
go up in next 24 hours.
	Personnel are set for covering Leonid encounter this evening, 
with people off-shift ready to come in early-am tomorrow if needed.
