times are rough, not precise.)

PLAN
Running under Load P20d.
Enter radiation belts (ACIS stop science) 12:06 GMT. 
Will exit (ACIS video on) at 22:01 GMT.
Comm scheduled 13:40 to 18:05.

Medium eclipse from 15:16 to 16:14 GMT (start 11:16am EDT).


EVENTS
Look Ahead:  ACIS to measure CTI from 278:22:01 to 279:03:05.
	Then ACIS-S science target starts at 279:03:53:26 for 
	16h20m. This is OBSID 00124 observation of SN1987A,
	with ACIS-S and the HETG.

NOTES/ISSUES/PROBLEMS
From 9am meeting:
Wallace Jackson will be verifying the procedures for short
  eclipses using ASVT. We will need level 2 approval of them
  to baseline and use for the Oct 10 and 13 eclipses.
D. Shropshire wants a meeting with science mission planning on
  Thursday, to plan the Leonid encounter operations.
