Plan: Ascending after perigee, in belts, radiation safed.  Then
CTI measurements followed by a 100ksec ACIS-I NONE observation of
NGC 604, a massive star forming region in M33 (OBSID 2023) at 
187:23:22:47 GMT.

CURRENT STATUS
--------------
Happily tracking 6 stars.  Beyond that, see note 3.

RADIATION SUMMARY			
-----------------			
In belts; no relevent radiation information.  External (solar wind)
environment very benign (ACE EPAM P3 rate ~20) currently.

NOTES/ISSUES/PROBLEMS
---------------------

(1) ACIS focal plane temperature reached an unusually high peak during
this perigee pass.  P. Plucinsky sent email to FOT regarding this, as
the slow recovery will most likely render the post-pass CTI measurement
useless.

(2) DSN schedules for the coming weekend have changed.

(3) Chandra's state just after AOS was:
