PLAN
----
Continue running load AUG2602D.  Currently safed for radiation zone 
entry.  Perigee at 243:0404; next science observation is another quick
calibration observation of Cas A with ACIS (obsid 2876), and then an
ACIS-I observation of a region of the Giant Molecular Cloud NGC 6334
(obsid 2574).

ACE EPAM P3 rates remain very low (under 100).  Forecast is for low
to moderate solar activity over the next few days.  Let us hope for
no big flares this Labor Day weekend.

 242:2030 to 2130
