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

1) The Chandra snapshot was not available because of telemetry decom 
problems on psicorp. These should now be fixed.

3) Radiation
   ---------

Chandra Radiation environment is low.

ACE 2 hr fluence is 2.6e5 vs. threshold 3.6e8. 
CRM-based orbital fluence is 7.9e7 vs. threshold 1.0e9.

Chandra is in the magnetosheath.

4) Quick Look data review (OK unless noted):

There were no new quick look data in this shift.
