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

1) There was one problem during execution of the SI safing script, I_SAFEINST.
   When the "START SCRIPT O_PROT_SCSCTRL( "ACTI", %U38 ) line was executed the
   sub-script was not executed, but instead the pointer was moved to the top
   of the main script. This problem will be looked into by the FOT.

2) Chandra's state at AOS 349:2300 was:

3) Three quick-look plots from Joy were examined and looked OK (to me).

4) unagi went off the net for a while due to a cable problem in the junction room.
   This was fixed in about 2 hours.
