Plan: - Running JUL3000B on ascending leg well out of radiation zone.
        Now observing NGC 6397 with ACIS-I (OBSID 79), followed by 
        two more ACIS observations and then a series of comet
        LINEAR observations tomorrow starting at 214:1312.

2) Radiation levels are very low:

     ACE Proton Flux      =         49 (2 hr avg in 130-214 keV proton channel)
     Fluence (130-214KeV) =         3.64e+06       < 3.6E+8 Radiation Level OK
     Kp Index (Costello)  =         1.7            < 6 is OK

3) Star/FID tracking OK.  Noted a motion "blip" in AOACYAN{0-2} (FID)
   positions starting around VCDU 5188800.  I assume it to be a heater
   cycling, but there is no corresponding motion in the Z angles.  Not
   significant magnitude (0.07 arcsec), but a curiosity.
