Plan: - Running JUL3000B on decending leg out of radiation zone.  Should
	have just completed Comet c/LINEAR (P/Tempel 2) observation series.
        [According to the DOT, there are 16 OBSIDs in this series (2 groups
	of 8) :  586, 1762-68, and 1747, 1830-36.]  At AOS, beginning RAD 
	zone entry functions.

2) Radiation levels are OK:

     ACE Proton Flux        =         81   (2 hr avg in 130-214 keV proton channel)
       Fluence (130-214KeV) =     1.02e7            LT 3.6E+8 Radiation Level OK
     Kp Index (Costello)    =       3.7                       LT 6 is OK

3) Problems with COMM for SSR playback with DSS-66.  Commanded Chandra to a lower
   data rate at ~214:2130 to see if the dump can be completed.
