Plan: - Running NOV0600C on descending leg. Observing 3C31 with ACIS-I (obsid 2147).
	Next observation of SMC X-1 begins shortly after shift end (obsid 1027).

	Radiation levels are low now (flux of ~1000) but high value of Kp (6.0) 
	indicates that levels bear watching.

2) SSR dump went as planned, but OC/CC lost commanding due to workstation
   lockup.  Postulated SSH problems with the command string.  Support extended
   to at least Chandra auto-turnoff of the downlink to attempt to resolve
   problem.  Currently in process of changing to the third string for commanding,
   since it seems to be still working.

   Commanding worked on third string.  SSR pointers reset, Chandra xmitter off
   at 22:19.
