Plan: - Running FEB0402D on ascending leg. Observing CAS A (obsid 1952) 
	with ACIS-S.

        Radiation levels are very low (proton flux under 200).  See note 2.

3) HRC (Jon) reports that they have established a second connection with
   "squirt" for their backup EGSE, so they have a fully redundant system
   in case of equipment failure and for use during critical operations.
