PLAN
----
Continue running load OCT1705B. Performing CTI measurements
surrounding perigee passage. Upon egress do obsid 5399, an ACIS-S/HETG
observation of the normal O-star HD93250, to characterize the detailed
X-ray line spectra of stars thoughout the O-type sequence.
No Comm this shift.

294:2010 to 2210

NOTES/ISSUES/PROBLEMS
From the 9am status meeting:
Three supports over the last day. Problem with DSS-16, no ranging
available, suspect a switch is bad. Last segment of OCT1705B was
uplinked, on-board loads good until 297:03:00.
Working on OCT3105 loads.  There is an issue with two phase
constrained observations, which cannot be done unless the time
constraint is relaxed or an EPHIN waiver obstained.
Lunar eclipse plan for Nov 1 was approved at the FD CCB yesterday.
Note that the Leonids are not expected to be an issue this year, and
no action is planned.
