Chelle and Nathan,
	sorry about this. I replied to the ATS-file message, but I 
didn't reply-all. So the following went to


Ibex Mission Operations <ibexops at gmail.com>


on Wednesday at 15:13 CDT.

-----------


All,
	checked over the ATS. I approve.

	Each of the contacts lines up with a ground-scheduled contact 
time (within 3 seconds or so).

	PL ascending and descending times match the STF, per Ken's 
script, and occur at reasonable times.

	The pointing maneuver points us in safe directions at the 
time of the maneuver, at O093 Ascending and Descending times:
