(Times will be given in GMT on day 180. In general
times are rough, not precise.)

PLAN
Continue running load JUN2500d. Finish ACIS-S observations of
the bulge of the Sa galaxy NGC 1291, OBSID 795; and of the jet in the
radio galaxy Pictor A, OBSID 443. Then do CTI measurements surrounding
the perigee passage. The egress CTI will actually be Squeegy VII
testing, run under CAP 625A. This CAP has been approved and is getting
signatures. The goal of this test is to get the best energy
resolution, but without creating any extra dead time (e.g., as happens
when the vertical shifting is slowed). 

Next Comms:
         180:14:15 to 15:15
         180:22:10 to 02:20 -- Squeegy VII CAP, "minumum dead time"
	 181:09:00 to 10:00
	 181:17:50 to 19:50
	 182:03:50 to 05:50
	 182:11:55 to 13:55

NOTES/ISSUES/PROBLEMS

HETG operations meeting continued all morning. Scenarios for the
near term (through end of August), medium term, and long term
operations were defined. A weekly followup telecon will be held
Wednesdays at 3pm EDT.
