Shift L1061. Start at 168:12:00 GMT = 08:00am 17 Jun EDT End 11: am 17 Jun SOT Lead DAS (Times will be given in GMT on day 168.) PLAN ---- Continue running load JUN1702C. Finish OBSID 2524, a GTO ACIS-I observation of the starburst/HII region W51. Perigee passage will follow, including the test of how close to the earth the ACA can track stars.

Descending through 102292km. ACIS focal plane temperature -119.7. NOTES/ISSUES/PROBLEMS From the 9am status meeting: Over the weekend, 6 34m passes and 2 26m passes all successful. 3 SCS loads were uplinked, onboard loads good through 172:07:03. FREEFOT1 having problems, CHOCODILE being used for GRETA relays. 3 SCS loads were uplinked, onboard loads good through 172:07:03. Tonight at 10:50EDT starts the test to see how close to the earth limb the ACA can track stars. We will be tracking 4 stars, and have 4 monitor windows. Dither will be disabled. We have real-time coverage scheduled for the duration. Contingency CAPS are all signed off to command re-acquisition of stars as they are lost. We have not yet completed the transition of OFLS 9.3 to the prime string -- still running 9.2b. Expect completion in next couple of days. Planning for JUN2400 products to be out later today for an email load review tomorrow. Tomorrow, Tuesday, at 10am EDT will be a briefing on the results of the TRW/Kodak thermal analysis study. Briefing is in the action room, and via Telecon, 405-244-5060 Pass Code 1165#. The powerpoint presentation will be emailed today.
