Shift L1785. Start at 162:12:00 GMT = 08:00am 10 Jun EDT End 10:00am 10 Jun SOT Lead DAS (Times will be given in GMT on day 162.) PLAN ---- Continue running load JUN0704B. Finish obsid 4500, an ACIS-I observation of the young star systems and the diffuse X-ray emission in the Arches cluster. Continue ACIS-I observations; obsid 5182 of epsilon Pav to search for beta Pic analogs; obsid 4982 of the massive cluster of galaxies DLS J0518-4849; and obsid 5033 to continue survey of the Daddi field of extremely red objects.

EPH temp 35.95 deg F 12:53 Enter normal maneuver mode 12:56 All stars lost. Change to obsid 5182 13:13 LOS. Descending through 125318 km. ACIS focal plane temperature -119.5 degC. EPH temp 35.95 deg F NOTES/ISSUES/PROBLEMS The EPHIN A-leakage current makes a rare excursion below 1.02 mu-a saturation level, due to the low temperature of 36 deg F. From the 9am status meeting: Three 34m supports in the past day. No issues. On-board loads good through 165:12:37 JUN1404A products out yesterday, load review at 1:30pm today (note non-regular time). Flight Director board meets at 2pm today. Expect to run the monthly ephemeris update CAP tomorrow. SAO will be on federal holiday tomorrow. FOT will have a regular work day.
