Shift L3620. Start at 170:12:00 GMT = 08:00am 19 Jun EDT End 10:00am 19 Jun SOT Lead DAS (Times will be given in GMT on day 170.) PLAN ---- Continue running load JUN1509B. Finish obsid 10822, an ACIS-I observation of the cluster of galaxies MS0735.6+7421 to study the shocks, cavities, and their relation to the radio emission. Then do obsid 10920, an ACIS "undercover" calibration observations to measure ACIS background rates, while HRC points far off-axis at 31 Com. Then into perigee passage.

ACIS focal plane temperature -119.9 degC. EPH temp: 103.64 degF NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three supports over the past day. No issues. A source in the JUN2209 loads, 4U 1608-52, obsid 10061, has gone into outburst, and may require a "reverse ToO" to pull from the loads. The rates are not currently an issue for ACIS damage, but would lose the scientific objective. Eighth eclipse of the season was nominal, ninth eclipse is tomorrow. Solar rates continue extremely quiet.
