Shift L1719. Start at 096:12:00 GMT = 08:00am 05 Apr EDT End 10:30am 05 Apr SOT Lead DAS (Times will be given in GMT on day 096.) PLAN ---- Continue running load APR0504B. Finish obsid 5315, an ACIS-S/HETG observation of he Seyfert 1 Galaxy ESO198-G24 to study the iron line complex. Then do cti measurements surrounding perigee passage. No Comm this shift.

Triggers) P41GM = 0.0 LT 8.47 A-leak = 1.0200 mu-a B-leak = 0.9560 mu-a Descending through 125365 km. ACIS focal plane temperature -119.7. EPH temp 91.63 NOTES/ISSUES/PROBLEMS Tom Aldcroft has posted results of the aca CTI analysis by means of dithering across the quadrant boundaries. See http://asc.harvard.edu/mta/ASPECT/cti_dither The methodology of the tests is clearly working, and we will want to insert more such dither tests into weekly loads routinely. Now that we are in daylight saving time, note that GMT is only four hours ahead of local east coast time. From the 9am status meeting: Nine supports over the weekend. No issues. Three segments of APR0504B were uplinked, on-board loads good until 100:05:15. Ran CAP 750K for OBC memory dump. This is to check status of K-constants, as part of evaluating turning on the redundant abort heaters to assist in achiving higher temperatures during ACIS bakeout. APR1204 in work. Needs to include the remaining eight E0102 calibration observations (eight being done this week). Design engineer Chul Park was consulted regarding the noisy power on transmitter B. He is not concerned and recommends no action at this time. ACIS team plans to bring their software patch to the FD CCB this week. Packages are prepared, and DDTS entry is being attempted.
