Shift L671. Start at 143:12:00 GMT = 08:00am 23 May EDT End 12:00 noon 23 May SOT Lead DAS (Times will be given in GMT on day 143.) PLAN ---- Continue running load MAY2101C. Finish obsid 1945, ACIS-S/HETG observation of the galactic black hole GRS 1915+105 and then do 1898, an ACIS-S/HETG observation of the magnetic cataclysmic variable AO PSC, which was originally identified with the HEAO-1 Scanning Modulation Collimator experiment.

Triggers) P41GM = 0.0 LT 8.47 A-leak = 0.6040 mu-a B-leak = 0.1120 mu-a Ascending through 115877 km. ACIS focal plane temperature -119.5. NOTES/ISSUES/PROBLEMS From the 9am status meeting: Products for MAY2801B are out, will be reviewed at 2pm today. Yesterday's real time CAP to do ACIS raw mode cuckoo clocking was successful. These measurements will be repeated in stored command loads. They will give data to better help us understand how charge deposited downstream from an X-ray event of interest influences the effective CTI for that event. The SOT GRETA workstation has been brought back up. A new SOT PC has been installed in the TST room, in place of the EPHIN slave terminal. Machine is on and running windows 2000, with the monitor turned off. Users will need to configure X-WIN32 to connect to their HEAD workstation, if desired (instructions are at the PC). ACA star selection working group will meet at 10am today.
