ACE 2 hr fluence is 9.4e4 vs. threshold 3.6e8. CRM-based orbital fluence is 4.1e7 vs. threshold 1.0e9. Chandra is in the magnetosphere. 4) Quick Look data review (OK unless noted): Obsid 2091: NGC 3783. ACIS-S/HETG. OK. 5) ACA monitor window test was successful. At the end of the maneuver, the monitor window contained about 50% of the target star. After setting dither to zero and then performing another star re-acquisition, the monitor window contained most of the energy of the target star, although the target star was offset by about 5 arcseconds from the center of the monitor window. 6) ACA dark current calibration 1130: start SOP_ACA_DARK_CURRENT_MEASUREMENT 1205: During the test setup, the PEA IU configuration command load AR_P1IUA had to be sent twice, since it was not received by Chandra on the first attempt. 1230: first ACA dark current cal completed normally. 1234: More trouble sending commands to Chandra. Commands are getting to DSS-54 from the OCC. 1240: Test command correctly received by Chandra. 1315: Another problem getting commands to Chandra, after the return to VC0 (realtime telemetry) from VC2. 1400: CPA swapover at DSS-54. 1405: Requested and obtained a 15-minute extension to DSS-54, to make up for lost time. 1500: Last dark current cal replica started. EPHIN rates have been climbing over the duration of the cals, as Chandra approaches perigee. 1545: SOP completed successfully. Cal data are arriving at the GOT. A DR will be written for the commanding problems through DSN.
