Shift L1763. Start at 140:12:00 GMT = 08:00am 19 May EDT End 10:00am 19 May SOT Lead DAS (Times will be given in GMT on day 140.) PLAN ---- Continue running load May1704B. This entire orbit will be obsid 4760, an ACIS-S/HETG observation of MCG -6-30-15, emphasizing structure and dynamics of the warm absorber.

Status is essentially unchanged. Ascending through 105498 km. ACIS focal plane temperature -119.7 degC. EPH temp 82.24 degF NOTES/ISSUES/PROBLEMS From Today's Space Weather: " NOTE: The ACE spacecraft orbit will bring ACE nearly in line with the Sun from about May 30 to June 2, 2004. During that time solar radio noise is expected to interfere with spacecraft telemetry resulting in the loss of solar wind plasma, magnetic field, and particle data." From the 9am status meeting: Three supports in the past 24 hours, no issues. One load segment uplinked, on-board loads good until 143:21:15. MAY2404A products out yesterday for 1pm load review today. Lack of access to ODE from command management as reported yesterday turns out to be a GUI interface problem, and does not block actual access to the ODE. Some problems have been noted with the reporting of subformat data by the ONLS EHS system. Needs to be diagnosed, but not an immediate issue since GRETA is used for checking. ASVT patch testing continues on the patch to use HRC data in the slot of the EPHIN He data. OCC made some additions to the EHS firewalls yesterday to anticipate linux migration.
