PLAN ---- Continue running load OCT3000c. Finish ACIS-S OBSID 1958 of the center of the "mixed morphology" supernova remnant W44. Do ACIS-I OBSID 547 of the cluster V1701+6414, to determine H_0 and q_0.

NOTES/ISSUES/PROBLEMS We are now on eastern standard time, EST. Add 5 hours to local time in Cambridge to get GMT. SIRTF ops team is visiting today and tomorrow for briefings on Chandra operations. From the 9am status meeting: 2 supports, 2 SSR dumps, all was well. The routine CAP 563a was run to status the CPE counter, and gave the expected result of 1. Mission planning products are out for NOV0600 load. Review at 2pm today. The predicted times for the lunar eclipse were within 30 seconds of those calculated. Our operational tolerance was at least for a 30 minute error. An emergency Flight Director board meeting yesterday discussed a strategy proposing SSR pointers be reset prior to the next dump instead of following the current dump. Actions are to update the Standard Operating Procedure governing the reset, and to investigate how ofter the roll-over would have occured in the past just due to variations in the nominal 8 hours between DSN passes. The plan is that the revised procedure will be presented to the Flight Director Board for approval when ready. DB1 (data base server) was successfully exported yesterday. Will be imported to DB3 today, and be backed up overnight. The export/import process is necessary due to changes in the supported database version in the new ONLS revision.
