Status essentially unchanged. NOTES/ISSUES/PROBLEMS From the 9am status meeting: Five supports over the weekend. One was an additional 34m support to compensate for a DSS-66 issue. On-board loads good through 108:00:28. A previously scheduled DSS-64 support has disappeared from the schedule, leaving a nearly 24 hour gap without contact. FOT/MP will try to get this restored. APR2103A is in work, waiting for an ACIS SI_MODE for the TOO. Expect products out late today for a load review tomorrow. Yesterday made progress running ASVT testing on the IRU swap products. Have a problem with IRU-B control in the normal Manuever Mode. Will debug this today, hope to run it tomorrow. Run for record later in the week. Will have a tagup with the west coast this afternoon. Gyro A-1 current has been quiet since Friday, running about 149ma on Saturday and 151 ma on Sunday. GOT will be testing firewalls on Thursday morning.
