*Time: 11 am Mountain, 1pm Eastern*
Phone: 434-817-6584 rm 152, Socorro


*Attending:

LBO: Jacobs, Wainright, Ogle, Claussen, Ford, Brisken
USNO: Megan, Chris, Jon, Alan, Bruce, Matt, Phillip, Andy,

Agenda:
  • VLBA Observations
    • November Daily Observation Report
      • November was pretty nominal with any data quality issues attributed to one instance of a stuck ellipsoid or a failure to start the observing file.
    • Discussion of MkPt intensives with Wettzell.
      • Aligning with potential changes with January request.
      • Trying to characterize MkWz using Monday, Wednesday, Thursday intensive runs.
      • In order to help differentiate, a different session name is requested by USNO. What are VLBA constraints?
        • ACTION USNO: Chris will check in on use of "w" prefix
        • Fixed nature of the obs will require schedule files. Merri Sue Carter (USNO-Flagstaff) is coordinating.
        • USNO will deliver observing files to Jim Ogle and VLBA analysts.
        • VLBA would prefer a week notice for fixed-date observations but can handle shorter in the near-term.
        • ACTION VLBA: XCubes will need to be programmed to recognize that this is a USNO observation.
    • November Post-Monthly Report Review:
      • USNO: No issues seen.
      • VLBA: We will be trying to recover backlog.
    • January Pre-monthly request
      • See above for MkWz changes
      • List of RDV experiments and new experiments being run simultaneously with IVS. These are 24 hours experiments run at same time at R1.
        • Fixed time to coordinate with R1
        • Dates are known starting in January, once a month.
        • Naming convention TBD, not "s"-prefix. NO USNO preference other than being unique.
  • Open issues
    • Data Transfer Test Needed

      • USNO needs to confirm data transfer directly from Mark5C -1 . xcube-1 is done. COMPLETED

    • LBO will get locks for SSD cases (~20) and ship to sites and USNO. OPEN
    • Public directories for n & f sessions, for use by IVS
      • VLBA update: setup and seems to be working.
      • USNO: An automatic retrieval has been setup and is working.
      • OPEN: Are the MkWz files going here? Likely
  • Networking Support Contract
    • SC fiber is being lighted. Nothing else to report.
  • Correlator Refresh Contract
    • Mark and Jim provided an overview of the correlator hardware and networking approach. See attachment below.
  • Next meeting on January 10th
