Date: January 18th 2018

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

*Attending:
LBO: Brisken, Perley, Ford, Ogle
USNO: Chris, Megan, John, Andy, Matt, Khalil, Phillip, Bruce


Agenda:
  • VLBA Observations
    • December Daily Observation Report:
      • MK Update
        • FRM Rotation overhaul was completed last week. Observing was renewed on January 9th. High frequency pointing run to be done soon.
        • USNO appreciates the continued use of S/X, observations have been good quality.
      • G& H Codes:
        • Andy: Reviewed 2017 codes. Scans causing G-codes (fringe amplitude is less than half of the average) are due to 4th channel on S-band. 2nd & 3rd channels are already dropped, but starting in March and April, 4th got words.
        • H-codes: Lower p-cal amplitude in 5th & 6th channel in MK. NRAO: ACTION we could increase amplitude across the whole band. We will investigate this.
    • December Post-Monthly Report Review:
      • USNO: This looks fine, time allocation & time spent calculations were explained.
  • Open issues
    • C-band Testing
      • USNO update: Spoke with Goddard in regards to moving forward with C-band observations. Goddard will look into incorporating C-band into CalcSOLVE, using the data provided by USNO.
      • The observation showed MK had no p-cal present. ACTION - COMPLETE: NRAO provided data to USNO.
        • USNO: This was useful. Had to adjust software parameters to find them in general observations. Issue resolved.
    • SC Update & Fiber
      • Operational Update: Power and phone communications are stable and running. No connectivity to the network yet, though (ETA later than January). An inspection team is being arranged for travel this month.
      • Fiber Update: There may be funding for infrastructure improvements to increase robustness against future natural disasters. This should include preparation for a fiber link that can be expandable to higher (10 GBPS) in the future but would start at a much lower rate (~20 MBPS). Near-term could be increased to 200 MBPS, USNO confirms this would be more than enough for dailies transmission.
    • Government Shutdown: Analysis group may have staff on-hand, as essential. Likely Megan or Chris in this case. For Correlator: there is an expectation that there will be staff, too. NRAO has internal funding to run for 2 weeks, at which point only essential staff will then be on but will include USNO observations.
  • Next meeting on February 8th
