Discussion Items

  1. NAASC (Jewell)
  • Long Baseline Campaign (LBC) LBC is currently finishing up
    • Moving antennas into more compact configurations
    • ES Observing will resume at the end of this month
  • NA ALMA Antenna Review
    • Panel met on 27-29 October in Charlottesville
      • Chaired by David Woody with 10 other members from other executives and independent experts
    • Determined three good possibilities for the surface accuracy (vs temperature) issues:
      • Squeezing of the receiver cabin by the (cold) yoke
      • Azimuthal thermal gradients in the receiver cabin
      • Quadrupod asymmetry
    • The panel suggested several follow-up actions to narrow these down.
    • NRAO is working on a project plan and will engage Vertex and JAO in the program.
  • ALMA Board Meeting
    • Operation’s Readiness Review Deferred until week of 27 April 2015
    • Long Baseline Campaign SV data will be released to the public in February. The JAO staff plans to write a 4/5 papers summarizing at a high level the results of the LBC which will be submitted shortly thereafter, in accordance with procedure. The Board discussed and noted this plan.
    • The ASAC report recommendations were accepted by the Board.
  • UC / ANASAC Report received, response is being prepared.
  • The NAASC has two positions advertised – an astronomer (tenure track) and a scientist track (one or more positions available).
  1. Program Scientist (Wootten)
  2. Science Status (Lonsdale)
    • ES begins again Dec2 in most compact configuration (C34-1). Another ES hiatus Feb/Mar for annual software/hardware upgrades.
    • ALMA Status Report was posted to SP on Nov 12, and broadcast to NA community
      • Includes configuration schedule, observing statistics, remaining observing pressure as function of LST, config & Band, EOC summary
    • PL-assisted data reduction is ongoing. Our goal is to get these to attending PIs before December
    • Cycle 3 planning:
      • Call/Deadline in Mar/Apr next year; panel meetings June in Japan; observing starts Oct1. 12mo cycle, so will be close to yearly cadence
      • Cycle 3 proto-capabilities (TBC): 36 antennas, longer baselines (frequency dependent), FDM polarization. Go/no-go decision on these will be made on Dec1. SG limitations will persist (5 tunings, 150ptg, 10deg limits per SG)
    • Support to JAO: E. Fomalont & A. Remijan (long term EOC support), T. Hunter/ C. Brogan/L. Perez (long term EOC support for long baseline campaign Oct/Nov); R. Simon/J. DiFrancesco /K. Sheth/D. Brisben (AoD support Dec/Jan).
    • NA Cycle 1&2 Data Reduction update (Nov17):
      • Cycle 1: 198 HP projects in total. 140 (70%) with some SBs finished, 127 (64%) with some data delivered; 64 (32%) completely delivered.
      • Cycle 2: Cycle 2 HP Projects: 354 projects in total. 113 (32%) with some SBs finished, 62 (18%) with some data delivered; 12 (3%) completely delivered.
  3. Astronomer Outreach
  4. Date of next meeting
    • 15 Jan 2015
    • Proposed dates for 2015 telecons: 15 Jan, 5 Mar, 7 May, 2 Jul, 3 Sep, 5 Nov. Comments please.
