  1. Project news/updates
  2. Board Communications
    • Discussion of Report Response and new Board Charges.
      • In order to allow time for the preparation of a response from the Project, it would be very much appreciated if the ASAC’s report for the Board’s November 2008 meeting could be made available by no later than October 30th and that for the first meeting of 2009 by March 2nd.
      • Continuing Charges:
        • 1) ASAC should continue to monitor and assess the readiness of ALMA software, in particular to review the outcome of software CDR number 6 and the ongoing work on detailing the software requirements for Early Science. These topics should be covered in the ASAC’s written report for the Board’s November 2008 meeting.
        • 2) ASAC should continue to review AIV/CSV activities and to recommend necessary and desirable changes. Any significant new issues in this area should also be included in thereport for the November 2008 meeting, but the Board expects a more detailed examination of these topics after the ASAC meeting in Chile in early 2009.
        • 3) The ALMA Board has charged the Project to draw up a long-term ALMA Development Plan in consultation with the international astronomy community. The plan should set out the scientific context for transformational science with ALMA in the next two decades, in the era of for example JWST, ELTs and SKA, and recommend developments necessary to achieve this vision. The ALMA Board views this plan as having a high strategic priority, and is coordinating its development across the entire ALMA partnership. The process of generating the ALMA Development Plan should be led by the JAO Project Scientist and the ASAC (with support from the Executives). The first stage will involve an examination of the scientific drivers by a team of astronomers, chosen to be representative of the broad astronomy community that is expected to use ALMA. It is therefore important that the proposed team include people with a broad perspective and expertise at wavelengths outside the range that will be observed by ALMA as well as people with experience of mm-wave interferometry and instrumental development. This team should take time to work with the community, e.g. by sounding their own 'networks' and holding local discussions, before making a first-order draft of potential long term developments, grouping them in high, medium and low scientific priority, and identifying the ones which require long-lead technical developments. The ASAC should review and comment on the report (again with members taking soundings through their networks) before submitting it to the Board. The Board would like to receive a progress report on this at its November 2008 meeting and, if possible, the full report by March 2009. The Board suggests that it would not be appropriate to hold a large community workshop devoted to this topic, but recommends that discussion sessions be planned as part of other workshops (e.g. at one of the annual ALMA-oriented science workshops, or at more general meetings on future astronomical facilities). It is anticipated that a larger-scale activity will follow after the start of Early Science.
      • Further Charges (to be confirmed at the Board’s June 2008 meeting):
        • 4) The ASAC should review the plans for provision of ALMA Regional Centers and report to the Board’s March 2009 meeting.
        • 5) Noting that 2009 is the International year of Astronomy, the ASAC should examine the Project’s activities in the area of outreach, both to the general public and to the astronomical community, and make suggestions as to how they and the ALMA Project could enhance these activities.
    • Dates Fall 2008 meeting is 28-29 September in Charlottesville--please enter a date for Spring meeting preference.
  3. Science IPT Report (Hills, Wootten, Testi, Morita)
    • Band 10 Report Atmosphere at 350 microns with lines The atmospheric transmission during best octile (stringency = 8) conditions at Chajnantor over the ALMA Band 10 window (787-950 GHz) is shown. Some important lines mentioned in the ASAC Enhancement report (Sept 2001) on Band 10 are flagged. Additionally, the ASAC mentioned the scientific utility of this window for Redshifted [C II] emission and also for dust emission . Redshifted [C II] can, of course, cover this band for z=1 - 1.4, a critical period in the evolution of galaxies toward their present form. The band is clearest in its center, of course, which makes that the best frequency locale for dust measurements. Please see Attachment at bottom of agenda
