NOAO Call for Proposals: Semester 2019A

Call for Standard Proposals: Semester 2019A  

This document covers the observing time period from 1 February 2019 – 31 July 2019.

Proposal Deadline: 1 October 2018 at 11:59 pm Mountain Standard Time. This document is also available as a downloadable PDF file:

1. General Information on NOAO Observing Proposals

Proposals for standard observing programs at all ground-based facilities coordinated by NOAO, which include US time on the telescopes of Gemini, CTIO, and KPNO, as well as community-access time with private observatories, can be submitted twice per year. For the 2019A semester, the deadline is:

Standard Programs: 1 October 2018 at 11:59pm MST (=Tucson time) deadline for the 1 February 2019 – 31 July 2019 observing period (2019A)
This Call is for Standard Observing propsoals only, but below we give a short description of the different NOAO proposal types.
Standard Programs are traditional proposals for observing time allocated on a semester basis. Standard proposals generally request modest amounts of time, although requests for long runs are also considered. Standard programs are judged by one of seven TAC panels, each with five members plus a non-voting Chair. The Chairs present the proposal rankings made by the panel members at the meeting where the proposals are merged into a single ranked list.
Long Term Status for Standard Programs are for scientific programs that, by their design, need to extend beyond a single semester. Long-term status may be granted to a proposal for which the principal science goal of the proposal cannot be achieved without the full allocation of time. An investigator who wishes to request long-term status should include a summary of the request (e.g., "six nights per semester for four semesters") in the appropriate section of the proposal form.
If long-term status is granted, a progress report must be submitted each subsequent semester to inform the TAC that appropriate progress is being made. Progress reports should briefly summarize the scientific justification, provide a detailed discussion of progress to date, restate the number of observing runs still needed to complete the project, and give details needed for scheduling the proposal in the next semester.
Although the granting of long-term status by the TAC does carry with it a commitment for observing time in future semesters, NOAO reserves the right to terminate long-term status on the advice of the TAC if insufficient information concerning the progress of the project has been supplied by the Principal Investigator or in the event of telescope closures.
NOAO Survey Programs have been carried out in the past using the telescopes at KPNO and CTIO. Up to 20% of the observing time available through NOAO-opersated telescopes may be allocated to Survey Programs. 
Survey programs are judged by a dedicated Survey TAC panel, which uses a wider range of criteria than does the regular TAC. The scientific bar for acceptance of Survey programs is thus considerably higher than for Standard proposals.  
Gemini Large or Long Programs (LP) are those that require either significantly more time than a partner typically approves for a single program, or extend over 2 to 6 semesters, or both. The participating partners (US and Canada) will make up to 20% of their time at each telescope available for LPs. Gemini LPs are judged by a dedicated LP TAC, with representatives from the participating partners. Further information on LPs and the LP proposal process can be found at
Who can apply? Applications for telescope time at NOAO facilities are welcome from all astronomers and students. Applications from astronomers and students who are affiliated with non-US institutions should indicate why the project cannot be done using other facilities that might be available to the investigators and why US national facilities are needed. Proposals from graduate students who are conducting observations as part of their Ph.D. thesis work will have their travel and on-site expenses paid for by NOAO. Please select "Graduate student, and THIS proposal is part of thesis" ONLY if the requested observations are essential for the Graduate Thesis. For all other cases, please simply select "Graduate Student" (e.g. if the student is in fact working toward a thesis, but this proposal is not essential to that effort). Thesis Advisors should be aware that a Thesis Student Information Form should be completed and submitted within two business days after the proposal deadline. This form is required for the student to be considered for NOAO travel support. Lacking the Advisor's submission by the deadline, the proposal will be considered as any other non-thesis proposal, and travel support will not be granted.
Criteria for the evaluation of telescope proposals to NOAO facilities will be based on scientific merit. The criteria for evaluating scientific merit of proposals for time on NOAO facilities are:
  • The relevance and importance of the proposal within the area of specialization.
  • The relevance and importance of the proposal in the larger context of astronomical research.
  • The suitability of the experimental design to achieve the scientific goals (including sample size, required S/N, approach to deal with difficult data reduction problems, etc.).
  • The significance of the proposed observations for the completion of the project.
  • The likelihood that the researchers will complete the project and publish their results and the adequacy of the resources available to them in order to do this.
  • The broader impacts of the proposed research, for example, in education and public awareness of science.
In addition, the value of the proposed research to the educational and career development of the investigators may be considered in exceptional circumstances.
For CTIO proposals, preference may be given to proposals which can only be carried out in the southern hemisphere.
NOAO is committed to maximizing the accessibility of astronomy to all qualified proposers. Many of the telescopes available through NOAO support remote observing, and we are happy to discuss ways in which this mode can be employed to address specific issues of accessibility. To enquire about remote observing and other forms of access, and to request specific accommodation, please contact any of the following individuals:

2. Instructions for Submitting Semester 2019A Proposals

The 2019A Call for Proposals covers proposals for observing programs at all ground-based facilities on which NOAO manages open-access observing time. Observing proposals for all telescopes, other than Gemini and LBT, must be submitted using the NOAO Proposal Form, which is found at
The NOAO proposal can either be prepared and submitted completely online or a LaTeX template can be completed locally and submitted via a web upload.

Gemini Proposal Investigators who are applying for time on the Gemini telescopes must use Gemini Observatory's Phase I Tool (PIT) to prepare their observing proposals. The PIT is available from the Gemini Observatory at:

Classical observers using US time on the Gemini telescopes should be prepared to fund their own travel for their observing trips. NOAO encourages classical observing for the benefits that the on-site experience provides, and will attempt to fund, at least in part, the cost of travel for one Gemini classical observer per run. However, because of tight funding constraints, NOAO cannot guarantee such support. NOAO will continue to support graduate students traveling to Gemini for observations that are part of their PhD thesis work.
LBT Proposal Investigators who are applying for community time with the Large Binocular Telescope Observatory must use their version of the Phase I Tool (PIT) to prepare their observing proposals. The LBTO PIT is available from the LBT Observatory at
The text sections of LBTO PIT proposals will need to be attached as a PDF document. Please use the NOAO LBT Latex or Word template provided at our website to write your NOAO LBTO PIT proposal.
AAT Proposals: The Australian Astronomical Observatory (AAO) and NOAO/CTIO are continuing a time exchange arrangement, to allow our respective communities to maximize the scientific facilities and opportunities to which we have access. In 2019A, five classically-scheduled nights on the Anglo-Australian Telescope will be available to the NOAO community. All AAT facility instruments are available.
Proposals for this time should be submitted through the NOAO proposal form. The proposals will be reviewed by the NOAO TAC, and the successful proposals submitted to the AAO for scheduling. Note also that proposals for AAT time through the regular AAT open call, submitted by the AAO deadline of 15 September 2018 at 17:00 (AEDT) using the AAO form, are also encouraged by the AAO. These will be assessed only by the Australian Time Assignment Committee.

4. News and Updates for Semester 2019A

The following updatess to instrumentation at all facilities available through NOAO are noted here to alert investigators preparing proposals.

Gemini North and South

The Gemini Observatory has released a Call for Proposals for 2019A at:

The Gemini Call contains all of the information necessary to submit a Gemini proposal.  It is usggested that you read the Gemini CfP if youare requesting Gemini time.

Proposers requesting Gemini time must use the Gemini Phase-I Tool (PIT):


The Gemini Phase I Tool (PIT) will automatically add the time for the baseline partner calibrations to the total time requested for each target in the proposal.

Gemini-Subaru Exchange

Gemini and Subaru are continuing their time-exchange program. A desired minimum of five classically-scheduled nights will be available to the Gemini community, providing that there is sufficient demand from both sides of the exchange. Please see the Gemini call for proposals for more information. Proposers requesting Subaru time must use the Gemini Phase-I Tool (PIT).

Zwicky Transient Facility and shared-risk ANTARES event brokering

The NSF MSIP-funded Zwicky Transient Facility (ZTF) is currently planning to begin issuing public transient alerts sometime in advance of the start of the 2018B observing semester. The two ZTF public surveys 
( are (1) an all-sky survey with a three-night cadence and (2) a Galactic-plane survey with a nightly cadence. Both these surveys are expected to reach approximate point-source depths of r = 20.4 and g = 21.0. Further information can be found through the  ZTF project website
For 2019A, NOAO encourages submission of proposals for “target-of-opportunity” (ToO) follow-up observing triggered by ZTF alerts. Proposals should plan to use the current ToO policies and mechanisms for the facilities allocated through the NOAO TAC. More information about current ToO policies and procedures at available open-access facilities can be found here:
Gemini Target of Opportunity observing:
CTIO Target of Opportunity observing:
SOAR Target of Opportunity observing
Las Cumbres Observatory scheduling (including ToO)
NOAO plans to offer limited filtering of ZTF alerts through the ANTARES event broker system ( in a shared-risk/science-verification mode of operation. For 2018B, ANTARES capabilities are likely to be limited to positional and/or catalog-based filters with associated delta-magnitude thresholds. Proposers interested in employing these ANTARES capabilities within their programs during 2019A are encouraged to contact Dr. Tom Matheson ( in advance of the proposal deadline. Support for ANTARES science verification programs will be subject to availability of resources; depending on demand during this initial call, it is possible that only a subset of programs will be chosen for use with ANTARES.


Mayall 4-m

The Mayall 4-m telescope has been taken out of service for installation of the Dark Energy Spectroscopic Instrument (DESI). No time will be available through the NOAO TAC.


As was the case in the 2018B semester, priority at the WIYN-3.5m will be given to qualifying proposals under the NN-EXPLORE program. More information on the NASA Guest Observer program can be found at Due to the installation and commissioning of the NEID instrument, the number of nights available on WIYN will be significantly lower this semester. 


Instruments offered at WIYN include the upgraded ODI, with a 48'x40' focal plane. Other facility instruments on offer are HYDRA, the IFUs (SparsePak, HexPak, and GradPak), WHIRC (with or without WTTM), and the queue-operated speckle imager NESSI. Observers wishing to use Hexpak or Gradpak in 2019A should contact the PI (Matthew Bershady) at before submitting a proposal to use these IFUs.


Note to ODI proposers: the smaller Mosaic filters are no longer be available with ODI due to the full complement of permanently mounted, large ODI filters.  These include u’,g’,r’,i’,z’ and four narrowband filters (NB422, NB695, NB746 and H-alpha).


All WIYN proposers, please review the Proposal Information page ( to ensure all the required information is submitted on your proposal.


Remote Observing: KPNO offers remote observing for selected programs on WIYN in 2019A. If you are interested in this opportunity, please see the requirements for observing remotely at If you are requesting remote observing, please make a note of this in the "Scheduling constraints and non-usable dates" section that appears at the bottom of the first page of the NOAO proposal form and include any additional details in the "Technical Description" text of your observing run.


Blanco 4-m

Instruments avasilable: In 2019A, CTIO will be offering the Dark Energy Camera (DECam) and the Cerro Tololo Ohio State Multi-Object Spectrograph (COSMOS).

Nights available in 2019A: Approximately 98.


The SOAR website is located at:

There are some changes is what SOAR is offering during the next semesters; these are described below.

All instruments that were available in the previous semester are currently available.

  • The SOAR Integral Field Spectrograph (SIFS) continues to be offered in “campaign mode”, because calibrations and data reduction require direct support from Brazil. Its use will be restricted to 2 runs of 6 nights each (assuming sufficient demand). The NOAO share of this time, assuming all SOAR partners request time, would be 3.6 nights. Requests for NOAO time should be made through the TAC. See the SOAR website ( for details on the available configurations and on instrument performance. Interested users should not hesitate to apply for time; this is an instrument that is producing scientific results.

When in doubt, consult the SOAR webpages ()

Prospective users are reminded that:

  • SOAR does support target of opportunity proposals. To make life easier for all involved, include "ToO Proposal" in your proposal title. See for the overall SOAR ToO policy. The policy has been revised (again) for 2019A and B, to allow more interrupts to be allocated, and to separate support allocations for gravitational-wave-event follow-up. On a trial basis, SOAR will be scheduling a few nights in 2019A to provide compensation to observers who lose time to ToO observations. Compensation to individual observers (as opposed to NOAO or other partners in general) is not guaranteed, however.
  • SOAR supports allocations in half-night pieces, subject to scheduling constraints. Again, see the "Proposing for SOAR" page for a discussion.
  • Due to the limited response, SOAR is NOT supporting requests for service observing during 2019A.

Upcoming instrument commissioning and science verification. We currently expect to be performing science verification (SV) on both the STELES echelle spectrograph and TripleSpec 4.1 (ex-ARCOIRIS, transferred from Blanco), possibly as early as December. We will announce SV opportunities on the SOAR website; if you are interested in either instrument you can also contact the local instrument scientist (Andrei Tokovinin for STELES, Sean Points for TSPec 4.1). It is not possible to propose for either instrument for 2019A through the normal TAC process.


Time on the small telescopes at CTIO will be available to NOAO users in 2018A via the usual proposal process. The telescopes are operated by the SMARTS consortium with up to 15% of time available to the NOAO community.
The SMARTS web site is
The 0.9m + CFCCD is available in user mode only. It is being operated on a part time basis (operating on up to 60% of nights), during the 2018B semester. As a result up to 18 nights will be available for allocation by the NOAO TAC  For more information on the 0.9m, please contact Dr. Todd Henry at
The 1.3m + ANDICAM (dual channel optical/IR imager) is available in queue/service mode only. The 1.3-m telescope is used primarily for monitoring projects; thus, programs are scheduled in non-contiguous segments of an hour or less with a limit of three hours total within any given night. For inquiries about scheduling or 1.3m + ANDICAM observing capabilities, please contact the SMARTS 1.3m queue manager Bryndis Cruz at For any other inquiries about the 1.3m, please contact Charles Bailyn at
Non-sidereal tracking is no longer supported as service or queue observing. The only option for non-sidereal is user time on the 0.9m.
The 1.5m + CHIRON (fiber-fed cross-dispersed echelle).  350 hours is available for the NN-EXPLORE program, and we anticipate that ~100 hrs will be available for scheduling by the NOAO TAC for non-NN-EXPLORE programs. For more information on the 1.5m, please contact Dr. Todd Henry at
