NSF's NOIRLab Call for Proposals: Semester 2021A

Call for Standard Proposals: Semester 2021A 

This Call for Proposals 2021A (CfP21A) covers the observing time period from 1 February 2021 – 31 July 2021.  Please read this document carefully, as the global COVID-19 pandemic has affected some telescope operations and schedules.

Proposal Deadline: 30 September 2020 at 11:59 pm Mountain Standard Time (MST). This document is also available as a downloadable PDF file attached at the end of this document.

1. General Information on NSF's NOIRLab Observing Proposals

Proposals for standard observing programs at all ground-based facilities coordinated by the NSF's NOIRLab, 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 2021A semester, the deadline is:

Standard Programs: Deadline is 30 September 2020 at 11:59pm MST (=Tucson time)  for the 1 February 2021 – 31 July 2021 observing period (2021A)
This Call is for Standard Observing propsoals only, but below we give a short description of the different NSF's NOIRLab 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 certainly considered. Standard programs are judged by one of eight 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, the NSF OIRLab 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.
NSF's NOIRLab 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 NSF NOIRLab-operated 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.
No Survey Proposals are being accepted as part of this Semester 2021A Call for 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
No Gemini LP proposals are being accepted as part of this Semster 2021A Call for Proposals.
Who can apply? Applications for telescope time at NSF NOIRLab 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 the NSF NOIRLab. 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 NSF NOIRLab 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.  This form can be found at:  https://www.noao.edu/noaoprop/thesis/
Criteria for the evaluation of telescope proposals to NSF NOIRLab facilities will be based on scientific merit. The criteria for evaluating scientific merit of proposals for time on NSF NOIRLab 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.
The NSF's NOIRLab is committed to maximizing the accessibility of astronomy to all qualified proposers. Many of the telescopes available through NSF's NOIRLab 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 2021A Proposals

The 2021A Call for Proposals covers proposals for observing programs at all ground-based facilities on which the NSF NOIRLab manages open-access observing time. Observing proposals for all telescopes, other than Gemini, must be submitted using the NSF NOIRLab Proposal Form, which is found at
An NSF NOIRLab 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  should be prepared to fund their own travel for their observing trips.  The  NSF NOIRLab will support graduate students traveling for observations that are part of their PhD thesis work.
AAT Proposals: The Australian Astronomical Observatory (AAO) and NSF NOIRLab/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 2020B, five classically-scheduled nights on the Anglo-Australian Telescope will be available to the NSF NOIRLab community. All AAT facility instruments are available.
Proposals for this time should be submitted through the NSF NOIRLab proposal form. The proposals will be reviewed by the NSF NOIRLab 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 2020 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.

3. News and Updates for Semester 2021A

The following updatess to instrumentation and or observing time at all facilities available through NSF's NOIRLab are noted here to alert investigators preparing proposals.

3.1 NNEXPLORE in 2021A: Time Available on the CTIO 1.5m with CHIRON and MINERVA-Australis.  Note: No New WIYN Proposals Solicited for Semester 2021A

The WIYN 3.5m telescope (along with all telescopes on Kitt Peak) has been closed since mid-March 2020 due to the COVID-19 pandemic and, at this time, there is no scheduled date for re-opening.  Due to this closure and its impact on Semester 2020A (1 February 2020 - 31 July 2020), as well as continuing impact on Semester 2020B (which began on 1 August 2020), WIYN is not soliciting new proposals for semester 2021A.  Those PIs with approved NEID programs for Semester 2020A will remain in the NEID queue for Semester 2021A.  At this point, there is no WIYN/NEID schedule for Semester 2020B and all 2020B proposals are being held in reserve by WIYN in order to prepare a schedule when the observatory reopens.  If you have questions about WIYN/NEID please contact us (vsmith@noao.edu, Jayadev.Rajagopal@gmail.com).
The other opportunities for NNEXPLORE continue; the CTIO/SMARTS 1.5m with the precision radial-velocity spectrometer CHIRON is available, with 300 hours (equivalent to 30 nights of service observing) of NNEXPLORE time.
New:  As part of the NNEXPLORE program, NASA entered in a partnership with the MINERVA-Australis consortium starting in 2020B.  That agreement continues in Semester 2021A, with 300 hours of observing time open to NNEXPLORE proposals.  MINERVA-Australis is a dedicated exoplanet observatory operated by the University of Southern Queensland (USQ) in Queensland, Australia. The facility is located at USQ's Mt. Kent Observatory, and saw first light in quarter two 2018; commissioning of the facility was completed in mid-2019.  MINERVA-Australis currently consists of 5 (0.7m) PlaneWave CDK700 telescopes; these telescopes have two ports, allowing each to be used for either spectroscopic or photometric observations.   A summary of the facility and its capabilities can be found in the commissioning paper by Addison et al. 2019 (https://ui.adsabs.harvard.edu/abs/2019PASP..131k5003A).  The photometric channel is capable of milli-magnitude precision and currently, the light from four telescopes can be combined onto one R=75,000 echelle spectrograph for radial velocity precisions of 1 -10 m/s depending on the target brightness and how many telescopes are combined.  

3.2 Gemini North and South

The Gemini Observatory has released a Call for Proposals for 2021A at:

The Gemini Call contains all of the information necessary to submit a Gemini proposal.  We suggest strongly that you also read the Gemini CfP if you are 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.

Potential Gemini-N ALTAIR users, note that ALTAIR is not offered in semester 2021A.

Gemini-Subaru Exchange

Gemini and Subaru are continuing their time-exchange program. A minimum of 5 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).

3.3 Zwicky Transient Facility and ANTARES event brokering

The NSF MSIP-funded Zwicky Transient Facility (ZTF) is currently issuing public transient alerts. The two ZTF public surveys (https://www.ptf.caltech.edu/page/ztf_msip) 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 (https://www.ptf.caltech.edu/ztf).
For 2021A, the NSF NOIRLab 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 NSF NOIRLab 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)
The NSF NOIRLab is currently filtering ZTF alerts through the ANTARES event
 broker system (https://antares.noirlab.edu). For 2021A, ANTARES
 capabilities include positional and/or catalog-based filters with
 associated delta-magnitude thresholds, as well as more complex
 filters.  Proposers interested in employing these ANTARES
 capabilities within their programs during 2021A are encouraged to
 contact Dr. Tom Matheson (matheson@noao.edu) 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.

3.4 KPNO

Mayall 4-m

The Mayall 4-m telescope is currently in the midst of commissioning the Dark Energy Spectroscopic Instrument (DESI). No time will be available through the NSF NOIRLab TAC.


As noted in Section 3.1, due to the extended closure of the WIYN Observatory (since mid-March 2020) caused by the COVID-19 pandemic, no new WIYN 3.5m NNEXPLORE proposals are solicited for Semester 2021A.


New proposals are solicited for the 0.9m with HDI.

3.5 CTIO

Blanco 4-m

Note that as of the date of this Call, 1 September 2020, CTIO remains closed due to the COVID-19 pandemic, with no scheduled reopening date; however, proposals are being solicited for Semester 2021A.

Instruments available: In 2021A, CTIO will be offering the Dark Energy Camera (DECam) and the Cerro Tololo Ohio State Multi-Object Spectrograph (COSMOS).

Nights available in 2021A for new regular programs is approximately 63.

Five nights of AAT time are available as part of an observing time-swap between the CTIO Blanco and the AAT 3.9m.

In the case of Blanco proposals from Semester 2020A that were approved but not executed due to the COVID-19 closure, PIs may resubmit their proposals and these will be routed to the same TAC panels.


Note that as of the date of this Call, SOAR remains closed due to the COVID-19 pandemic, with no scheduled reopening date; however, new proposals are solicitied for Semester 2021A, with approximately 35 nights available for new programs.

PIs of approved 2020A SOAR programs that were not completed may resubmit their proposals, which will then be sent to the same TAC panels.

The SOAR website is located at:


Instruments: All instruments that were available in the previous semester, including TripleSpec 4.1, are currently available. See the Facilities Table in Sections 4.1 and 4.2 below for a list with links.

Queue scheduling: For semester 2021A, SOAR will continue to offer queue time through the AEON network (http://www.ctio.noao.edu/soar/content/soar-aeon-home-page). Because we have a stable operation, we can now confidently support proposals that require the flexibility the AEON queue offers, in particular programs requiring small amounts of time spread over the semester, or where targets are not entirely predictable. AEON remains the recommended choice for programs with a large number of targets distributed over the sky, as well as those where monthly or bi-weekly cadences are required. We cannot generally support higher cadences (e.g., weekly) unless demand increases sufficiently; exceptions may be possible where the higher cadence is only required for a portion of the semester. Note that we can and do support observations of solar system objects using non-sidereal tracking.

At present, we can only commit to supporting the Goodman spectrograph in 2021A, however will be able to support both red and blue cameras and additional configurations where demand warrants. Specifically, we would add the blue camera if demand warrants, along with additional blue or high-resolution configurations for either or both cameras.

Time is allocated based on TAC priority and the AEON queue is currently filled at 100%, so the expected fraction of clear time is the same as for classical observing. Investigators receiving time through all SOAR partners are eligible to participate; time continues to be allocated by the individual partners.
Please consult the AEON pages for further details and for contact information if you have questions the website doesn't answer.
Targets of Opportunity: SOAR support target of opportunity programs; for specifics of the policy see http://www.ctio.noao.edu/soar/content/targets-opportunity-overview.

SMARTS (1.5m with CHIRON and 0.9m with CFCCD)

Time on the small telescopes at CTIO will be available to NSF NOIRLab users in 2021A. The telescopes are operated by the SMARTS consortium with up to 15% of time available to the NSF NOIRLab community.

Note that time on the 1.3m is not avaialble in 2021A.
The SMARTS web site is http://www.astro.yale.edu/smarts/
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 2021A semester. As a result up to 24 nights will be available for allocation by the NSF NOIRLab TAC  For more information on the 0.9m, please contact Dr. Todd Henry at thenry@astro.gsu.edu.
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).  300 hours is available for the NNEXPLORE program, and  200 hours will be available for scheduling by the NOIR Lab TAC for non-NNEXPLORE programs. For more information on the 1.5m, please contact Dr. Todd Henry at thenry@astro.gsu.edu.

5. How to Acknowledge Use of NSF NOIRLab Facilities

There are a variety of credit lines which are appropriate for citing the use of data from one or more of the NOIR Lab facilities. Please acknowledge the proper observatories by using the appropriate credit line as discussed below.

NOIRLab generic press release

NSF's National Optical-Infrared Astronomy Research Laboratory (NOIRLab), the US center for ground-based optical-infrared astronomy, operates the international Gemini Observatory (a facility of NSF, NRC-Canada, ANID-Chile, MCTIC-Brazil, MINCyT-Argentina, and KASI-Republic of Korea), Kitt Peak National Observatory (KPNO ), Cerro Tololo Inter-American Observatory (CTIO), the Community Science and Data Center (CSDC), and the Vera C. Rubin Observatory. It is managed by the Association of Universities for Research in Astronomy (AURA) under a cooperative agreement with NSF and is headquartered in Tucson, Arizona. The astronomical community is honored to have the opportunity to conduct astronomical research on Iolkam Du’ag (Kitt Peak) in Arizona, on Maunakea in Hawaiʻi, and on Cerro Tololo and Cerro Pachón in Chile. We recognize and acknowledge the very significant cultural role and reverence that these sites have to the Tohono O’odham Nation, to the Native Hawaiian community, and to the local communities in Chile, respectively.

Observers should also note their NOIRLab proposal ID and observing dates in their publications either in a footnote, or in the observations section or acknowledgments sections of their papers.

Visitors are asked to add a Kitt Peak byline on the title page, as a footnote to the author, that reads:
Visiting Astronomer, Kitt Peak National Observatory, NOIRLab, which is operated by the Association of Universities for Research in Astronomy (AURA) under cooperative agreement with the National Science Foundation.
NOIRLab staff members are asked to add a footnote after their names on the title page that reads: Kitt Peak National Observatory, NOIRLab, which is operated by the Association of Universities for Research in Astronomy (AURA) under cooperative agreement with the National Science Foundation.
In addition to the Kitt Peak credit line, Case Western Reserve University has requested that a special acknowledgement be included on papers resulting from observations obtained with the Burrell Schmidt telescope:
Observations made with the Burrell Schmidt of the Warner and Swasey Observatory, Case Western Reserve University.
In addition to the Kitt Peak Credit line, the WIYN Observatory Corporation has requested that the following acknowledgement be included in any paper using WIYN data. The acknowledgement should be included as a footnote on the title page. The WIYN Board also encourages the mention of WIYN in the title or abstract of the paper:
