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:
The 2020A 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, 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.
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 2020A, five classically-scheduled nights on the Anglo-Australian Telescope will be available to the NOAO community. All AAT facility instruments are available.
An additonal 5 nights are available to the community through NN-EXPLORE (see Section 3.1) on the precision radial-velocity spectrograph, Veloce, for exoplanet research.
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 2019 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 2020A
The following updatess to instrumentation at all facilities available through NOAO are noted here to alert investigators preparing proposals.
3.1 NN-EXPLORE in 2020A: NEID on WIYN, the CTIO 1.5m with CHIRON, and AAT+Veloce Time
The NASA/NSF Exoplanet Exploration Program (NN-EXPLORE) is seeking proposals to use NEID, a new cutting edge high-precision spectrograph at WIYN designed for radial velocity measurements of exoplanet host stars. NEID is designed with a goal of achieving 27 cm/s precision per data point, providing the US exoplanet community with high-precision radial velocity measurements appropriate for studying Earth and super-Earth mass planets orbiting bright host stars over a wide range of spectral type. Other investigations that hinge on extreme RV precision can also make good use of NEID. NEID is scheduled to begin commissioning at WIYN in November 2019. Proposers can request NEID in "shared risk" mode for programs that can be executed in 2020A. For more information on NEID, see http://ast.noao.edu/observing/wiyn-neid
New: Five nights in 2020A are available on the AAT 3.9m telescope with the precision radial-velocity spectrometer Veloce as part of NN-EXPLORE.
The other opportunities for NN-EXPLORE continue: WIYN with its full instrument complement, along with 400 hours (the equivalent of 40 nights) on the CTIO/SMARTS 1.5m with the precision radial-velocity spectrometer CHIRON.
3.2 Gemini North and South
The Gemini Observatory has released a Call for Proposals for 2020A 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 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).
3.3 Zwicky Transient Facility and shared-risk 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 2020A, 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 is currently filtering ZTF alerts through the ANTARES event
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 2020A are encouraged to
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.
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 NOAO TAC.
As in previous semesters, priority at the WIYN-3.5m in 2020A will be given to qualifying proposals under the NN-EXPLORE program. More information on the NASA Guest Observer program can be found at http://ast.noao.edu/observing/wiyn-exoplanets-2020a. Commissioning of the new high-precision spectrometer, NEID, is expected to take place in 2019B. Proposers can request NEID in "shared risk" mode for programs that can be executed late in 2020A. For detailed information about how to propose for NEID please see http://ast.noao.edu/observing/wiyn-neid .
Other 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 2019B should contact the PI (Matthew Bershady) at email@example.com 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 (http://www.wiyn.org/Observe/wiynproposalinfo.html) to ensure all the required information is submitted on your proposal.
Remote Observing: KPNO offers remote observing for selected programs on WIYN in 2019B. If you are interested in this opportunity, please see the requirements for observing remotely at http://www.wiyn.org/Observe/wiynremote.html. 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.
Instruments avasilable: In 2020A, CTIO will be offering the Dark Energy Camera (DECam) and the Cerro Tololo Ohio State Multi-Object Spectrograph (COSMOS).
Nights available in 2020A for new regular programs: Approximately 90.
The SOAR website is located at:
Several special opportunities are available for SOAR in 2020A - interested parties whoo need more information should contact support staff.
TSpec availability: The TripleSpec instrument (ex-ARCOIRIS, re-baptized TripleSpec 4.1) was commissioned in 2019. People interested in proposing can do so using performance information from the Blanco telescope (http://www.ctio.noao.edu/noao/content/Arcoiris) until the SOAR web pages are fully updated. Contact Sean Points for further information.
All other instruments that were available in the previous semester are currently available: see the Facilities Table in Section 4.1 below.
Queue scheduling opportunity: Starting in 2019B, SOAR has been operating a fraction of its nights in queue mode. For 2019B, we are only supporting observations with the Goodman spectrograph, red camera, and 400 l/mm and 2100 l/mm gratings, in specific configurations. For 2020A we will offer additional configurations, based in part on user demand. We expect these to include the blue camera and one or two of the intermediate-resolution gratings. If your proposed configuration will not be supported, but your program is feasible as a classical program, it will be considered accordingly.
Since the queue nights are rather sparsely scheduled (cadence of a night every 7 to 15 days, depending on demand), programs that require a higher cadence cannot be currently supported.
For further details, including how to express interest in participation, please see the SOAR web pages or contact Cesar Briceno.
Time on the small telescopes at CTIO will be available to NOAO users in 2020A via the usual proposal process. The telescopes are operated by the SMARTS consortium with up to 15% of time available to the NOAO community.
Note that time on the 1.3m is not avaialble in 2020A.
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 2020A semester. As a result up to 24 nights will be available for allocation by the NOAO TAC For more information on the 0.9m, please contact Dr. Todd Henry at firstname.lastname@example.org.
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). 400 hours is available for the NN-EXPLORE program, and 270 hours 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 email@example.com.
