NOAO Standard Observing Programs


NOAO is operated by the Association of Universities for Research in Astronomy (AURA), Inc. under cooperative agreement with the National Science Foundation


[ Proposal Information ] [ NOAO Proposal Form ]


Observing time for nighttime programs at the National Optical Astronomy Observatories is allocated via peer review twice a year. The facilities include the Cerro Tololo Inter-American Observatory, the Kitt Peak National Observatory, the U.S. share of the Gemini Observatories, and community access time at the MMT and HET Observatories. Time on all these facilities will be split with the NOAO Survey Program. Proposals are due Sept. 30 for the February-July observing period and March 31 for the August-January observing period. Procedures and forms for applying for telescope time can be obtained at http://www.noao.edu/noaoprop/noaoprop.html.


Who Can Apply for Telescope Time?

Applications for telescope time at NOAO nighttime facilities are welcome from all astronomers and students.

Applications from astronomers and students who work at non-U.S. institutions must indicate why the project cannot be done using other facilities available to the investigators and why U.S. national facilities are needed.


Criteria for the Evaluation of Telescope Proposals

Telescope time at NOAO facilities will be awarded on the basis of scientific merit.

The criteria for evaluating scientific merit of proposals for time on NOAO nighttime facilities are:

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.


Proposals from Graduate Students

A graduate student applying for time as a principal investigator must have her/his faculty advisor send a letter citing the graduate student's qualifications to complete an observational program and, if the program is a thesis, how this particular observing proposal fits into the overall thesis plans. The letter should describe any other telescope time being used as part of the thesis, and how many additional runs on what telescopes will be required to finish the thesis. This letter must be sent by the faculty advisor to noaoprop-letter@noao.edu before the proposal deadline.

If a graduate student is to be responsible for the observing on any program, whether that student is the principal investigator or not, a letter must be submitted from the thesis advisor stating that the student has sufficient experience and competence to carry out the observations.

At KPNO, graduate student thesis work is supported on all but the 4-m and 3.5-m telescopes through an implicit commitment for continuity of observing time once the original program has been granted time. On the larger telescopes, proposals for thesis observations must compete on an equal footing with all other proposals.


Proposals for Long Term Status

NOAO will accept proposals on any of its nighttime telescopes for scientific programs that extend beyond a single semester. Long-term status may be granted to proposals for which a scientific result 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 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.


Proposals for the 3.5-m WIYN Telescope

NOAO accepts proposals from the astronomical community for time on the 3.5-m WIYN telescope on Kitt Peak. NOAO is allocated 40% of WIYN telescope time by the WIYN (Wisconsin, Indiana, Yale, NOAO) Consortium; roughly 9-12 nights per month are available. Approved WIYN programs will be scheduled in two modes: classical mode, in which PI's are assigned specific nights, and queue mode, in which observations are obtained by the WIYN Queue Program staff. Assignment to the classical or queue mode will be made after proposals are reviewed by the TAC and by NOAO. Proposals for time on the WIYN telescope should be submitted on the standard NOAO form and by the normal proposal deadlines.

Proposals for small amounts of time (less than 2 hours) on the WIYN telescope may be submitted as well. Proposals for observations from the WIYN 2-hour queue should be submitted on the standard NOAO form and by the normal deadlines, but the scientific justification is limited to 1/2 page. Proposals for the WIYN 2-hour queue are reviewed internally and assigned a priority for observations.


Proposals to Observe Targets of Opportunity

NOAO encourages proposals for observations of targets of opportunity on its nighttime telescopes. Target of Opportunity (TOO) proposals may be of different types. If the targets occur unpredictably but frequently (e.g.novae, gamma ray bursts), investigators should prepare a standard proposal to be reviewed by the TAC. If the scientific merit of the proposal is high, CTIO or KPNO will agree to make available a limited amount of telescope time to the investigator should an appropriate event occur during the semester. Normally scheduled observers who are displaced by a Target of Opportunity may be compensated with additional telescope time at the discretion of the site Director.

When events which are genuinely rare and of major astronomical significance (e.g. a supernova in a local group galaxy) occur, interested investigators should immediately contact the appropriate site Director by fax or email. Special arrangements may be made by the Director to obtain critical observations. For CTIO send such requests to ctio@noao.edu, and for KPNO send requests to kpno@noao.edu.

Finally, investigators often submit short requests for data of particular objects which exhibit phenomena of interest (e.g. a Be star in outburst). A notification system is available to alert scheduled observers to unusual events for which small amounts of data may be useful. Such data may be obtained at the discretion of the scheduled observer.
