NOAO  |  STScI  |  Chandra  |  Spitzer  |  Fermi

NOAO collaborates with NASA Space Observatories, the Hubble Space Telescope, Chandra, Spitzer, and Fermi, to provide investigators with complementary ground-based observations in support of their programs. Investigators can obtain time on facilities available through NOAO through proposals for Fermi Cycle 10, HST Cycle 25, and Chandra Cycle 19 programs. This collaboration allows proposers to avoid the double jeopardy inherent in having to pass through two separate TAC processes, and provides access to facilities essential to obtaining complementary ground-based O/IR data without regard to institutional affiliation. The time awarded through this process will not be extended or augmented to account for losses due to bad weather. In such cases, investigators may wish to submit a new proposal to the NOAO TAC.

Fermi Cycle 10

The Fermi Gamma-ray Space Telescope (formerly GLAST) was launched Jun 11, 2008. In recognition of the importance of optical observations enabled by NOAO to the scientific exploration by Fermi, the Fermi-NOAO cooperative arrangement commits observing time on NOAO telescopes for observations in support of Fermi related science programs.

Through proposals submitted via the Fermi Guest Investigator (GI) Cycle 10 program, proposers can obtain access to the Fermi survey data product, research funding, and allocations of observing time on most of the facilities to which NOAO provides access. Please note that proposers desiring Target of Opportunity (ToO) observations on NOAO facilities must also submit a complete proposal via the NOAO proposal system. Successful proposals for NOAO observing time submitted via the Fermi GI program will be scheduled during NOAO observing semesters 2018A and 2018B. Successful proposals submitted to the NOAO proposal process could be implemented in semester 2017B as well in some cases. The details of this opportunity are slightly different than from previous arrangements with NASA space observatories.

NOAO, ToO, and Survey Program proposals requesting Fermi funding must be submitted by the proposers, using appropriate forms and processes, to both NOAO and the Fermi Guest Investigator (GI) program in order to be considered for NOAO observing time and funding by NASA/Fermi. The deadline for Fermi GI program Cycle 10 proposals is February 24, 2017, 4:30pm EST. The next deadline for standard NOAO proposals (and therefore for ToO proposals to NOAO) is March 31, 2017.

Proposers interested in NOAO observing time related to their Fermi proposal, but not requiring Survey or ToO observations, need only submit one proposal to the Fermi GI program (no NOAO proposal required).

Detailed information regarding the Fermi GI (Guest Investigator) program can be found at:

HST Cycle 25

Investigators who apply for Cycle 25 observations with the Hubble Space Telescope can also apply for time at the listed NOAO facilities in the same proposal, with a cap of approved time at 5% of the total available NOAO time. Check the announcement for Cycle 25 proposals at . The deadline for Cycle 25 Phase I proposals is April 7, 2017 8:00 pm EDT. Time is available in the 2018A and 2018B semesters only. Not all instruments and telescopes currently available at NOAO will be available in future semesters.

Chandra Cycle 19 GO Proposals

Investigators applying for Chandra Cycle 19 programs may also request time at the listed NOAO facilities in the same proposal, with a cap of approved time at 5% of the total available NOAO time. The key criterion in the award of NOAO time is that the x-ray and optical data form a coherent database such that both sets of data are required to meet the scientific goals of the proposal. Proposals are due March 15, 2017 6:00 p.m. EDT, and investigators may obtain further information at the Chandra website: Chandra Cycle 19 will be of one year duration, and NOAO allocations for approved Chandra programs will be scheduled in the 2018A and 2018B semesters.

Spitzer Cycle 7 Programs

No joint Spitzer-NOAO observing proposals has been available in Spitzer Cycle 7 or later.

Instruments and Telescopes Available

Only those instruments listed in the active NOAO Call for Proposals will be available for time through this program.

Five percent of the available time roughly corresponds to:
