Deadline for proposals is 23:59 MST on September 20, 2022.

Email the proposal to:

The Arizona Radio Observatory (ARO) solicits proposals for the:

  • UArizona ARO Submillimeter Telescope (SMT) located on Mount Graham, Arizona, for the period October 15, 2022 - February 15, 2023.
  • UArizona ARO 12-meter Telescope (12M) located on Kitt Peak, Arizona for the period November 15, 2022 – February 15, 2023.

Proposers are requested to fill out both pages of the cover sheet and combine into one single PDF file the following:

  1. Proposal Cover Sheet (two pages - must use the latest 2 page cover sheet found here): 
  2. Science justification (no more than two pages)
  3. Technical justification (no more than one page)
  4. Update on analysis/publication of past time allocations (no more than one page)

Note: references do not count against your page limit and may be included as a separate additional page.

The combined PDF should follow the following naming convention:


where the LastName and FirstInitial are of the PI of the proposal, Semester = 2022b, 2023a, etc. with a = first semester proposal call of the calendar year and b = second semester of the calendar year. The _1, _2, etc. increases for multiple proposals from the same PI.

The UArizona SMT currently supports dual-polarization sideband-separating observations at 1mm (210 – 280 GHz SIS) and dual-polarization double sideband observations at 0.8mm (325 – 370 GHz SIS). The UArizona 12M telescope currently supports dual-polarization sideband-separating observations at 4mm (69 – 90 GHz HEMT), 3mm (84 – 116 GHz SIS), 2mm (129 – 180 GHz SIS), and 1mm (210 – 275 GHz SIS). Both telescope control systems support dual-polarization position-switched, beam-switched, and OTF observations. Proposal candidates should consult the ARO Equipment Summary and Status sheet for additional technical specifications and experimental capabilities: Equipment Summary and Status

ARO facilities are currently restricted to remote observing. Observers must supply fixed IP address(es) of the computer(s) that will be used during observing on their Proposal Cover Sheet. For further information about remote observing and other operational questions, please contact the ARO Software Engineer, Natalie Gandilo.

Proposals will be reviewed by the ARO TAC and scheduling recommendations are made to the Director of Steward Observatory. Scheduling of recommended proposals will be done according to availability of the receivers requested with a minimum of 10% of the scheduled time to be available to the general astronomical community. Institutions (or individuals) outside of the State of Arizona that wish to acquire longer commitments of time through a limited duration agreement with The University of Arizona should contact the Director, Buell Jannuzi.
