Proposal Submission Information

The Arizona Radio Observatory (ARO) solicits observing proposals for the 10-meter Submillimeter Telescope (SMT) located on Mount Graham, Arizona, and the new ALMA Prototype 12-meter Telescope (12m) located on Kitt Peak, Arizona, for the period February 15, 2016 - June 15, 2016.

Graduate student participation is especially encouraged.

The SMT currently supports a dual-polarization 1 mm (211-275 GHz) receiver with ALMA Band 6 sideband-separating (SBS) mixers, a dual-polarization 0.8 mm (320-370 GHz) receiver, a dual-polarization 0.7 mm (420-500 GHz) SIS receiver with SBS mixers, a 0.4 mm (602-720 GHz) dual-polarization receiver with ALMA Band 9 mixers, and a new Band 7 receiver with SBS mixers will be available in Spring 2016. The SMT control system supports both dual-polarization ("2 IF mode") and dual-polarization, dual-sideband observations ("4 IF mode"), as well as OTF mapping.

The new 12m will support an ALMA Band 3 dual-polarization SBS receiver (84-116 GHz) for this season.

Remote observing is available. Observers who plan to observe remotely must supply fixed IP address(es) of the computer(s) that will be used during observing on their Proposal Summary Sheet.

Information about Remote Observing can be viewed at:

Proposal candidates should consult the ARO website,, for technical specifications.

Updated Proposal Summary Sheet form templates can be downloaded here:

SMT Proposal Summary Sheet (PDF fillable format)

12M Proposal Summary Sheet (PDF fillable format)

Proposal candidates are required to list on the Proposal Summary Sheet their requested observing blocks (LST ranges), dates on which they are not available to observe, and dates in which sources in those observing blocks are within the Sun-avoidance zone (44 degrees at the SMT).

Proposal candidates are also encouraged to submit up to two pages of scientific justification (including figures) with their Proposal Summary Sheet.

Proposals will be reviewed by the ARO TAC. Scheduling of successful proposals will be done according to availability of the receivers requested.

The telescopes are expected to be available to the general astronomical community for a minimum of 10 percent of the scheduled time. Graduate student participation is especially encouraged regardless of institutional affiliation. Institutions (or individuals) that wish to acquire longer commitments of time should contact Buell Jannuzi, Director of Steward Observatory:

Deadline for proposals is: To Be Announce
