Arecibo Call for Proposals

Deadline: Thursday, March 1, 2018

AO - Call for Proposals 2018

We invite proposals for the use of the Arecibo 305-m telescope for the Thursday, March 1, 2018 (17:00 AST, 21:00 UTC) , deadline. These requests should be for telescope usage within the six-month (or in some cases one-year) period beginning July 1, 2018. This call does not include proposals for use of the HF Facility for ionospheric modification (please see the HF call).

Arecibo telescope proposal deadlines fall on the first Thursday of March and September each year. The corresponding scheduling terms are July 1 – December 31 and January 1 – June 30.

Proposals should be prepared under the procedures detailed in our guidelines. Please note that these were substantially revised in July 2016, a summary of the more major changes and the rationale behind them can be found here, while Frequently Asked Questions (FAQ) on the new policies and procedures can be found here. The FAQ will be updated as questions come in, so please check back.

Please note that the Observatory will be transitioning to new management, to be in place by April 1, 2018. We are aiming for a July 1 start date as normal for the observing semester, provided no unexpected issues arise during the transition process.

We regret that, due to Congressional restrictions on the use of NASA funds, we are unable to host on-site observers working for institutions in China. Observers from China are welcome to apply for time as remote or in-absentia observers, but should meet the criteria for these observing modes.

After submitting their cover sheet, PIs of proposals with continuing status should upload their report to ASAC via the proposal system as if it were the body of the proposal.

Technical information for Radio Astronomy proposals for this deadline. We remind users about the online Proposal and Observation Preparation Tools, which include tools to compute LST rise and set times for sources and to calculate the dates when sources will be visible at nighttime.

Technical information for Space and Atmospheric Science proposals for this deadline.

Other information of interest to our users can be found on the Astronomy, Planetary Sciences and Space & Atmospheric Sciences pages.

Proposals must be submitted using the web-form cover sheet. You should upload a PDF file containing the main body of your proposal via the proposal website. Please email any questions about this call for proposals to Robert Minchin (
