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.
We invite proposals for the use of the Arecibo 305-m telescope for the Thursday, March 2, 2017 (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, 2017. This call does not include proposals for use of the HF Facility for ionospheric modification.
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 and Frequently Asked Questions (FAQ) on the new policies and procedures can be found here. Note that the FAQ will be updated as questions come in, so please check back.
Please note that the NSF is yet to decide on the operations model for the Observatory beyond the end of March 2018. This may affect proposals requesting time in the second semester at this deadline.
We regret that we are unable to host on-site observers working for institutions in China. Observers from this country are welcome to apply for time as remote or in-absentia observers, but should meet the criteria for these observing modes.
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.
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 (email@example.com).
