ATNF Online Proposal Applications & Links

Welcome to OPAL, the Australia Telescope National Facility online proposal system.


The ATNF is not currently accepting telescope proposals. Please be aware that any proposals you construct are not guaranteed to be valid for the next proposal round.


Using OPAL is a four step process: prepare; preview; submit; and review

To submit a proposal, you must have a registered OPAL account.

OPAL proposals generally require three components:

  1. A cover sheet created with the cover sheet editor.
  2. An observations table created with the observations table editor.
  3. A scientific justification in PDF format (<10 megabytes and not more than three pages in total — see the science case requirements) created by any tool you wish to use. This is not required for projects that have pre-graded project status.

See the full information on ATNF Telescope Applications.

In particular please read the web information on the current status of the ATNF telescopes.

OPAL supports Firefox and Internet Explorer. More about OPAL.
