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 and view your proposals, you must have a registered OPAL account.

OPAL proposals generally require three components:

  1. A cover sheet created with the cover sheet editor (login required).
  2. An observations table created with the observations table editor (login required).
  3. A scientific justification in PDF format (<10 megabytes and not more than three pages in total — see the science case requirements). This is not required for projects that have pre-graded project status. We strongly encourage proposers to use the Overleaf LaTeX template available here to create the scientific justification PDF.

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 most current web browsers. More about OPAL.
