Apply now for:

• Our ASKAP radio telescope (including CRACO)
• Our Australia Telescope Compact Array
• Murriyang, our 64-m Parkes radio telescope
• The Tidbinbilla radio antennas: the 70-m antenna Ballima (DSS-43) , and the 34-m (DSS-34) antenna;

Mark your calendars: the deadline for all proposals is 06:00 UT (17:00 Sydney local time) on Tuesday, 17 June 2025.

To submit your proposal, visit our online proposal application system, OPAL.

Important updates for 2025OCT:

• Since February 2025, the Cryogenically Cooled Phased Array Feed (CryoPAF) has been installed in the focus cabin of Murriyang, our 64-m Parkes radio telescope.
• BIGCAT commissioning is underway during 2025APR meaning that BIGCAT will be offered in shared-risk mode during the 2025OCT semester. Since the ATCA schedule for 2025APR has not yet been released, teams that wish to carry over their proposals in 2025OCT can request pre-graded status.
• ATNF proposals are fully anonymised. Proposals that reveal applicant identities will be penalised by a reduction of scores or outright rejection for blatant breaches of anonymity (e.g. self-citations where the first author is listed by name).
• We strongly encourage proposers to use this LaTeX template for ATNF scientific justifications  (with appropriate BibTeX setup to support anonymisation). 
• ATNF long-term proposals are only accepted once per year at the December deadline. As such, long-term proposals will NOT be accepted this semester.

We encourage OPAL users to report any issues via email (atnf-datasup@csiro.au). The file format for cover sheets and observations tables was changed in 2022OCT. If you have files (in OXML format) from 2022APR and previous semesters please reload them into the OPAL editors, carefully re-check and update them, and save them in the new JSON format.
