Dear colleague,



Proposals for observing time are now invited for the 2024OCT semester for the:

* ASKAP radio telescope;

* Australia Telescope Compact Array (ATCA);

* Murriyang, the 64-m Parkes radio telescope;

* Tidbinbilla 70-m and 34-m antennas; and

* Long Baseline Array (VLBI).



The deadline for all
proposals is 07:00 UT (17:00 Sydney local time) on Friday, 14 June 2024.



All proposals must be submitted using the online proposal application system,
OPAL (http://opal.atnf.csiro.au/).



Significant changes for the 2024OCT semester are detailed here and include:

* We expect to install the Cryogenically Cooled Phased Array Feed (CryoPAF) on
Murriyang, the 64-m Parkes radio telescope, during Q3 2024. We are seeking
expressions of interest for shared-risk CryoPAF time during January through
March 2025.

* We expect to replace CABB with the BIGCAT upgrade to ATCA during the 2024OCT
semester, but the installation date is yet to be confirmed. If your proposed
project can only be carried out with either CABB or BIGCAT this should be
clearly stated within the proposal text.

* ATNF proposals are fully anonymised. Proposals that reveal applicant
identities will be penalised.

* We strongly encourage proposers to use the provided LaTeX template for ATNF
scientific justifications, with appropriate BibTeX setup to support
anonymisation.



Details of these changes and other important information on the current status
of ATNF telescopes is provided at https://www.atnf.csiro.au/observers/apply/avail.html
