<p style="margin-bottom:8.0pt;background:white"><span style="font-family:"Aptos",sans-serif;color:black">The Australian Time Allocation Committee (ATAC) is issuing a delta call soliciting proposals to use
<b>instruments at the Cassegrain focus (Veloce, KOALA or visitor’s instruments e.g. HIPPI)</b> on the Anglo-Australian Telescope between 1 March and 31 July 2024.</span><o:p></o:p></p>
<p style="margin-bottom:8.0pt;background:white"><span style="font-family:"Aptos",sans-serif;color:black;background:yellow">This delta call arises from ongoing difficulties repairing 2dF, resulting in the instrument being taken off the telescope for a minimum
of three months (to 30 April 2024) and therefore requiring the AAT to be rescheduled. While the period 1 March to 30 April will be rescheduled, we are soliciting proposals to the end of the 2024A semester (31 July 2024) in case further time is needed to repair
2dF. Any proposals for observing between 1 May and 31 July should be aware that they will only be scheduled if 2dF is not fixed by 30 April.</span><o:p></o:p></p>
<p style="margin-bottom:8.0pt;background:white"><span style="font-family:"Aptos",sans-serif;color:black">The deadline for proposals is
