PATT Call for Proposals for the Liverpool Telescope – Change to Proposal Deadline

April 6, 2020, from Astrolists

The deadline for submission of proposals has been delayed to 23:59 GMT on Thursday 30th April 2020.

The Liverpool Telescope is a 2.0 metre fully robotic facility sited at Observatorio del Roque de Los Muchachos, La Palma, Canary Islands. The Liverpool Telescope Time Allocation Committee is now accepting proposals for PATT time for observations in Semester 2020B (1st Jul 2020 – 28th Feb 2021). Full details of the telescope, instrumentation and proposal submission process (Phase 1) are available from:

Application via PATT is open to members of UK institutes, as well as non-UK applicants who are not eligible to apply for Liverpool Telescope time via other routes.

We would also like to update users on the observatory status during the current global health crisis. At the time of writing the telescope continues to operate more-or-less as normal. Due to the difficulty of getting on-site support at weekends we will not be operating on Friday and Saturday nights, but otherwise operations are unaffected.

The routes to obtaining telescope time outside of the semesterly application process remain open, and we can typically approve such applications the same day we receive the proposal.

PATT allocates 20 hours “A” time per semester to Reactive Time. This is time intended primarily for unforeseen targets-of-opportunity and can be applied for via a simple web form. More details can be found here:

We also offer ‘PriorityZ’ time, which is for long-term, queue filling programmes which are backup to the main science programme of the telescope. We would typically expect to approve a PriorityZ proposal for a period of two years. Again, this time can be applied for via a web form, and details can be found here:
