Call for Proposals

To: Observers on the Automated Planet Finder (APF) 2.4 m telescope
From: Claire Max, UCO Director
Date: September 11th, 2020
Semester 2021A
(February 1st 2021 through July 31st, 2021)

Deadline: Monday, Oct 12st, 2020 at 5:00 pm PDT/strong>

  • Requested nights should be “clear” nights with no correction for weather.
  • The TAC will be allocating time based on the expected 800 hours of clear time for UC proposals.
  • Queue priorities will be set based on TAC grades.
  • We plan on taking two full weeks in February to recoat the secondary and tertiary. Given the usual weather history of MH, this is the month we are most likely not to be able to observe so we will not adjust the expected amount of open time.

Proposal Information

Information about the APF telescope can be found at:

For the 2021A semester, 800 hours of the time the 1000 clear hours available on the APF will be open for UC proposals for February 2021 through the end of July 2021.

The time will be scheduled in two different modes at the request of the observers. The observer can (1) ask for their targets to be inserted into the queue operated by the University of California Observatories (Cadence), or (2) ask for specific nights and conduct observations as they wish (Classical). Classical requests need to be justified.

All time requests should be in hours. The cover sheet should list the request in nights, assuming 10 hours per night, with fractional nights as appropriate. The TAC will allocate grades to the proposals and those grades (A, B, C) will determine the relative priority on any given night, with guaranteed or purchased time being granted A time.

The queue will be run on all nights, except for the whole or half nights allocated to specific classical programs. The queue software is capable of handling multiple programs per night. The target list and the data files for a given observer will be private to the PI unless otherwise requested. A given program can be executed on any given night the queue is running, with the balance of observing time monitored over the course of the semester to match the allocated amount. Simple cadence requirements, ranging from multiple times a night, to once a month can be met and the total observations can easily be supported.
