Applying for Magellan

Call for Proposals for Scientific Use of the Magellan Telescopes in Semester 2018A

Proposal Deadline

Australian proposals for Magellan time in Semester 2018A (mid-Jan to mid-July 2018) must be submitted electronically by:


5:00pm Australian Eastern Standard Time, Friday 6th October 2017


Note that Daylight Saving time is in effect in all states except WA, QLD, and the Northern Territory from 1 Oct 2017. However the proposal deadline is always Australian Eastern Standard Time.

What's New in Semester 2018A?

The instruments normally available on the two Magellan telescopes are listed on the ITSO Magellan instrumentation page, but applicants should bear in mind the following for Semester 2018A:

  • A new CCD is currently being commissioned with the Planet Finding Spectrograph. Contact Jeff Crane (crane -@- for the latest update before applying.
  • There will likely be a single MegaCam f/5 block; a single MagAO block in the April bright time; and perhaps 2 M2FS blocks in 2018A, depending on demand. Any partner that wishes to allocate time with MegaCam will need to contribute additional time for Engineering to install and remove MegaCam.
  • The Parallel Imager for Southern Cosmology Observations (PISCO) provides simultaneous imaging in the 4 SDSS bands g', r', i', and z' over a 7.3 x 5.4 arcminute field of view at 0.11 arcsec/pixel. PISCO is a PI instrument and is only available via collaborative arrangement with the instrument team. Contact Tony Stark (astark -@- before submitting a proposal.

Available Time

ATAC will notionally have eight nights total on Magellan to allocate in Semester 2018A. The exact nights, and the split between telescopes and dark/grey/bright time will be decided after ATAC has met, in negotiation with the Magellan Scheduler.

Note that demand for the instruments on Clay has recently greatly exceeded that for the Baade, so you may wish to consider whether your program might still be possible using a different instrument (e.g. IMACS instead of MagE or MegaCam). ATAC welcomes more ambitious Magellan proposals seeking substantial fractions of Australian time, as well as large programs seeking time jointly with other Magellan partners.

Observing at Magellan

Note that this is "classical" observing time - someone will need to go to the telescope to carry out the observations. At least one of the people going to the telescope should be an experienced observer, as only limited technical support is provided by Las Campanas Observatory. You will need to arrive early to familiarise yourself with the telescopes and instruments. ITSO will reimburse eligible observers from Australian institutions for the cost of travel to observe in Chile.

While remote observing is not yet offered at Magellan, "remote eavesdropping" is an option for collaborators who may not be able to travel to Chile, but would still like to be an active participant in the observing. At least one experienced observer will still need to travel to the telescope, but others can join in via Skype and view instrument or data reduction displays with the "Share screens" option. Currently bandwidth limitations preclude transferring raw data files, or X-displays via ssh or VNC from Chile to Australia. If you would be interested in the remote eavesdropping option then please contact Francesco Di Mille (fdimille -@-
