Semester 2019A Call for Proposal
Gemini Observatory invites its community to propose scientific investigations for the 2019A semester, 1 February 2019 - 31 July 2019
The submission deadline varies with participant. Multi-participant joint proposals should be submitted by the deadline of the participant country to which the Principal Investigator is affiliated. The table below shows submission deadlines for (i) all Gemini Participants, (ii) the Subaru community under the Gemini/Subaru time exchange, and (iii) the French community under the GRACES collaboration. An overview of the Gemini proposal submission and time allocation process is given here.
Participant | Submission Deadline |
United States | October 01, 2018 at 23:59 (Mountain Standard Time) |
Canada | October 01, 2018 at 16:00 (Pacific Daylight Time) |
Brazil | October 02, 2018 at 23:59 (Brasília Time) |
Argentina | September 30, 2018 at 23:59 (Argentina Time) |
Korea | October 02, 2018 at 23:59 (Korea Standard Time) |
Chile | October 01, 2018 at 23:59 (Chile Time) |
U. of Hawaii | October 01, 2018 at 10:00 (Hawaii-Aleutian Standard Time) |
Subaru Community | September 30, 2018 at 23:59 (Hawaii-Aleutian Standard Time) |
French Community | October 02, 2018 at 23:59 (Universal Time) |
The Call is open to all participants and host institutions : Argentina, Brazil, Canada, Korea, the United States, Chile and the University of Hawaii. US time is open to all astronomers worldwide including those at non-US institutions, although in that case the proposal must explain why U.S. national facilities are needed. The distribution of time across the partners is available in the time distribution table.

New and Notable in 2019A!
The following capabilities and announcements are notable for the 2019A semester. Please see the relevant instrument pages and subsections of the call for proposals for details. General:

Summary of 2019A Gemini Capabilities
Gemini North
Targets are generally limited to 4 < RA hours < 1 and -37 < DEC degrees < +90. In some cases there are additional constraints as described below and in the target accessibility and instrument restrictions page. The Gemini North Laser Guide Star (LGS) system is not offered for regular programs in 2019A. It will be offered via the Fast Turnaround (FT) Program and the Director's Discretionary Time program as soon as it is successfully commissioned. |
Facility instruments offered in 2019A, in queue or classical mode, are:
|
Visitor instruments offered in 2019A (subject to demand) are:
|
Gemini South
Targets are generally limited to 5 < RA hours < 2 and -90° < dec < +28°. In some cases there are additional constraints as described in the target accessibility and instrument restrictions page. |
Facility instruments offered in 2019A, in queue or classical mode, are:
|
Visitor instruments offered in 2019A(subject to demand) are:
|
Important Dates for 2019A
The deadline for Phase I submission varies with participant (see the submission deadline Table at the top of this CfP). For successful proposals, both queue and classical, the Phase II submission deadline is 18 of January 2019. Check the 2019A schedule for key dates and events in the proposal process .
Phase I Submission Guidelines for 2019A
Proposals for time on Gemini, and for time on Subaru via the Gemini-Subaru time exchange program, must use the Gemini Phase I Tool (PIT). Latex and Word templates are available to create a pdf attachment which includes the science and technical cases. See the PIT page for installation information and the PIT help pages for assistance. Investigators proposing for facility instruments are requested to include the output from the integration time calculators in the proposal. Investigators proposing for POLISH-2 visitor instrument must use the generic Visitor instrument option in the PIT resource list.
Note that, following the Board resolution 2016.A.2, the time for baseline partner calibrations for the Gemini facility instruments and the named visitor instruments (DSSI, TEXES, Phoenix, 'Alopeke) are now automatically added to the total time requested for each target in the PIT. Investigators should continue to include the time associated to overheads (acquisition time, readout time, etc) in the total time estimated for each target in the PIT. See the Observing Section in the PIT help pages for details.
Time Available in 2019A
The time available for each participant and host institution in 2019A is shown on the time distribution page. At Gemini North, 171 nights are expected to be available for science. At Gemini South, 168 nights are expected to be available for science.
Subaru Exchange Time
The exchange of time between the Gemini and Subaru communities will continue in 2019A. Gemini and Subaru expect to be able to exchange a minimum of 5 nights in semester 2019A. Note that additional nights may be allocated on Subaru in 2019A in benefit of the Gemini community. PIs from the Gemini community are strongly encourage to propose for observations on Subaru.

Priority Visitor Observing Mode
In Priority Visitor Observing, a visiting observer comes to the Observatory for a block exceeding their program's time allocation, and elects when to carry out their program within that block. This may be when conditions are within their requirement, better than their requirement or even fail to meet their requirement. If time remains on the program after the observing time is complete, the program carries on in the regular queue with priority given by the TAC-assigned science ranking band. When not executing their own program the visiting observer will execute other Gemini queue observations. PV observing mode is offered as a possibility for band 1 queue programs in 2019A. Investigators wishing to have their program considered for PV observing should indicate their desire to participate in the Technical Design portion of their 2019A queue proposal.
Other Proposal Opportunities in 2019A
Other proposal opportunities are available at Gemini Observatory in 2019A. These include:
- The Fast Turnaround (FT) Program provides monthly opportunities to submit proposals, with successful programs scheduled for observation starting one month after each proposal deadline. Up to 10% of the time at Gemini North and Gemini South is available for the FT programs.
- Director's Discretionary Time is open to any astronomer worldwide and proposals can be submitted at any time.
- Poor Weather Proposals are solicited for programs that can use poor, but usable, conditions and are executed when nothing in the regular queue is observable. Proposals can be submitted via the normal TAC process (this call) or at any time.
- For Semester 2019A, the Gemini community is also eligible to propose HyperSuprimeCam (HSC) filler programs on Subaru. Filler programs are executed in poor observing conditions (typically seeing >1.5 arcseconds, and/or poor transparency), up to 35 hours can be requested by a filler proposal. Execution is not guaranteed: observations are made only when there is no other program in the HSC queue. In recent semesters, typically of order 15% of HSC time has gone to filler programs. Applications may be submitted once per semester, the next deadline for filler proposals is October 11th 3:00 am (UT). Proposals must be sent through the Subaru submission system (NOT Gemini), and are considered only by the Subaru TAC. Note that only a short text summary of the program is required, not a full detailed Science Justification.
Remote Eavesdropping
Remote Eavesdropping will be available in 2019A for all queue programs. Investigators will be invited to sign up for eavesdropping via the PI email announcing they have been granted time.
Data Rights, Proprietary periods and Data Distribution
The data taken with the Gemini telescopes is the property of the Gemini Observatory. Principal investigators of Gemini regular programs (Queue/Classical/Poor Weather) have exclusive access to the data for their program for a period of 12 months. After the proprietary period the data are publicly available. See the page Data Rights and Proprietary Periods for more information.
All data, including raw and available processed data, obtained with the Gemini telescope are distributed exclusively through the Gemini Observatory Archive. More information about the data distribution is given here.
