Applications may be submitted once per semester, the next deadline for filler proposals is Octo3:00 am (UT). In recent semesters, typically of order 15% of HSC time has gone to filler programs.

Execution is not guaranteed: observations are made only when there is no other program in the HSC queue. Targets are generally limited to 4 1.5 arcseconds, and/or poor transparency), up to 35 hours can be requested by a filler proposal. POLISH-2, a high-precision polarimeter will be available for science (subject to demand) as visiting instrument at Gemini North in 2021A.MAROON-X, a high-resolution (R~80,000), optical (500 - 900nm) spectrometer, will be available for science (subject to demand) as a visiting instrument at Gemini North in 2021A.IGRINS, a high-resolution (R~45000), single-setting, near IR (1.45 - 2.5 microns) echelle spectrometer, will be available for science (subject to demand) as visiting instrument at Gemini South in 2021A.'Alopeke and Zorro, the fast low-noise dual-channel and dual-plate-scale imagers with speckle and wide-field modes, will be available for science (subject to demand) as resident visiting instruments at Gemini North and Gemini South, respectively, in 2021A.Because of the global pandemic, we are not accepting visitors until further notice, and the "Bring One, Get One" Student Observer Support Program" program remains unavailable.Please check carefully the information provided in the Phase I Submission Guidelines section below. Remember that Gemini PIT automatically adds the time for baseline calibrations to the total time requested for each target in the proposal.We kindly ask you to fill the gender field in the investigator details section of the Phase I Tool (PIT). Gemini is producing gender statistics to measure and monitor gender equality across the submitted and successful proposals.See Other Proposal Opportunities for details. The Gemini community is eligible to propose Hyper Suprime-Cam (HSC) "filler" programs on Subaru in 2021A.Proposers from the Subaru Community, who are applying for Gemini Time, should also submit their proposals via the Subaru webform by Septem12:00 (Noon), Japan Standard Time.CFHT has requested 7 nights of exchange time for the 2021A semester, so 9 hours available on both Gemini North and Gemini South for the French community, and 15 hours available on both Gemini North and Gemini South for Canada and 10 hours on Gemini North for UH included in the time avaialble for queue).More details on the magnitude limits can be found on the GSAOI web page. For users of GeMS/GSAOI, much fainter guide stars can now be selected due to the new natural guide star unit, thus increasing the sky coverage.GNIRS (1-5 micron spectrometer) is expected to be off the telescope for about a month in April/May for IFU installation.ALTAIR is not available for the 2021A semester. Altair (facility Adaptive Optics system) is currently not working and is under repair.However significant changes can happen and impact the available observing time and instruments, due to the continuing impact of the COVID-19 pandemic. Gemini is planning the 2021A semester call for proposal as usual.Please see the relevant instrument pages and subsections of the call for proposals for details. The following capabilities and announcements are notable for the 2021A semester. The distribution of time across the partners is available in the time distribution table. 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. The Call is open to all participants and host institutions : Argentina, Brazil, Canada, Korea, the United States, Chileand the University of Hawaii.
