tion (R = 45,000), has been on Gemini South for 50 nights in 2018A. A stalwart team of postdocs, students, and faculty from Korea and the United States are supporting the instrument, and the observations are going very well. We are discussing possibilities for a longer visit in the future. You can find more information on IGRINS’ commissioning and first light on page 19 of this issue of Gemi- niFocus. ‘Alopeke (a contemporary Hawaiian word for “fox”) is an agile dual-purpose speckle imager that provides diffraction-limited performance on an 8-meter telescope. This upgraded version of its older sibling, the Dif- ferential Speckle Survey Instrument (DSSI) now has its own special location on Gemini North: mounted between the Gemini Cali- bration Unit and the Instrument Support Structure, so that we don’t need to remove it between observing runs. ‘Alopeke will con- tinue to be offered regularly to provide out- standing imaging capabilities. DSSI is still performing well, having spent a few nights on Gemini South this year for a terrific observing run, capturing upwards of 100 targets per night. Next year, keep an eye out for another upgraded and permanently mounted version of DSSI, called Zorro, to ap- pear at Gemini South. High-precision polarimeters now abound at Gemini with the promise of two new and exciting visiting instruments: POLISH-2 (aimed at exoplanet reflection polarimetry) and HIPPI-2 (designed to capture the di- rect polarization signatures of exoplanets). POLISH-2 will have its first observing run in 2018B; we look forward to hosting this instrument for a few nights in August on Gemini North and seeing the great science it can do. HIPPI-2, visiting from the Univer- sity of New South Wales, is scheduled for commissioning soon; it may be ready to join the party in the next few semesters. 18 GeminiFocus Planning Ahead We are also very excited to be preparing for MAROON-X — a new visiting exo-Earth finder from the University of Chicago. This fiber-fed, red-optical, high-precision, radial- velocity spectrograph is expected to not only identify and characterize nearby habit- able exoplanets, but ultimately make a cred- ible search for life on planets outside the Solar System. Currently, it is scheduled to be deployed at Gemini North next year, and we are in the process of installing an enclosure in the Pier Lab that will help regulate the temperature and vibration environment for this advanced instrument. The instrument itself is expected to be commissioned on Maunakea in early 2019. Look for more re- ports on the results of testing next year, with a full description of the exciting capabilities that MAROON-X will bring to Gemini. Looking even further ahead, we are work- ing with a great team of folks from several institutions in Canada to bring the Gemini Infrared Multi-Object Spectrograph (GIR- MOS) to Gemini around 2024. GIRMOS is an ambitious project designed to provide Gemini with high performance multi-object adaptive optics, and the ability to carry out simultaneous high-angular-resolution spa- tially resolved infrared spectroscopy of four objects within a two arcminute field when used with the Gemini Multi-conjugate adap- tive optics System. These are only a few of the visiting instru- ments planned for deployment on the Gemini telescopes in the next several years. You can find more information on these and others at this link. Watch for announcements later this year to see what will be available for the 2019A Call for Proposals! July 2018
