  • February 2024: Call to join the Early Science Team (EST)
  • April 2024: Early Science Team composition announced


The IGRINS-2 System Verification observing run is planned for July 2024. The purpose of the run is to:

  • perform end-to-end testing of the software, documentation, and operational procedures to prepare for instrument deployment (i.e. November IGRINS-2 Shared Risk Call for Fast Turnaround, Regular operations in 2025A and beyond); and
  • provide an initial set of publicly available observations to showcase the instrument capabilities, the range of science cases, and inform the community in preparation for the call for proposals.

The International Gemini Observatory has allocated about 40 hours of engineering time for IGRINS-2 observations.

The Early Science Team (EST), which includes Gemini Observatory personnel and community representatives, will be responsible for developing the observations to take for the SV, reducing and analyzing the data, evaluating the observations, and presenting the results to support and promote the use of IGRINS-2 among the broader Gemini community. The EST is chosen in consultation with the Gemini Directorate, STAC, and the IGRINS-2 Instrument team.

Regular updates on the IGRINS-2 System Verification observation planning and results will be presented on this page. An expected timeline is provided below.

15 March 2024: Deadline for EST self-nomination.

5 April 2024: EST composition is announced.

May-June: SV Observing plan (with priority) is finalized (the EST tests the Integration Time Calculator and the Phase I Tool software; the SV team tests the Observing Tool). The Target list is released to the community.

July: Observations will be performed around 17-23 July. Description of the observations is released.

August: Raw data released. Data quality evaluation released.

September-October: Reduced data released. 

November: IGRINS-2 will be offered in Shared Risk for Fast Turnaround proposals.
