As part of Gemini’s comprehensive energy savings initiative, Gemini North Telescope Facility (GN) seeks to install a 94.8 kW, net-energy metered photo-voltaic power system on the GN support building located at the Hilo Base Facility in Hilo, Hawaii. The proposed PV system consists 378 modules having a DC capacity of 260 W per module (98.28 kW DC total) and 4 decentralized inverters having a rated AC capacity of 24 kW AC per inverter (94.8 kW AC total). The system shall be configured in a 480 volt 3-phase arrangement.
In preparation for the start of 2015B, all new Fast Turnaround (FT), Director's Discretionary (DD) time, and Poor Weather (PW) proposals must use the 2015B Phase I Tool (PIT). See the PIT Version Table for more information and download links.
The Gemini South observing database is back online after the shutdown due to the July 12 snowstorm.
The Phase 2 deadline for 2015B Gemini South programs is now the end of the workday on Tuesday, July 21.
Please submit a Helpdesk ticket if you have any problems or questions.

To properly reduce GPI observations one must download the proper calibrations. This document describes how the user can download all types of calibrations from the GSA. The user should read the instructions here on how to access the GSA, these instructions are only details on how to access GPI particular data.

This section contains instructions for configuring GPI at phase II. It is organised as follows:
A Gemini Facility Calibration Unit (GCAL) is available on each Gemini telescope, providing continuum and line emission light sources for wavelength and flat-field calibrations. Each GCAL is located permanently on one port of the instrument support structure and light is directed into an instrument by the science fold mirror. The GCAL optics simulate the f/16 telescope beam, illuminating the instrument pupil in the same way as light from an astronomical source.
