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 Gemini Observatory Archive. The user should read the instructions here on how to access the GOA, these instructions are only details on how to access GPI particular data. 

Gemini North Shutdown Aug 10-31 to repair bottom shutter

The Gemini North enclosure bottom shutter experienced a drive shaft bearing failure in one of the two driveboxes during the night of July 27, similar to what happened to the Gemini North enclosure top shutter in 2014. The next day, the day crew locked out the bottom shutter at a position that has limited the telescope lower elevation to 38 degrees above horizon, while we continue to observe at night.

Gemini Tracks Collapse of Io's Atmosphere During Frigid Eclipses

Artist’s concept of the atmospheric collapse of Jupiter’s volcanic moon Io, which is eclipsed by Jupiter for two hours of each day (1.7 Earth days). The resulting temperature drop freezes sulfur dioxide gas, causing the atmosphere to “deflate,” as seen in the shadowed area on the left. Credits: SwRI/Andrew Blanchard.

Gemini Observatory Instrumental in Exoplanet Harvest

Gemini Strategic Vision Survey now open

The Gemini Observatory starts focusing on the future, specifically on what Gemini will look like beyond the year 2020. The Gemini Board of Directors has set up a Strategic Vision Committee, whose charge can be found on Gemini’s website. In essence, the Strategic Vision identifies the Observatory’s purpose, direction, and fundamental principles. It directly addresses the role the Observatory will play beyond 2021 and considers a variety of funding and partnership scenarios. By the end of this year, the Strategic Vision will be in place.

Instructions for Designing a MOS Mask

This page gives step-by-step instructions for designing masks for MOS observations with GMOS. The required steps are:

Exploring a Frozen Extrasolar World

July call for proposals

Gemini North and South are accepting proposals for the Fast Turnaround (FT) program. Here, we give information specific to this proposal cycle. Please see the other FT pages - particularly the rules - for general information about the program. FT-specific proposal templates must now be used for all FT proposals; see the "PIT information" section below.

Order-blocking, Acquisition, and Neutral Density Filters

The filters listed below are used during spectroscopy for order-blocking and (with the exceptions of M, L, and XD) for acquisition. For acquisition they provide complete and unvignetted views of the acquisition "keyhole," whose dimensions are shown here.

Special proposals require 2016B PIT

In preparation for the start of 2016B, all Director's Discretionary (DD) time and Poor Weather (PW) proposals must use the 2016B Phase I Tool (PIT). See the PIT Version Table for more information and download links.
