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 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.
