  • Read more about 2012A Call for proposals announced

Gemini is now accepting proposals for observing time in Semester 2012A. The proposal deadline is September 30, 2011. A new version of the Phase I Tool (PIT) has been released to support proposal submissions.

2012A PIT released

Submitted by sleggett on August 31, 2011
  • Read more about 2012A PIT released

The Phase I Tool (PIT) for semester 2012A observing proposals has been released. Poor weather and Director's time proposals during the remainder of semester 2011B should continue to use the 2011B PIT.

Updated beta version of the Gemini IRAF package released

Submitted by sleggett on August 18, 2011
  • Read more about Updated beta version of the Gemini IRAF package released
An updated beta version of the Gemini IRAF package (v1.11beta2) has been released. This version is required for processing new GNIRS data from Gemini North and includes a complete set of MDFs, configuration files and examples. This beta version of the Gemini IRAF package should not be used to process data other than GNIRS data, since rigorous testing of the reduction of other types of data has not been completed at this time. Please see Gemini Data Processing Software page for more information.

GPI science campaign

Submitted by nlevenson on May 17, 2011
  • Read more about GPI science campaign

There was great interest in the Gemini Planet Imager campaign science program, with a total of over 6500 hours of time requested.  The approved program, led by Bruce Macintosh (Lawrence Livermore National Laboratory), will conduct a comprehensive survey to yield a robust census of extrasolar giant planets.  GPI will also be available for general community use.

International Gemini Observatory

The International Gemini Observatory  provides the astronomical communities in six participant countries with state-of-the-art astronomical facilities that allocate observing time in proportion to each country's contribution. In addition to financial support, each country also contributes significant scientific and technical resources. The national research agencies that form the Gemini partnership include: the US National Science Foundation (NSF), the Canadian National Research Council (NRC), the Chilean Agencia Nacional de Investigación y Desarrollo (ANID), the Brazilian Ministério da Ciência, Tecnologia e Inovação, the Argentinean Ministerio de Ciencia, Tecnología e Innovación, and the Korea Astronomy and Space Institute (KASI). The observatory is managed by the Association of Universities for Research in Astronomy, Inc. (AURA) under a cooperative agreement with the NSF. The NSF also serves as the executive agency for the international partnership.
