Status and Availability
GSAOI and GeMS will be offered to the community in the 2013B call for proposals. It is expected that the instruments will be available for regular observations between September 2013 and January 2014 in queue mode only.
18 - 22 February 2013
First GeMS/GSAOI run in queue. During the run, we completed three more SV programs and started to observe some of the 2013A queue programs.
25 January 2013 - 2 February 2013
14th GeMS/GSAOI commissioning run. During this run, we have completed six SV programs and made good progress on another three. In optimal seeing, the first diffraction ring has been visible on point sources, and even in poor seeing, the AO correction is excellent. The GSAOI commissioning is almost completed.
26 December 2012 - 1 January 2013
13th GeMS/GSAOI commissioning run. The run was focused on the optimization of GeMS, complete pending GSAOI commissioning tasks and start the observations of the approved SV programs. Very successfully run. See http://www.gemini.edu/node/11925 for details about the Orion bullet image obtained with GeMS/GSAOI. In addition, some of the SV programs were started.
15 December 2012
Engineers have been working hard to fix the problem with the filter wheel 1 on GSAOI. After several days of work and motor replacement, the GSAOI filter wheel 1 come back. The filter wheel 1 was extensively tested with no failures. The instrument is ready for the next GeMS/GSAOI commissioning run.
3 - 9 November 2012
12th GeMS/GSAOI commissioning run. Problems with the filter wheel 1 prevented us to use some of the broad band filters in GSAOI. Unfortunately the poor weather, the problem with the filter wheel 1 and the low laser power prevented us to complete of the commissioning tasks.
14 October 2012
GeMS/GSAOI System Verification proposals produced some 29 applications, from which 13 were selected. We received about three times as many proposals as we required. The final selection can be see at http://www.gemini.edu/sciops/instruments/gsaoi/systemverification?q=node/11895.
1 September 2012
GeMS/GSAOI is offering to the community for semester 2013A. The instruments are offering in a shared-risk mode for a total of around 100 hours.
27 August 2012
GeMS/GSAOI System Verification (SV) call for proposal has been released. Approximately 60 hours of SV time is available in the 2012B semester. We expect to observe SV programs between December 1, 2012 and January 31, 2013. See
02 May 2012
GSAOI is removed from the telescope to the Instrument Laboratory for a general engineering maintenance. GSAOI commissioning will be resumed at the end of October 2012.
26 - 30 April 2012
11th GeMS/GSAOI commissioning run. The poor weather was a major issue during the commissioning run. Most of the nights were lost due to poor weather, however useful data were obtained to complete some of the high priority GSAOI commissioning tasks.
9 - 15 April 2012
10th GeMS/GSAOI commissioning run. Most of the nights were lost due to poor weather that prevented to complete the planned GSAOI commissioning tasks for this period.
20 March 2012
Call for community commissioning targets released. See http://www.gemini.edu/node/11800 for details.
8 - 15 March 2012
9th GeMS/GSAOI commissioning run. Unfortunately, a cooling problem with GSAOI prevented the use of the instrument during the commissioning run. The cooling problem in GSAOI didn't stop the GeMS commissioning to continue. The GeMS team used GMOS for commissioning/verification purposes and to demonstrate the capability of GeMS below 1 µm.
4 March 2012
GSAOI is installed back at the telescope after the replacement of the entrance window. The instrument is cold and ready for the next commissioning run.
21 February 2012
GSAOI is removed from the telescope to the Instrument Laboratory. The instrument will be warmed up in order to replace the damaged entrance window, which lost the coating in the central region of the window. The work will take 10 days.
6 - 14 February 2012
8th GeMS/GSAOI commissioning run. During this commissioning run we concentrated in the characterize of the new Natural Guide Star Wave Front Sensor Probe 1 installed in Canopus. The team completed the Canopus and ODGW mapping. The variable seeing was an issue during the run. Images of a blank sky region were obtained to calculate the background contribution in all filters. Continue to monitor the system throughput using different filters. We have discovered a problem with the coating in the GSAOI entrance window. This problem can affect the system throughput. Analysis in on-going to evaluate how muh sensitivity we are loosing. Obtained a good set of engineering images on nice targets.
6 - 12 Jan 2012
7th GeMS/GSAOI commissioning run. The GSAOI science team completed the detector characterization (read noise and gain determination, non-linearity correction, detectors linearity), derived a final values for the Instrument Alignment Angle and WCS solutions, obtained data for throughput measurements for different filters and exercised the acquisition procedures for different type of targets. A very successful run.
12 - 20 Dec 2011
A very successful 7th GeMS commissioning run with GSAOI installed on port 1 of the ISS. The run was focused on the optimization of GeMS and to demonstrate the potential of the system. See http://www.gemini.edu/node/11715 for details about the first light ultra-sharp wide field image obtained with GeMS and GSAOI. At the same time, the GSAOI science team continued to make a good progress in several instrument related commissioning tasks.
27 Nov 2011
GSAOI is installed back at the telescope after a five-month of maintenance. During this period, the detector controller and component controller software were updated, and the GSAOI Environmental Window was cleaned from dust accidentally accumulated after the instrument was installed on port 5 of the ISS in January 2011.
12 - 20 Nov 2011
6th GeMS commissioning run. GSAOI is planned to be installed back on the ISS at the end of November.
3 June 2011
GSAOI is removed from the telescope to the Instrument Laboratory for a general engineering maintenance. GSAOI commissioning will be resumed at the end of 2011.
17 - 22 May 2011
5th GeMS/GSAOI commissioning run. Most of the nights were lost due to poor weather that prevented to complete the planned GSAOI commissioning tasks for this period.
16 - 22 April 2011
4th GeMS/GSAOI commissioning run with the Laser fully operational. The GSAOI science team continues to make a good progress in several commissioning tasks, like on-sky orientation, WCS, etc. On April 19, 2011, the engineering first light image is obtained with GeMS and GSAOI (see the press release).
21 - 27 March 2011
3rd GeMS/GSAOI commissioning run with the Laser fully operational. The visiting ANU team and the GSAOI science team made a good progress in several GSAOI pre-commissioning tasks. The GeMS team were able to close the loop with the laser and the NGS tip tilt.
20 - 27 February 2011
2nd GeMS commissioning run with GSAOI installed on port 5 of the ISS. At this stage, GSAOI is used only to characterize the Laser and the AO bench (Canopus).
13 January 2011
GSAOI was installed on port 5 of the ISS on Gemini South. The visiting ANU team and the GSAOI science team are currently completing checks to ensure the installation was successful.
GSAOI installation on Gemini South Observatory (January 13, 2011)
9 January 2011
An Australia National University (ANU) team consisting of Peter Young and Matthew Doolan arrive at Gemini South in preparation for the installation of GSAOI on the telescope
16 August 2010
An Australia National University (ANU) team consisting of Peter McGregor (PI), Peter Young, Matthew Doolan, and Jan van Harmelen visited Gemini South for a week to provide advance training to the Gemini South GSAOI science and engineering teams. The visit was successful. Plans for installation and commissioning are progressing for early 2011.
