Cancelation of the November GeMS run

November 24th, 2015

The GeMS / GSAOI laser run that was planned to take place this week had to be canceled. Unfortunately the laser and the Canopus Real Time Control system were not operational and in spite of intense efforts to resolve these problems in time for the laser window there was just not sufficient time to get the system in an operational state. We will continue to work towards ensuring that the upcoming January GeMS / GSAOI run will be a success.

Gemini-S shutdown work completed

November 2nd, 2015

The Gemini-S telescope is now back into operation following the planned maintenance shutdown.

Main events during this year’s shutdown was the re-coating of the primary mirror, and the investigation into the problems with the GMOS-S CCDs, in particular the intermittent charge spreading that has plagued CCD1. Both these main events, and many other activities were executed successfully and within the planned time.

Gemini-South telescope back in business after earthquake

September 28th, 2015

The Gemini-S telescope survived an 8.4 magnitude earthquake the previous week. Following an intense week of detailed inspections and testing of the infrastructure, the telescope, and the instruments were released for normal use. During the inspection some components were found broken or displaced, but all could be repaired and adjusted and no major damage was sustained. 

On-sky tests over the weekend showed that all is well and science observations have resumed. 

We are all much looking forward to delivering top-quality science data to our user community again.

GN ODB offline Sep 24

    Gemini South Telescope hit by severe earthquake, closed until further notice

    September 17th, 2015

    La Serena was hit by a 8.4 earthquake last night at 19:54 local time, with epicenter 150km from La Serena. Fortunately the staff at the summit and all staff in La Serena are all fine. A first check of the telescope and installations where done after the quake and nothing obvious was seen, but it was decided to cancel the night. A thorough inspection of the telescope on the day after the earthquake it was found that the telescope has shifted on the azimuth platform. The telescope will remain closed over the weekend and the following week, and thus the GEMS/GSAOI run is canceled.
