tive cross-training program with other AURA centers in Chile. New Archive Imminent! The new Gemini Observatory Archive will be launched in October. Developed in-house as a project led by Observatory Scientist Paul Hirst, the user interface is quite different from the archive at the Canadian Astronomy Data Centre (CADC) which it replaces. However, one of the most significant changes is “under the hood”. The archive is now being hosted by Amazon Web Services and stored on the Cloud. This cost-effective solution is well suited to our globally distributed user community. The change is imminent, so keep watching! GRACES First Science GRACES has moved from development into operations; see the article by André-Nicolas Chené on the commissioning and first science data, starting on page 14 of this issue. Figures 4. Data from the Gemini South secondary mirror sensors at the time of the September 16th earthquake. Gemini South and the Chilean Earthquake As you’re probably aware, Gemini South was affected by the large (magnitude ~8.3) earthquake which struck Chile on September 16th. At the time of the quake, Gemini South was closed due to sever weather (see news item above). Since systems were powered up, the secondary mirror system effectively acted as a seismometer. The picture here shows the secondary oscillations in response to the early arriving P waves, followed some 20 seconds later by the major shock of the main quake. As this issue goes to e-press Gemini South is almost completely recovered from the earthquake, and is back on the sky doing normal science operations. October 2015 GeminiFocus 24
