GeMS Update

The Gemini Multi-Conjugate Adaptive Optics System (GeMS) was off the Gemini South telescope during the Chilean winter, allowing for work to simplify the use during regular operations. Some new tools and interfaces have been developed, and the reliability of several subsystems was improved. An observing run from September 12–16 was the first time the system was on-sky since the improvement work was completed in June and July, and it was challenged with poor weather and some telescope issues. The latest run began last night (September 23), and showed good progress, closing all adaptive optics loops and taking images with the Gemini South Adaptive Optics imager (GSAOI), despite poor natural seeing.
