The Vera C. Rubin Observatory is built in Chile, designed to be a 10 year survey to study various science fields from solar system to the dark matter and dark energy. It’s still under a construction and on the commissioning phase. Until the first light, we have to build and test every parts of the telescope, to operate safer, to get better quality of images, and to make astronomical measurements more precise to study the Universe. I will briefly introduce the observatory and what we do during the commissioning.
In April we have finished our testing with mirror surrogates and commissioning camera before installing the real glass mirrors. LSSTCam arrived to the summit and will be tested in the clean room before installation. We are looking for first on-sky image testing with commissioning camera and real mirrors soon in a month. I will introduce tests we have done, and few examples of analysis done to make sure all the components are working well or to make them better.
