On 22 August 2024, summit staff reinstalled Rubin Observatory's commissioning camera (ComCam) on the telescope. ComCam has previously been on the telescope, but was removed before the installation of the secondary mirror in late July. ComCam ??? a smaller (144 megapixel), simpler version of the full 3200-megapixel LSST Camera ??? is being used for testing activities prior to installing the LSST Camera, anticipated to happen late 2024. In the coming weeks the summit team will install the primary/tertiary mirror, enabling ComCam to produce the first astronomical data from the Simonyi Survey Telescope.
