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.

False-colour scanning electron micrograph of skin from the palm of the hand of a 30 year old man. The skin here is neatly arranged in ridges. Sweat pores are seen as miniature craters along the ridges. The cells forming the external surface of the skin, or epidermis, have been flattened & hardened by deposition within them of the fibrous protein keratin. This tough, dead layer of cells is shed continuously & is replaced by new, maturing cells which take a month to migrate from the base of the epidermis. Magnification: x20 at 6x4.5cm size

Forget aesthetics, the reason to look after our skin should be health
