A Cerulean Moonset over CTIO (B View)

Another night of observing begins at the U.S. National Science Foundation Cerro Tololo International Observatory (CTIO) in the Chilean Andes, a Program of NSF NOIRLab, as the Moon sets below the horizon. The Moon appears massive and with a mysterious yellowish glow as it retreats behind the SMARTS–GSU 0.9-meter Telescope on the left, the SMARTS–GSU 1.5-meter Telescope in the center, and the Víctor M. Blanco 4-meter Telescope on the right.

Another viewpoint as the Moon reached the horizon was featured as an Image of the Week. This photo was taken by Hernán Stockebrand, a NOIRLab Audiovisual Ambassador.
