On the Daytime Use of Dome C for Astronomy
Department of Astronomy, University of Washington, Seattle,

I describe aspects of the non-solar astronomy use of Dome C telescopes under daytime/summer conditions. In the thermal IR (TIR) wavelength region, where scattered sunlight is dwarfed by sky and facility radiation, astronomy benefits from the better seeing, continuous sky coverage, a more than doubling of the observing time and the improved site accessibility and logistics. Na-Laser Guide Stars (LGSs) can be used for wavefront sensing in daytime using very narrow band filters to suppress the sky background at visible wavelengths. It enables the use of Adaptive Optics for diffraction limited imaging in the TIR during daytime at Dome C.
