# Moon and Sun UV Light

How much ultraviolet light comes from the moon at night and from the Sun during the day? I am interested in using a UV camera on a robot to see the UV from the sun/moon to do robot localization.

• "How much" is rather ambiguous. Do you have a wavelength range you're interested in? Are you looking for a $W m^{-2}$ type answer? Even still, this will be highly variable depending on physical location on Earth, weather, altitude, time of day, etc. I think you need to provide more specific parameters concerning what it is you want or you're trying to do.
