摘要: A selected group of measurements the sky brightness during total solar eclipses is used to determine a standard light curve period from no obscuration totality. It found that may be considered as attenuated sunlight up at least 99.8% obscuration. During totality, consists multiply scattered outside umbral region. The effects elevation angle, cloud cover, and albedo variability totality are discussed.
