Astronomical Sunrise is considered as the time when the upper limb (the edge of the Sun and the Moon) of the Sun appears for the first moment. Similarly, the Sunset is the time of disappearance of the upper limb of the Sun. While, astrologically, Sunrise is the time when the Sun’s Madhyalimb or middle disk rises above eastern horizon. In addition, Vedic astrology ignores the refraction of the Sun rays.
