Heliacal rising

Heliacal rising occurs when a celestial object, such as a star or planet, first becomes visible just before sunrise after a period of being hidden by the Sun's glare. This event marks the object's emergence from the Sun’s direction as seen from Earth, often after a conjunction. Historically significant, heliacal risings have been used to mark seasonal changes and agricultural cycles. The timing varies based on the observer’s location and the specific object’s orbit, making it an important concept in astronomy and cultural traditions.
