Assyrians record a solar eclipse that is later used to fix the chronology of Mesopotamian history.

Assyria was a major ancient Mesopotamian civilization that existed as a city-state from the 21st century BC to the 14th century BC and eventually expanded into an empire from the 14th century BC to the 7th century BC.

The Assyrian eclipse, also known as the Bur-Sagale eclipse, was a solar eclipse recorded in Assyrian eponym lists that most likely dates to the tenth year of the reign of king Ashur-dan III. The eclipse is identified with the one that occurred on 15 June 763 BC in the proleptic Julian calendar.

Chronology is the science of arranging events in their order of occurrence in time. Consider, for example, the use of a timeline or sequence of events. It is also "the determination of the actual temporal sequence of past events".

Mesopotamia is a historical region of West Asia situated within the Tigris–Euphrates river system, in the northern part of the Fertile Crescent. It corresponds roughly to the territory of modern Iraq. and forms the eastern geographic boundary of the modern Middle East. Just beyond it lies southwestern Iran, where the region transitions into the Persian plateau, marking the shift from the Arab world to Iran. In the broader sense, the historical region of Mesopotamia also includes parts of present-day Iran (southwest), Turkey (southeast), Syria (northeast), and Kuwait.

June 15 is the 166th day of the year in the Gregorian calendar; 199 days remain until the end of the year.
