Sawai Jai Singh II’s astronomical observatories and anomalous-sky interpretation

Record summary

Maharaja Sawai Jai Singh II established large masonry observatories and commissioned the Zij-i Muhammad Shahi to improve astronomical measurement. These institutions provide a concrete context for testing how unusual celestial sightings were recorded, classified, or excluded in early eighteenth-century India. They are not encounter reports themselves. Researchers can compare instrument capabilities, tables, and court records with later claims that premodern observers saw unexplained aerial objects. The relevant uncertainty is which local observing logs survive and how fully they have been edited.
