I need to find historical data for moon phases in the third century BCE

[bjdbowman]

can anyone point me to a database where i can query the moon phases for years that i can cite in my work? I am finding varying data all over the place. I have CyberSky application which works good for basic data but i need to verify the data with another source. Please can anyone help me in finding data. Is there a data source for Stellarium that can quired and cited? let me know. Thanks.

Lunar phases are not store in databases but computed from ephemeris models.

All models used by Stellarium are documented in the User Guide. Information about historical accuracy and usability for research is found in Appendix F.

is it possible to create a script to query and list the dates of the moon phases for specific years? Is the data available online to query via AI? Please let me know.

[gzotti]

Yes. No. Welcome.

that was quick, thank you. I am not a software programmer. I am just working on a personal project. Would it be okay to ask the community if someone would help me by creating a script to extract the data that I need? i appreciate your time, and have a great day.

[gzotti]

Sure. Anyone willing to write such script?

[bjdbowman]

Thanks... But, I have found the source material that you base your calcs on... and I now have the data that I need. Thanks.
