We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

Saros (astronomy) — The entry states that the saros corresponds to 'nearly 242 draconic months' and lists 'draconic_months=241.999', but the widely accepted value is exactly 242 draconic months, not 241.999.
Saros (astronomy) — The entry lists 'eclipse_years=18.999' and 'years=18.029'. The saros is approximately 18 years 11 days 8 hours, which is about 18.030 years, not 18.029.
Selenography — The claim that Johann Heinrich von Mädler published the first large cartograph map of the Moon in 1834–1836 is misleading; the map was co-authored with Wilhelm Beer and published as 'Mappa Selenographica' in 1834–1836, not solely by von Mädler.
Selenography — The claim that Clementine produced the first nearly global topographic map of the Moon using laser altimetry is inaccurate; Clementine's laser altimeter covered only about 80% of the lunar surface, and the first nearly global topographic map was produced by th
Sky brightness — The total night sky brightness value 'm=~250 S10 (equivalent to ~22.0 mag/arcsec²)' is factually incorrect; typical dark zenith sky brightness of 250 S10 corresponds to approximately 21.6–21.8 mag/arcsec², not 22.0.
Sky brightness — The statement that light pollution was estimated in 2023 to be rising at 9.6% per year is misleading; the 9.6% figure is from a 2016 study, not a 2023 estimate.
