The Brown Lunation Numbering (BLN) Standard

Introduced by Ernest William Brown in his monumental 1923 treatise Tables of the Motion of the Moon, the Brown Lunation Number assigns Lunation 1 to the New Moon of January 17, 1923.

In the Lunologium computational atlas, every lunation possesses an immutable orbital fingerprint. Rather than viewing a New Moon as merely a calendar date, the Genome resolves its exact geometric proximity to the lunar perigee, maximum declination excursion, and comparative deltas vs preceding lunations.
