Vol I · 2 — Two Separate Lineages
Solar and lunar eclipses belong to separate, independently numbered Saros series. The two events in one eclipse season share a season but not a family — a distinction this chapter establishes as the foundation of honest reading.

Solar Saros and Lunar Saros
[ Your prose here — the astronomical fact that solar and lunar eclipses carry separate Saros numbers. ]
The van den Bergh matrix
[ Your prose here — how George van den Bergh numbered the series using the Saros–Inex matrix, and why the solar and lunar catalogues are independent. ]
Why the distinction matters for interpretation
[ Your prose here — why borrowing a solar family theme for a lunar eclipse is a category error, and what Moonlit Zones does instead. ]
Connections
- Vol I · 1 — The Saros Cycle — The 18-year, 11-day, 8-hour period that brings eclipses back — 223 synodic months, 239 anomalistic months and 242 draconic months chiming together so the Sun, Earth and Moon return to nearly the same geometry.
- Vol I · 3 — The Life of a Lunar Family — A Lunar Saros series is born as a faint eclipse near one of the poles, matures over centuries toward deep total eclipses, and fades back to penumbral near the opposite pole — a life of roughly 1,300 years and seventy or more members.
- The Lunar Nodes — The two points where the Moon’s orbit crosses the ecliptic — the Sun’s apparent path. The ascending (North) node and descending (South) node drift slowly backward through the zodiac, and eclipses can happen only when a New or Full Moon falls near one of them.
