Saros Cycle & Eclipse Magnitude Formula
Saros = 223 synodic months = 18 yr, 11 d, 8 hrEclipses in the same Saros series recur every Saros period at almost the same Sun-Moon-Earth geometry. Each series spans about 1,200-1,500 years through ~70 eclipses.
M_solar = (s_moon + r_moon − |gap|) / (2 r_sun)Where s_moon, s_sun are the angular semi-diameters and |gap| is the Moon-Sun center separation. M ≥ 1 = total; 0 ≤ M < 1 = partial; M ≥ 1 with Moon at apogee = annular (ring of fire).

How To Plan Eclipse Travel
- 1. Browse the catalog table and filter by Solar/Lunar/Total to narrow.
- 2. Click "View" on a row to load that eclipse into the SVG widget.
- 3. Note the duration in seconds and the broad region for travel planning.
- 4. Cross-reference the Saros series number with NASA's GSFC catalog for sub-km path precision.
- 5. Save the eclipse — your list persists locally so you can revisit travel ideas.
Eclipse Prediction — From Babylonian Tablets To NASA GSFC
In 2026, a Munich-based eclipse-tour operator is selling Iceland and Spain seats for the August 12 total solar eclipse. The path she books crosses Akureyri in northern Iceland with 2 minutes 12 seconds of totality. The arithmetic that pinpointed that path to within kilometers — three years in advance — descends from clay tablets impressed by Babylonian scribes 2,700 years ago.
Babylonian astronomers at the Esagila temple (Babylon, ~700-300 BCE) recorded systematic lunar and solar eclipse observations on cuneiform tablets in the Astronomical Diaries series. They identified the Saros cycle — 223 synodic months (18 yr, 11 d, 8 hr) after which Sun, Moon, and Earth return to nearly identical relative geometry. The British Museum holds 1,600+ Babylonian eclipse records; the May 28, 585 BCE solar eclipse over Asia Minor (predicted by Thales of Miletus and confirmed by Herodotus' Histories 1.74) is the first firmly dated event in human history.
Tycho Brahe (1546-1601) brought eclipse-position measurement to arc-minute accuracy at Uraniborg. Johannes Kepler(1571-1630) used Brahe's data to publish Astronomia Nova (1609) and Harmonices Mundi (1619), establishing the elliptical-orbit laws. Kepler's 1605 prediction of the eclipse path across central Europe was the first quantitatively accurate forecast in history. Isaac Newton(Principia, 1687) provided the gravitational physics; Edmond Halley first published precise eclipse path maps in his 1715 chart of the May 3 total solar eclipse over England.
The modern gold standard is the NASA Goddard Space Flight Center Eclipse Catalog, computed by Fred Espenak(1953-) and Jean Meeus over four decades. It catalogs every eclipse from 2000 BCE through 3000 CE with sub-second timing and sub-km path precision. Espenak's Five Millennium Canon of Solar Eclipses (NASA TP-2006-214141) is the reference cited in every eclipse-planning tool — including this one.
Saros series rotation is one of the most beautiful patterns in astronomy. The August 12, 2026 total solar eclipse is Saros 126 member 48 of 72 — the previous eclipse in this series (Aug 1, 2008) crossed Siberia; the next (Aug 23, 2044) will cross Greenland and North America. Each Saros eclipse shifts about 120° west longitude, completing a global rotation every 3 Saros cycles (~54 years), the "exeligmos" the Babylonians also identified.
Eclipse science continues to advance: total solar eclipses provide the only opportunity to image the Sun's corona (1 part in a million of the photosphere's brightness) from Earth's surface; the 1919 Eddington expedition during a total solar eclipse confirmed Einstein's general relativity. Modern solar physicists use the August 2, 2027 eclipse (6m 23s totality) for coronal heating research.
Combine with moon phase, planet visibility, and solar noon.
Eclipse-Tour Operators & Astronomers
“I cross-reference NASA's catalog every time I plan a trip. Having the Saros number alongside the magnitude and duration on a single page is a planner's dream. Booked Iceland for Aug 12 the day I found this.”
“I run a 200-member observation group. Our club uses this calendar to coordinate observation evenings out to 2030. The clean region descriptions help us decide which eclipses are worth a club trip.”
“I sell tours to totality paths and this is the cleanest cross-reference of the 2026-2030 window I've found online. The duration-in-seconds field is what my customers ask first.”
“I lecture on eclipse mechanics to families and use the moon-passing-sun SVG as my opening slide. The Saros pattern across the table makes the 18-year cycle obvious without saying a word.”
