A totalsolar eclipseoccurred at the Moon'sascending nodeof orbit on Monday, September 21, 1903,[1][2][3]with amagnitudeof 1.0316. Asolar eclipseoccurs when theMoonpasses betweenEarthand theSun,thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon'sapparent diameteris larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide.

Saros 123[edit]

It is a part ofSaros cycle 123,repeating every 18 years, 11 days, containing 70 events. The series started with a partial solar eclipse on April 29, 1074. It contains annular eclipses from July 2, 1182 through April 19, 1651, hybrid eclipses from April 30, 1669 through May 22, 1705, and total eclipses from June 3, 1723 throughOctober 23, 1957.The series ends at member 70 as a partial eclipse on May 31, 2318. The longest duration of totality was 3 minutes, 27 seconds on July 27, 1813.

Inex series[edit]

This eclipse is a part of the long periodinexcycle, repeating at alternating nodes, every 358synodic months(≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with theanomalistic month(period of perigee). However, groupings of 3 inex cycles (≈ 87 years minus 2 months) comes close (≈ 1,151.02 anomalistic months), so eclipses are similar in these groupings.

In the 19th century:

  • Solar Saros 120: Total Solar Eclipse of 1816 Nov 19
  • Solar Saros 121: Hybrid Solar Eclipse of 1845 Oct 30
  • Solar Saros 122: Annular Solar Eclipse of 1874 Oct 10

In the 22nd century:

  • Solar Saros 130: Total Solar Eclipse of 2106 May 3
  • Solar Saros 131: Annular Solar Eclipse of 2135 Apr 13
  • Solar Saros 132: Hybrid Solar Eclipse of 2164 Mar 23
  • Solar Saros 133: Total Solar Eclipse of 2193 Mar 03

Tritos series[edit]

This eclipse is a part of atritoscycle, repeating at alternating nodes every 135synodic months(≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with theanomalistic month(period of perigee), but groupings of 3 tritos cycles (≈ 33 years minus 3 months) come close (≈ 434.044 anomalistic months), so eclipses are similar in these groupings.
