An annular solar eclipse will occur at the Moon's ascending node of orbit on Saturday, October 4, 2070, with a magnitude of 0.9731. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide.

Saros 135

It is a part of Saros cycle 135, repeating every 18 years, 11 days, containing 71 events. The series started with partial solar eclipse on July 5, 1331. It contains annular eclipses from October 21, 1511 through February 24, 2305, hybrid eclipses on March 8, 2323 and March 18, 2341 and total eclipses from March 29, 2359 through May 22, 2449. The series ends at member 71 as a partial eclipse on August 17, 2593. The longest duration of totality will be 2 minutes, 27 seconds on May 12, 2431.

Inex series

This eclipse is a part of the long period inex cycle, repeating at alternating nodes, every 358 synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic 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.

Inex series members between 1901 and 2100:
January 14, 1926 (Saros 130)	December 25, 1954 (Saros 131)	December 4, 1983 (Saros 132)
November 13, 2012 (Saros 133)	October 25, 2041 (Saros 134)	October 4, 2070 (Saros 135)
September 14, 2099 (Saros 136)
