Solar eclipse of October 2, 2024
# Solar eclipse of October 2, 2024

An annular solar eclipse will occur on October 2, 2024. 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.

Other than Easter Island and a small portion near the southern tips of Argentina and Chile, the path of the eclipse's antumbra will be entirely over the Pacific Ocean. The penumbra will be visible from southern South America, Hawaii and portions of Antarctica. Eclipse magnitude is 0.93261, occurring only 56 minutes before apogee.

### Solar eclipses of 2022–2025

This eclipse is a member of a semester series. An eclipse in a semester series of solar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.

Solar eclipse series sets from 2022–2025 :

### Saros 144

It is a part of Saros cycle 144, repeating every 18 years, 11 days, containing 70 events. The series started with partial solar eclipse on April 11, 1736. It contains annular eclipses from July 7, 1880 through August 27, 2565. There are no total eclipses in the series. The series ends at member 70 as a partial eclipse on May 5, 2980. The longest duration of annularity will be 9 minutes, 52 seconds on December 29, 2168.

### Tritos series

This eclipse is a part of a tritos cycle, repeating at alternating nodes every 135 synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic 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.

Series members between 1901 and 2100 :

| September 9, 1904 (Saros 133) | August 10, 1915 (Saros 134) | July 9, 1926 (Saros 135) |

### Metonic cycle

The metonic series repeats eclipses every 19 years (6939.69 days), lasting about 5 cycles. Eclipses occur in nearly the same calendar date. In addition, the octon subseries repeats 1/5 of that or every 3.8 years (1387.94 days). All eclipses in this table occur at the Moon's descending node.

21 events between July 22, 1971 and July 22, 2047 :
