Solar eclipse of November 4, 2078
# Solar eclipse of November 4, 2078

An annular solar eclipse will occur on Friday, November 4, 2078. 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. The path of annularity will cross Pacific Ocean, South America, and Atlantic Ocean. The tables below contain detailed predictions and additional information on the Annular Solar Eclipse of 4 November 2078.

### Solar eclipses 2076–2079

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 2076–2079 :

| Ascending node | Ascending node | Descending node | Descending node |
| - | - | - | - |
| Saros | Map | Saros | Map |
| 119 | June 1, 2076 Partial | 124 | November 26, 2076 Partial |

| 149 | May 1, 2079 Total | 154 | October 24, 2079 Annular |

### 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 1801 and 2100 :
