# Solar eclipse of July 1, 2057

An annular solar eclipse will occur at the Moon's ascending node of orbit between Sunday, July 1 and Monday, July 2, 2057, with a magnitude of 0.9464. 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. Occurring about 1.7 days after apogee (on June 30, 2057, at 6:30 UTC), the Moon's apparent diameter will be smaller.
The path of annularity will be visible from parts of northwest China, Mongolia, eastern Russia, northern Alaska, western and central Canada, and far northeast Minnesota, northern Michigan, and far western New York in the United States. A partial solar eclipse will also be visible for parts of East Asia, Northeast Asia, Northern Europe, and North America.

## Eclipse season

This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight.
Eclipse season of June–July 2057 :
| June 17 Descending node (full moon) | July 1 Ascending node (new moon) |
| Partial lunar eclipse Lunar Saros 121 | Annular solar eclipse Solar Saros 147 |

### Solar eclipses of 2054–2058

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.
The partial solar eclipses on March 9, 2054 and September 2, 2054 occur in the previous lunar year eclipse set, and the partial solar eclipses on May 22, 2058 and November 16, 2058 occur in the next lunar year eclipse set.
Solar eclipse series sets from 2054 to 2058 :

### Saros 147

This eclipse is a part of Saros series 147, repeating every 18 years, 11 days, and containing 80 events. The series started with a partial solar eclipse on October 12, 1624. It contains annular eclipses from May 31, 2003 through July 31, 2706. There are no hybrid or total eclipses in this set. The series ends at member 80 as a partial eclipse on February 24, 3049. Its eclipses are tabulated in three columns; every third eclipse in the same column is one exeligmos apart, so they all cast shadows over approximately the same parts of the Earth.
The longest duration of annularity will be produced by member 38 at 9 minutes, 41 seconds on November 21, 2291. All eclipses in this series occur at the Moon’s ascending node of orbit.

### 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 2200 :
| June 16, 1806 (Saros 124) | May 16, 1817 (Saros 125) | April 14, 1828 (Saros 126) | March 15, 1839 (Saros 127) | February 12, 1850 (Saros 128) |

### 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.
Series members between 1801 and 2200 :
