A total solar eclipse occurred at the Moon's descending node of orbit on Wednesday, June 30, 1954,[1] with a magnitude of 1.0357. 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. A total solar eclipse occurs when the Moon's apparent diameter is 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. Occurring about 3.1 days after perigee (on June 27, 1954, at 11:10 UTC), the Moon's apparent diameter was larger.[2]
Visibility
Totality began at sunrise over the United States over Nebraska, South Dakota, Minnesota, and Wisconsin, and crossed into Canada, across southern Greenland, Iceland and Faroe Islands, then into Europe, across Norway, Sweden, and eastern Europe.[3] It ended before sunset over Iran, Afghanistan, Pakistan, and ending in northwestern India. The southwestern part of Vilnius, northeastern part of Kyiv, and southwestern part of Baku were covered by the path of totality.
The northeastern part of Mount Elbrus, the highest mountain in Europe, also lay in the path of totality.
The eclipse was mostly seen on June 30, 1954, except for northeastern Soviet Union, where a partial eclipse started on June 30, passing midnight and ended on July 1 due to the midnight sun.
A partial eclipse was visible for parts of eastern North America, Europe, North Africa, West Asia, Central Asia, and South Asia.
Observation
Within the United Kingdom, the path of totality only covered Shetland Islands in northern Scotland. However, the area was mostly clouded out during the eclipse, and there was even light rain in some places, so observation was not successful. About 400 scientists from around the world traveled to Sweden to observe the total eclipse.[4] The Astronomy Department of Kiev State University, Soviet Union made observation in Kyiv and took ideal images of solar corona. The Sternberg Astronomical Institute made observation in Nevinnomyssk, Stavropol Krai.[5]
In Wakefield, Massachusetts, U.S., the eclipse was blocked by heavy cloud cover from 6 to 8 a.m. local time, The Wakefield Daily Item reported.[6]

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.

Solar eclipses of 1953–1956
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.[8]
The partial solar eclipses on February 14, 1953 and August 9, 1953 occur in the previous lunar year eclipse set.

Saros 126
This eclipse is a part of Saros series 126, repeating every 18 years, 11 days, and containing 72 events. The series started with a partial solar eclipse on March 10, 1179. It contains annular eclipses from June 4, 1323 through April 4, 1810; hybrid eclipses from April 14, 1828 through May 6, 1864; and total eclipses from May 17, 1882 through August 23, 2044. The series ends at member 72 as a partial eclipse on May 3, 2459. 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 was produced by member 11 at 6 minutes, 30 seconds on June 26, 1359, and the longest duration of totality was produced by member 45 at 2 minutes, 36 seconds on July 10, 1972. All eclipses in this series occur at the Moon’s descending node of orbit.[9]

Metonic series
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.

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.
