A total solar eclipse occurred on Tuesday, January 25, 1944. 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. Totality was visible from Peru, Brazil, British Sierra Leone (today's Sierra Leone), and French West Africa (the parts now belonging to Guinea, Mali, Burkina Faso and Niger, including Guinean capital Conakry). At greatest eclipse, the Sun was 78 degrees above horizon (just 12 degrees from zenith).

Observations[edit]

The National Astronomical Observatory in Tacubaya, Mexico sent a team to Chiclayo, Peru. The weather was clear during the eclipse, and because totality occurred shortly after sunrise with a relatively low solar zenith angle, the boundary between the corona and the background of the sky was not so obvious. Most images were taken successfully except for one with the long focus camera.[1]

Saros 130[edit]

This eclipse is a part of Saros cycle 130, repeating every 18 years, 11 days, containing 73 events. The series started with partial solar eclipse on August 20, 1096. It contains total eclipses from April 5, 1475 through July 18, 2232. There are no annular eclipses in the series. The series ends at member 73 as a partial eclipse on October 25, 2394. The longest duration of totality was 6 minutes, 41 seconds on July 11, 1619. All eclipses in this series occurs at the Moon’s descending node.[3]

Metonic series[edit]

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).
