An annular solar eclipse occurred at the moon's descending node of its orbit on Tuesday, May 10, 1994. It was visible over a wide swath of North America, from Baja California across the Midwest of the United States up through Ontario and Nova Scotia in Canada. Occurring only 1.6 days after apogee (Perigee on Monday, May 9, 1994, at 02:18 UTC or Sunday, May 8, 1994, at 22:18 EDT or 19:18 PDT), the moon's apparent diameter was smaller than the sun. This solar eclipse belonged to Saros series 128.

The annular eclipse of May 10, 1994[edit]

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. If the eclipse is a central one, it will be either total, annular or a combination of both, called a hybrid eclipse. In a total eclipse, the moon's size as seen from earth is large enough to block all of the disk of the sun.

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), which means there is a ring of light from the sun around the dark moon. An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide.

The path of annularity crossed four states of Mexico (Baja California Sur, Baja California, Sonora and Chihuahua), the United States, the Canadian provinces of Ontario, Nova Scotia and the southeastern tip of Quebec, Azores Islands except Santa Maria Island, and part of Morocco including the capital city Rabat. Niagara Falls was also covered by the path of annularity.

The eclipse reached its moment of "greatest eclipse" in the United States near Wauseon, Ohio, about 35 miles west of Toledo, Ohio.

The Columbus Crew were originally named the "Columbus Eclipse" in their Major League Soccer bid in honor of the event.^[1]

Solar eclipses 1993–1996[edit]

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.^[2]

Saros 128[edit]

This eclipse is a member of the Solar Saros cycle 128, which includes 73 eclipses occurring in intervals of 18 years and 11 days. The series started with partial solar eclipse on August 29, 984 AD. From May 16, 1417, through June 18, 1471, the series produced total solar eclipses, followed by hybrid solar eclipses from June 28, 1489, through July 31, 1543, and annular solar eclipses from August 11, 1561, through July 25, 2120. The series ends at member 73 as a partial eclipse on November 1, 2282. All eclipses in this series occurs at the Moon's descending node.

Inex series[edit]

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.

Inex series members between 1901 and 2100:
July 10, 1907 (Saros 125)	June 19, 1936 (Saros 126)	May 30, 1965 (Saros 127)
May 10, 1994 (Saros 128)	April 20, 2023 (Saros 129)	March 30, 2052 (Saros 130)
March 10, 2081 (Saros 131)

Metonic cycle[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). All eclipses in this table occur at the Moon's descending node.
