Catalog # (SE5000) 9501

A total solar eclipse occurred on March 9, 1997. 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, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across the surface of the Earth, while a partial solar eclipse will be visible over a region thousands of kilometres wide.

Unusual gravity variations[edit]

This solar eclipse is somewhat special in the sense that some unexplained gravity anomalies of about 7 \times 10−8 m/s2 during the solar eclipse were observed. Attempts (e.g., Van Flandern–Yang hypothesis) to explain these anomalies have not been able to reach a definite conclusion.[1]

Solar eclipses 1997–2000[edit]

Each member 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.

Saros 120[edit]

It is a part of Saros cycle 120, repeating every 18 years, 11 days, containing 71 events. The series started with partial solar eclipse on May 27, 933 AD, and reached an annular eclipse on August 11, 1059. It was a hybrid event for 3 dates: May 8, 1510, through May 29, 1546, and total eclipses from June 8, 1564, through March 30, 2033. The series ends at member 71 as a partial eclipse on July 7, 2195. The longest duration of totality was 2 minutes, 16 seconds on August 12, 1654.[2]

Series members 55–65 occur between 1901 and 2100:

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).

This series has 21 eclipse events between May 21, 1993 and May 20, 2069.
