On This Day - July 11th 1991
A solar eclipse is observed stretching from Hawaii to South America, and lasting up to 7 minutes in some areas.
A solar eclipse occurs when the moon passes between the Earth and the Sun, casting its shadow over the Earth. The 11 July 1991 eclipse was observed best by scientists in observatories atop Mauna Kea in Hawaii. First contact (when the moon first began its progression across the face of the sun) occurred at 6:30am, and totality (total coverage of the sun) began at 7:28. The longest eclipse for the next 141 years, totality lasted 6 minutes and 52 seconds on the centreline on the Baja peninsula of Mexico.
