A total solar eclipse occurred on July 22, 1990. 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.
In Finland the solar eclipse occurred during sunrise and enabled observation and photography without protective glasses, which was however hampered by strong clouds.[1] The Sun was totally eclipsed in Helsinki began at 06:03:07 local time.
