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. The Sun was totally eclipsed in Helsinki.
