Solar eclipse of June 17, 1909


A total solar eclipse occurred at the Moon's ascending node of orbit between Thursday, June 17 and Friday, June 18, 1909, with a magnitude of 1.0065. It was a hybrid event, with a long section of its path as total, and smaller sections at the start and end as an annular eclipse. 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. The Moon's apparent diameter was near the average diameter because it occurred 5.4 days after perigee and 7.5 days before apogee.
The path of totality crossed central Russia, the Arctic Ocean, northeastern Ellesmere Island in Canada, Greenland, and annularity crossed southern Siberia in Russia and southern Greenland. A partial eclipse was visible for parts of East Asia and northern North America.

Eclipse season

This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight.
