A partial solar eclipse occurred at the Moon's descending node of orbit between Saturday, January 5 and Sunday, January 6, 2019,[1] with a magnitude of 0.7145. 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 partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth.
The eclipse was visible in Northeast Asia and southwestern Alaska.
The maximal phase (71%) of the partial eclipse was recorded in Sakha Republic (Russia).
The eclipse was observed in Japan, the Russian Far East, North and South Korea, eastern China, eastern Mongolia and northwest Alaska.
Shown below are two tables displaying details about this particular solar eclipse. The first table outlines times at which the moon's penumbra or umbra attains the specific parameter, and the second table describes various other parameters pertaining to this eclipse.[2]

See also: Eclipse cycle. This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) 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.
