Solar eclipse of March 29, 1903
Template:Short description Script error: No such module "Solar eclipse". An annular solar eclipse occurred at the Moon's descending node of orbit between Saturday, March 28 and Sunday, March 29, 1903,[1][2][3] with a magnitude of 0.9767. 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. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. The Moon's apparent diameter was near the average diameter because it occurred 6.7 days after apogee (on March 22, 1903, at 8:40 UTC) and 7.8 days before perigee (on April 5, 1903, at 18:40 UTC).[4]
Annularity was visible from China (now northwestern China, Mongolia and northeastern China), Russia on March 29 (Sunday), and Northern Canada on March 28 (Saturday). A partial eclipse was visible for parts of Southeast Asia, East Asia, North Asia, Alaska, and Northwestern North America.

Eclipse season
Script error: No such module "Labelled list hatnote". 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.

Solar eclipses of 1902–1906
This eclipse is a member of a semester series. An eclipse in a semester series of solar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.[6]
The partial solar eclipses on May 7, 1902 and October 31, 1902 occur in the previous lunar year eclipse set, and the partial solar eclipse on July 21, 1906 occurs in the next lunar year eclipse set.
