Solar eclipse of March 29, 1903
An annular solar eclipse occurred at the Moon's descending node of orbit between Saturday, March 28 and Sunday, March 29, 1903, 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. 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 and 7.8 days before perigee.
Annularity was visible from China, Russia on March 29, and Northern Canada on March 28. A partial eclipse was visible for parts of Southeast Asia, East Asia, North Asia, Alaska, and Northwestern 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.| March 29 Descending node | April 12 Ascending node |
| Annular solar eclipse Solar Saros 118 | Partial lunar eclipse Lunar Saros 130 |
