Solar eclipse of February 16, 1999
An annular solar eclipse occurred at the Moon's descending node of orbit on Tuesday, February 16, 1999, with a magnitude of 0.9928. 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 7.9 days after apogee and 4.3 days before perigee.
Annularity was visible in the southern Indian Ocean including the Prince Edward Islands, South Africa, and Australia. A partial eclipse was visible for parts of Southern Africa, Antarctica, Australia, Indonesia, the Philippines, and western Oceania.
The date of this eclipse was the exact day of Lunar New Year, celebrated in places including Southeast Asia, where a partial eclipse was visible.

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.| January 31 Ascending node | February 16 Descending node |
| Penumbral lunar eclipse Lunar Saros 114 | Annular solar eclipse Solar Saros 140 |
