An annular solar eclipse occurred at the Moon’s ascending node of the orbit on August 22, 1998. 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. Annularity was visible in Indonesia, Malaysia, Papua New Guinea, Solomon Islands (Bellona Island and Rennell Island) and Vanuatu. Occurring only 5.2 days before apogee (Apogee on August 27, 1998), the Moon’s apparent diameter was 3.6% smaller than average.[1] [2] [3]

Metonic series
The metonic series repeats eclipses every 19 years (6939.69 days), lasting about 5 cycles. Eclipses occur in nearly the same calendar date. In addition, the octon subseries repeats 1/5 of that or every 3.8 years (1387.94 days). All eclipses in this table occur at the Moon's ascending node.
