Solar eclipse of December 26, 2019

An annular solar eclipse occurred on December 26, 2019. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring 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.[1]

Visibility and viewing
Animated path

It was the last solar eclipse of 2019. The central path of the 2019 annular eclipse passed through Saudi Arabian Peninsula, southern India, Sumatra, Borneo, Philippines and Guam. A partial eclipse was visible thousands of kilometers wide from the central path. It covered small parts of Eastern Europe, much of Asia, North/West Australia, East in Africa, Pacific and Indian Ocean.[1][2] The eclipse started with an antumbra having a magnitude of .96; it stretched 164 kilometers wide, and traveled towards the east at an average rate of 1.1 kilometer per second. The longest duration of annularity was 3 minutes and 40 seconds, at 5.30 UT1 occurring in the South China Sea (0°45'54.0"N 105°29'06.0"E).[1]

The eclipse began in Saudi Arabia about 220 kilometers northeast of Riyadh at 03:43 UT1 and ended in Guam at 06:59.4 UT1. It reached India near Kannur, Kerala, at 03:56 UT1. The shadow reached the southeast coast of India at 04:04 UT1. Traveling through northern Sri Lanka, it headed into the Bay of Bengal. The next main visible places were Palau (Malaysia), Sumatra and Singapore. It then passed through the South China Sea, crossed Borneo and the Celebes Sea, the Philippines archipelago and then headed towards the western Pacific. The antumbral shadow encountered Guam at 6:56 UT1 and rose back into space.[1]

Solar eclipses 2018–2021

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.[4]

Note: Partial solar eclipses on February 15, 2018, and August 11, 2018, occurred during the previous semester series.

Saros 132

This eclipse is a part of Saros cycle 132, repeating every 18 years, 11 days, containing 71 events. The series started with partial solar eclipse on August 13, 1208. It contains annular eclipses from March 17, 1569 through March 12, 2146, hybrid on March 23, 2164 and April 3, 2183 and total eclipses from April 14, 2200 through June 19, 2308. The series ends at member 71 as a partial eclipse on September 25, 2470. The longest duration of annular was 6 minutes, 56 seconds on May 9, 1641, and totality will be 2 minutes, 14 seconds on June 8, 2290. All eclipses in this series occurs at the Moon’s descending node.

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 descending node.[5]
