An annular solar eclipse will occur 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] The annularity will be visible in Saudi Arabia, Qatar, United Arab Emirates, Oman, India, Sri Lanka, Malaysia, Indonesia, Singapore, Northern Mariana Islands, and Guam. Population centers in the path of the annularity include Kozhikode, Coimbatore, Jaffna, Trincomalee, Sibolga, Batam, Singapore, Singkawang and Guam. Cities such as Doha, Madurai, Pekanbaru, Dumai and Kuching will narrowly miss the annular path.

Visibility and viewing[edit]

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

The eclipse will begin in Saudi Arabia about 220 kilometers northeast of Riyadh at 03:43 UT1 and will end in Guam at 06:59.4 UT1. It will reach India near Kannur, Kerala at 03:56 UT1. The shadow will reach the southeast coast of India at 04:04 UT1. Traveling through northern Sri Lanka, it will head into the Bay of Bengal. The next main visible places are Palau (Malaysia), Sumatra and Singapore. It then passes through the South China Sea, it crosses Borneo and the Celebes Sea, the Philippines archipelago and then heads towards the western Pacific. The antumbral shadow encounters Guam at 6:56 UT1 and will rise back into space.[1]

Events and Programmes[edit]

Annular Solar Eclipse Outreach Planning Workshop, Chennai[edit]

A two-day workshop has been conducted by the Institute of Mathematical Sciences, Chennai on 26th December 2019 for institutions and organizations interested in popular science education, to plan outreach activities surrounding the Annular Solar Eclipse in the southern states of India, which will be in the path of the annularity. The workshop was co-organized by The Institute of Mathematical Sciences, Chennai, Public Outreach and Education Committee of the Astronomical Society of India (ASI-POEC) and Vigyan Prasar (DST).[3]

11th Southeast Asia Astronomy Network (SEAAN) Meeting, Singapore[edit]

The 11th SEAAN meeting was held in Singapore from the 26th to the 28th of December 2019, so as to coincide with the annular solar eclipse. The primary purpose of the meeting was to bring together people working in different fields of astronomy and astrophysics from Southeast Asia. Secondary aims included:

  • Facilitating exchange in research findings and educational practices
  • Discussion of astronomy outreach efforts

Plenary talks and poster sessions were held over two days. This unique celebration of astronomy in Southeast Asia was organized by the Physics Department from the National University of Singapore.[4]

Outreach Activities at Jaffna University, Sri Lanka[edit]

Jaffna University in collaboration with other institutions in Sri Lanka planned to conduct eclipse observation camps, research and other other activities on 26 th December 2019. Aim of the program is to create an interest science and mathematics and astronomy in particular. Program was supported by the Ministry of Science, Technology and Research, Sri Lanka. [5]

Eclipses of 2019[edit]

Astronomers Without Borders collected eclipse glasses for redistribution to Latin America and Asia for their 2019 eclipses from the Solar eclipse of August 21, 2017.[6]


Half-Saros cycle[edit]


Solar Saros 132[edit]



  • Followed: Solar eclipse of October 26, 2106

Solar eclipses 2018–2021[edit]

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.[7]

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

Saros 132[edit]

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[edit]

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.[8]
