8th NOV 2022 - LAST TOTAL LUNAR ECLIPSE TILL 2025
(Between 8 Nov 2022 and Sept 2025 – Five Lunar Eclipses will occur – People in India have to wait till 7 Sept 2025 to see a Total Lunar Eclipse - Lunar Eclipse occurring on 28 Oct 2023 visible in India is Partial)
On 8th November 2022 a Total Lunar Eclipse will occur. This is the last Eclipse of year, among four eclipses for year 2022. Though this eclipse is a Total Lunar Eclipse, totality is visible only in East or North Eastern state of India based on Moon rise timings before 5.12 p.m. Whereas rest of India would see the eclipse partially till 6.19 p.m.
The duration of eclipse and percentage of Moon’s disk covered for an observer would depend on rising timings of moon at various locations in India. As Eclipse begins before Moon Rise for people India, we will miss the beginning phase of Eclipse. However people will witness the end of eclipse with Moon slowly leaving the darker shadow of earth by 6.19 p.m.
Across the world visibility of the eclipse is dependent on timings of Moon Rise or Moonset. In few countries people will see eclipse at time when Moon is setting in their location. Example North/South American countries. Which means people in these countries would see only beginning of eclipse. Whereas at other places people will see eclipse at time when Moon is rising. Example: For people in India & other countries in Asia. Eclipse would begin before Moon rise and they will see the end of eclipse. However, people only in few places across the world would witness the totality of the moon either at Beginning or End of Totality Phase (like east and north east parts of India). This eclipse will be visible in the region covering South America, North America, Australia, Asia, North Atlantic Ocean, and Pacific Ocean.
The Last Lunar Eclipse visible in India occurred on 19 November, 2021 which was Longest Partial Lunar Eclipse in 580 Years. As recorded by NASA from New Orleans the duration of Partial Eclipse on 19 November 2021 was for 3hrs 28 Min 24 Sec. Whereas the Next Eclipse visible from India which is Partial Lunar Eclipse will occur on night of 28th and 29th October in 2023.
Timings of Eclipse in Indian standard Time on 8th Nov 2022: Eclipse in various phases begins at 1.30p.m IST and ends at 7.28pm IST. However, the noticeable Umbral phase begins at 2.39 p.m. IST and Ends at 06.19 p.m. IST. In other words, though astronomically speaking Eclipse begins at 1.30 p.m. with moon entering lighter Shadow of Earth. People can noticeably witness darkening or leaving of Moon’s disk by Earth Shadow between 2.39 p.m IST to 6.19 p.m. IST on 8th November, 2022. Whereas the Totality Phase when Moon’s disk is completely immersed in Dark shadow of Earth starts at 3.46 p.m. and ends at 5.12 p.m.
Next Total Lunar Eclipse in 2025 – East, North East Best Place for 8 Nov 2022: Here is the list of Lunar Eclipses after 8 Nov 2022. (1). 5 May 2023 – Penumbral Lunar Eclipse, (2). 28 Oct 2023 – Partial Lunar Eclipse (visible in India) (3). 25 March 2024 - Penumbral Lunar Eclipse (4). 18 Sept 2024 – Partial Lunar Eclipse (5). 14 March 2025 – Total Lunar Eclipse (not visible in India) (6). 7th Sept 2025 – Total Lunar Eclipse (visible in India). Which means there are five Lunar Eclipse occurring in next three years and the next Total Lunar Eclipse will only occur in 2025. Hence people should not miss the Lunar Eclipse on 8 Nov 2022. Whereas on 8th Nov 2022, people visiting or staying in Eastern or Northern Eastern parts of India will get best opportunity to see entire disk of Moon immersed in dark shadow of Earth.
Eclipse for People In Telugu States – Partial – till 6.19 p.m. – Percentage – What to expect: Though visible umbral phase of Eclipse starts at 2.39 p.m. before Moonrise. People in Hyderabad can see the eclipse from 5.40 p.m. in Telangana. For Vijayawada in A.P. it’s from 5.33p.m. Whereas people in Rajahmundry will be first to see the eclipse from 5.25p.m. It’s important to note people in north and north eastern parts of both states would be first to witness the eclipse compared to Western or Southern parts. Duration and Percentage of Lunar Eclipse visible is be based on rising time of Moon in their location. On 8 Nov 2022 as Totality phase is already over at 5.12 p.m. before moon rises here. People would miss entire disk of Moon immersed in Earth shadow. They would however see Moon a portion of Moon eclipse as Moon rises in East. Importantly people here would witness Moon leaving earth’s dark shadow by 6.19 p.m.
FOR PLANETARY SOCIETY OF INDIA (PSI), Director, N.Sri Raghunandan Kumar .
PSI celebrated 20th establishment day ceremony on 17th Oct 2022.
1. A Lunar Eclipse: occurs when earth in course of its orbit around sun, comes between moon and sun such a
way that moon his hidden in the shadow cast by earth. This can occur only when the Sun, Earth, and Moon are
aligned in a straight line. Hence lunar eclipse occurs only when there is full moon.
2. Penumbra and Umbra: Earth’s shadow has two parts Penumbra (outer lighter part) and Umbra (darker
part). All Lunar Eclipse begin with moon first entering penumbra at one end passing through umbral phase and
ending with Leaving the penumbra on other end.
Generally only the Umbra phase is commonly considered as actual eclipse by General public to follow various rituals and traditions leaving Penumbra passage of moon. Whereas scientifically speaking all Lunar Eclipse begin and end with moon entering and leaving the penumbra (lighter outer shadow of earth).
3. Totality in East and North Eastern States – Rest of India Partial: In India Agartala, Aizawl, Bhagalpur, Bhubaneswar, Cooch Behar, Cuttack, Darjeeling, Dibrugarh, Gangtok, Guwahati, Gaya, Hazaribagh, Imphal, Itanagar, Kohima, Kolkata, Midnapore, Murshidabad, Muzaffarpur, Patna, Port Blair, Puri, Ranchi, Shillong, Sibsagar, Silchar, Siliguri, Tamelong, Varanasi, Chittagong are the places where the people can witness the Moon full eclipsed in Earth’s dark shadow towards end of the Totality phase ie. 5.12p.m. Whereas rest of the country people can witness the eclipse in partial phase only with a portion of Moon Disk eclipsed.
4. First & Last Places to see Eclipse on 8th Nov 2022 – Depends on Moon rise time on 8th Nov : People in Eastern or North Eastern most parts of India like Dibrugarh will be the first to see the eclipse on 8th November starting 4.17p.m. In India. They will see the Moon completely immersed in dark shadow of earth as the Totality phase already started at 3.46p.m. Whereas people in Itanagar & Kohima will see the eclipse starting from 4.24p.m. People in Northern most parts of India like ladakh will see eclipse from 5.17p.m.
People in Central part of India like in Bhopal would start seeing the eclipse from 5.36p.m. Whereas people in Southern most part of India i.e. Kanyakumari will witness the eclipse from 5.57p.m. In Kavaratti (Lakshadweep) eclipse is visible from 6.11 p.m. People in Western most parts of India like in Dwaraka will be last to witness the eclipse from 6.12 p.m. for just 7mins before end of Umbral Phase at 6.19p.m. Here people will see a very small part of Moon Disk eclipsed. This means duration of the eclipse and percentage of Moon disk eclipsed would differ as we move from East or North parts towards Western and Southern part of India depending on rising time of moon for a location.
5. Pregnant Woman – Superstitious Restrictions – Food Spoilage – Govt & WHO: During eclipse various restrictions in the form of rituals based on misunderstanding of Eclipse are imposed on Pregnant ladies in India. Cleft lip and cleft palate which is a medical condition is wrongly associated with Eclipse as after effect in unborn kids. If Eclipses were harmful to pregnant women, unborn kids the World Health Organization (WHO) would have issued medical advisory to nations. At least, Ministry of Health & Family Welfare in India would have warned people since last 70 years. Further regarding food, if it was to be spoiled by eclipse, Food Safety and Standards Authority of India (FSSAI), CSIR organisations would have warned people.
Whereas Science organizations, Government bodies do issue instructions regarding solar eclipse as Sun shouldn’t be viewed directly or through binoculars or x-ray films. But only through solar filters or Grade 14 Welder Glass and indirect methods. However astrologers are misinterpreting these instructions and spreading various myths, superstitions creating fear in the people against eclipses. Further a Lunar Eclipse can be seen directly with bare eyes.
Now that there is widespread superstition on the issue of Food, Pregnant Women, travel during eclipses. Govt of India should issue special instructions and also prevent superstitious ideas being spread using social media. It should instruct state governments to take special steps to prevent Naraballi (Human Sacrifice) incidents prevalent during eclipses.
6. Social Media misinformation: Its fact that we see phases of Moon in span of 30 days (New moon to full moon and back to New Moon). I.e. Full Moon to New Moon or new moon to full moon occur in span of 15 days. It’s also a fact that a Solar or Lunar Eclipse occur on New Moon day or Full Moon day. In other words whenever Sun Moon Earth are aligned in a line. If on that day if its New Moon day a Solar Eclipse will occur. During such alignment if its Full Moon day a Lunar Eclipse will occur.
Importantly often Solar Eclipse is followed Lunar Eclipse or sometimes Lunar Eclipse precedes the Solar Eclipse in a Year. The occurrence of two eclipses in a month is not uncommon. However social media few videos are terming the Solar Eclipse on 25 Oct followed by Lunar Eclipse on 8 Nov as rare leading to serious repercussions. People should be alert against such false claims misusing scientific data.
