TOTAL LUNAR ECLIPSE
November 8, 2022

Total lunar eclipses are always spectacular to watch. On November 8, for about 85 minutes, the Moon will completely turn red.

Moonrise and Partial Eclipse
Looking at the East-northeast (ENE) horizon, the Moon will rise at 5:19 PM, several minutes after the partial eclipse begins. It will be accessible around 30 minutes after the moonrise, though the Moon's low altitude of about 6° above the ENE horizon at that time affects the visibility of the partial eclipse.

Total and Maximum Eclipse
The total eclipse will begin at 6:16 PM, as the Earth's inner shadow (or umbra) fully covers the Moon. Maximum eclipse, when the Moon is closest to the center of the Earth's shadow, will occur at 6:59 PM, when the Moon is about 22° above the ENE horizon. The Moon will remain completely red until 7:41 PM.

Partial and Penumbral Eclipse
As the Moon moves away from the Earth's inner shadow (or umbra), the partial eclipse will be visible until 8:49 PM. After that, the Moon still passes the Earth's outer shadow (or penumbra), although it will be hardly noticeable (there is no "dark bite"). Known as the penumbral eclipse, it will last until 9:56 PM.

Lunar eclipses are safe to watch – there's no need to wear protective glasses or filters for the eyes. The next total lunar eclipse visible in the Philippines is on September 8, 2025.

ASTRONOMICAL EVENTS
November 2022

November 1: Moon at First Quarter
An almost half-illuminated Moon will be observable in the sky around 5:41 PM, about 51° above the South horizon. The Moon will be accessible until around 11:15 PM, about 46 minutes before it sets at the West-southwest horizon. There will be another First Quarter Moon on November 30.

November 2: Conjunction of the Moon and Saturn
The Moon and Saturn will share the same right ascension at 5:08 AM, though it is not visible since the pair is below the horizon. The best time to observe is on November 1, when the Moon and Saturn reach the highest point in the sky at 6:34 PM (58° above the South horizon) until around 11:15 PM, about 46 minutes before the Moon sets.

November 5: Conjunction of the Moon and Jupiter
The Moon and Jupiter will share the same right ascension at 4:23 AM, though it is not visible since the pair is below the horizon. The best time to observe is on November 4, around 7:00 PM (56° above the Southeast horizon), about two hours before the Moon and Jupiter reach the highest point in the sky (73° above the South horizon) until around 2:10 AM, about 42 minutes before the Moon sets.

November 8: Total Lunar Eclipse
The Moon will turn red as the Earth's shadow covers it. The Moon will rise at 5:19 PM, several minutes after the partial eclipse begins. The Moon turns red completely (total eclipse) from 6:16 PM until 7:41 PM. The Moon is closest to the center of the Earth's shadow (maximum eclipse) at 6:59 PM. The partial eclipse ends at 8:49 PM.

November 8: Lunar occultation of Uranus
The Moon will pass in front of Uranus, hiding the latter during the total lunar eclipse. In the Philippines, this occultation is only visible in the Northern and some parts of Central Luzon, between 7:01 PM to 7:34 PM. Uranus will lie almost opposite the Sun (opposition) on November 9.

November 11: Conjunction of the Moon and Mars
The Moon and Mars will share the same right ascension at 9:46 PM (27° above the East-northeast horizon). The pair will reach the highest point in the sky at 2:11 AM (80° above the North horizon).

November 16: Moon at Last Quarter
An almost half-illuminated Moon will rise at 11:52 PM. The Moon will be observable until around 5:41 AM, about 16 minutes before sunrise.

November 17-18: Leonid meteor shower
The Leonids will peak on the night between November 17 to 18 – reduced visibility due to the closeness of the Waning Crescent Moon to the radiant. The best time to observe the meteors is during the predawn hours of November 18, when the shower can produce up to 15 meteors per hour in dark-sky sites.

November 24: New Moon
The best time to do stargazing is during a moonless night.

November 29: Appulse of the Moon and Saturn
The Moon and Saturn will make a close approach, passing within 3°56' of each other at 2:57 PM, though it is not observable because it is daytime. The best time to view the pair is around 6:30 PM (51° above the Southwest horizon) up to around 10:00 PM, about 37 minutes before Saturn sets.

According to the World Health Organization, young children are prone to lead poisoning as they ingest four to five times more lead than adults. In “The Toxic Truth: Children’s Exposure to Lead Pollution Undermines a Generation of Future Potential” (2020) by UNICEF and Pure Earth, it revealed that an estimated 20 million children in the Philippines have blood lead levels beyond the 5 ug/dL based from the Institute for Health Metrics Evaluation data.

In solidarity with this year's International Lead Poisoning Prevention Week, tune in to Ang Tinig Klima and catch our guests: Regional Director Omar Saikol from the DENR Environment Management Bureau-Region XII, Country Director Larah Ortega-Ibañez and National Consultant Dr. Lynn Crisanta Panganiban from the Pure Earth Philippines as they talk about the health effects of lead exposure especially to children, and the national and local government efforts to prevent exposure and actions to eliminate lead paints.

The show will be hosted by DENR Dir. Elenida Basug and Radyoman Jenny Pahilanga of RMN DZXL 558 Manila.

Be part of the discussion! Catch the episode on DENR Climate Change Service page, RMN DZXL 558 Manila page and radio station DZXL 558khz on Friday, October 21, 2022, from 3:00PM to 4:00PM.

Nagbabago ang panahon, panahon na para magbago!

| Aside from being a distinct faunal region, Mindoro is also home to unique flora! The mountainous island is home to one of only two native species of pine trees in the Philippines.

Merkus pine (Pinus merkusii) can only be found in the highlands of Sumatra, Indonesia and the Philippines, specifically Mindoro and Zambales. Locally called Mindoro pine, it generally occurs at moderate altitudes, mostly 400–1,500 m, growing 25 to 45 meters tall.

This native pine tree species thrives within Mounts Iglit-Baco Natural Park – home of the largest population of the critically endangered tamaraw.

[TECHNOLOGY OF THE WEEK]

A technology transfer scheme for whole corn macro-propagation of lakatan and bungulan was able to provide smallhold banana growers with an affordable alternative source of quality planting materials.

Nueva Vizcaya State University, in partnership with Balangon Integrated Growers Association of Sawmill, produced 7,473 macro-propagated plantlets. Fifty percent of which was sold to the Office of the Provincial Agriculturist, Nueva Vizcaya for distribution to farmer-beneficiaries.

Based on the profitability analysis of the project, a macro-propagated plantlet costs PhP 10.28 and sold at PhP 25, giving an income of PhP 14.72. Total production cost for a batch of 2,000 macro-propagated plantlets was PhP 20,556.66 with gross income of PhP 50,000 and net income of PhP 29,443.34.

The World Migratory Day is a global campaign that aims to raise awareness on migratory birds and the need for international cooperation to conserve them.

It is celebrated on two peak days every year (second Saturday in May and in October) to recognize the cyclical nature of bird migration and the different peak times of migration along the world’s flyways.

This year’s theme, “𝘋𝘪𝘮 𝘵𝘩𝘦 𝘓𝘪𝘨𝘩𝘵𝘴 𝘧𝘰𝘳 𝘉𝘪𝘳𝘥𝘴 𝘢𝘵 𝘕𝘪𝘨𝘩𝘵,” focuses on the impacts of light pollution on migratory birds. Most birds migrate at night and need dark skies to safely navigate between their breeding and nonbreeding grounds. This year’s celebration calls for action to reduce artificial light at night.

October is Tamaraw Month 🤗💚

October is ! We celebrate the Philippines’ largest endemic land mammal and its conservation with the theme, “Tamaraw na Tinatangi, Pamana ng Lipi” (Revered Tamaraw, Our People’s Legacy). 💚

The tamaraw is an endemic species of dwarf water buffalo found only on Mindoro island. Through the years, we have been working with the DENR-Tamaraw Conservation Program in their mission of protecting and conserving this critically-endangered species. Learn more about some of our projects with them and how you can help !

Science Trivia and Facts
Did you know?

Babies have around 100 more bones than adults.

Babies have about 300 bones at birth, with cartilage between many of them. This extra flexibility helps them pass through the birth canal and also allows for rapid growth. With age, many of the bones fuse, leaving 206 bones that make up an average adult skeleton.
