Partial Lunar Eclipse to be visible from West Africa and much of the Americas.

A partial Lunar Eclipse will occur on Friday 28 August 2026, starting at 1.25 am GMT. The whole eclipse will be visible across all of South America and the Atlantic, and most of North America, and most of West Africa and the western Maghreb, and western Iberia while part of the eclipse will be visible from parts of the northwest of North America, the remaining parts of the Maghreb and West Africa, as well as much of Central and Southern Africa, European Russia, the remainder of the Middle East, and Western and Central Europe, and parts of Norway. although in these areas the Moon will either rise part way through the eclipse, or set before it is complete.

The Moon produces no light of its own, but 'shines' with reflected light from the Sun. Thus, at Full Moon the Moon is on the opposite side of the Earth to the Sun, and its illuminated side is turned towards us, but at New Moon the Moon is between the Earth and the Sun, so that its illuminated side is turned away from us.

Lunar eclipses occur when the Moon passes through the Earth's shadow. This can only happen at Full Moon (unlike Solar Eclipses, which happen only when the Moon passes between the Earth and the Sum, and therefore only occur at New Moon), but does not happen every Lunar Month as the Sun, Moon and Earth are not in a perfect, unwavering line, but rather both the Earth and the Moon wobble slightly as they orbit their parent bodies, rising above and sinking bellow the plane of the ecliptic (the plane upon which they would all be in line every month).

How the differing inclinations of the Earth and Moon's orbits prevent us having an eclipse every 28 days. Starry Skies.

Because the Moon is passing through a shadow, rather than being blocked from our view, it does not completely disappear during an eclipse like the Sun, but in a total Lunar Eclipse goes through two distinct phases of dimming, the Penumbra, when it is still partially illuminated by the Sun, and the Umbra, when the Earth completely blocks direct sunlight from the Moon. This does not result in complete darkness, as the Moon is still partially lit by reflected Earthlight, but it does turn a deep, dark red colour.  In a partial eclipse the Earth passes completely through the Moon's penumbra, but only partly through its umbra.

Thirty confirmed deaths following landslide at landfill site in Guinea.

Thirty people have been confirmed dead, with another 22 people injured, six of them seriously, following a landslide at a landfill site in the Gbessia Commune ‌of Conakry, the capital of Guinea, on Sunday 23 August 2026. The incident happened at about 2.00 am local time, and caused piled waste from the city to collapse onto nearby dwellings, destroying a number of homes. Landslides are a common problem after severe weather events, as excess pore water pressure can overcome cohesion in soil and sediments, and even artificial deposits such as those found at landfill sites, allowing them to flow like liquids. Approximately 90% of all landslides are caused by heavy rainfall.

Authorities in Conakry were reportedly aware of the dangerous situation at the waste site, and had begun to move people from homes close to the site, ahead of a planned closure from Sunday 30 August, which was to be followed by the moving of much of the accumulated waste to a site outside of the city. This move has now been brought forward, with people being more people being moved out of their homes, and waste being loaded onto trucks as it is searched for survivors or Human remains.

West Africa has a distinct two season climatic cycle, with a cool dry season during the northern winter when prevalent winds blow from the Sahara to the northeast, and a warm rainy season during the northern summer when prevalent winds blow from the Atlantic Ocean to the southwest. These warm winds from the Atlantic are laden with moisture, which can be lost rapidly when the air encounters cooler conditions, such as when it is pushed up to higher altitudes by the mountains of the Fouta Djallon in Guinea.

Stephanorhinus kirchbergensis: A Rhinoceros from the Pleistocene of Romania.

Three species of Rhinoceros are known from the Middle-to-Late Pleistocene of Romania, the Woolly Rhinoceros, Coelodonta antiquitatis, a cold-adapted species associated with the various glacial phases, the Narrow-nosed rhinoceros, or Steppe Rhinoceros, Stephanorhinus hemitoechus, a species associated with the warmer, interglacial phases, and Merck's Rhinoceros, Stephanorhinus kirchbergensis, a larger species which may have reached as much as three tonnes, making it larger than the White Rhinoceros, Ceratotherium simum, the largest extant Rhinoceros species. Merck's Rhinoceros also appears to have favoured warmer phases, and possibly to have been restricted to the Eemian Interglacial (between 130 000 and 150 000 years ago), although specimens have been found from Siberia which apparently lived alongside Woolly Rhinoceroses, suggesting the species may have been longer lived more tolerant of climatic variation than it is generally given credit for.

In a paper published in the North-Western Journal of Zoology on 15 June 2026, Vlad Codrea of the Paleotheriology and Quaternary Geology Laboratory at Babeș-Bolyai University, the Department of Natural Sciences at Mureș County Museum, the Department of Natural History at Țării Crișurilor Museum, and the Emil Racoviță Speleological Institute, and Aurelian Popescu of the Department of Natural Sciences at the Museum of Oltenia Craiova, describe a partial Rhinoceros mandible from Dolj County in southwestern Romania. 

The mandible was discovered by English engineer William Heerlein Lindley, who was working on a water supply system for the city of Craiova, which had undergone a period of rapid expansion during the late nineteenth century, leaving the system of wells which had traditionally provided water for its residents wholly inadequate. It is unclear exactly where Lindley found the mandible, but it probably came from the Upper Terrace of the Jui River Basin, which reaches its greatest width to the east of Craiova, and where Lindley carried out considerable work, channelling water from natural springs into a system of cast-iron pipes to supply the city. The Upper Terrace has also yielded Woolly Mammoth, Mammuthus primigenius, Woolly Rhinoceros, Coelodonta antiquitatis, and Irish Elk, Megaloceros giganteus, fossils, and is considered to be Late Pleistocene in age.

Lindley gave the mandible to Alexandru and Aristia Aman, who had a collection of art, antiquities, and books, which in turn was passed to the Olteniei Museum in Craiova in the 1950s, with the specimen becoming part of that museum's natural history collection.

The specimen is the rear part of the mandible of a large Perissodactyl, with the anterior portion broken off, a broken area on the anterior edge of the coronoid process. This broken area makes it hard to judge the  elevation of the anterior edge of the vertical branch of the mandible. The teeth have also been broken from the jaw, but this is recent damage, probably caused during its excavation.

The damage to the jaw removes many of the diagnostic features used when classifying Perissodactyls, though its large size rules out anything but a large Rhinoceros, while still being too small for the truly enormous Elasmotherium. It also has a nutrient foramina on the ventral side of the symphysis, a feature associated with Merck's Rhinoceros, leading Codrea and Popescu to conclude that it should be assigned to this species.

While the teeth of the specimen are missing, they were clearly all fully erupted, indicating that it was an adult at time of death. It was probably of about average size for a specimen of Stephanorhinus kirchbergensis. The exact age of the specimen is impossible to know, given the circumstances of its discovery. If it does come from the sediments Lindley excavated at Malu Mare when laying his pipeline, then it would be the oldest known Rhinoceros from Romania, as well as having come from deposits which also yielded cold-adapted species such as Woolly Rhinoceros, Woolly Mammoth, and Irish Elk, although it is possible that Lindley discovered it elsewhere, so this cannot be asserted with any confidence.

The Kappa Cygnid Meteor Shower.

The Kappa Cygnid Meteor Shower is visible some years between the months of June and September, peaking between 3 and 25 August, with the best peak rate generally falling before dawn on 18 August, when the shower can produce 2-3 meteors per hour, with these tending to be bright fireballs with multiple fares. The meteor shower gains its name from the star Kappa Cygnus, which it is close to at the peak of its activity, and which is circumpolar in the Northern Hemisphere (i.e., close to the North Pole, and permanently above the horizon), although generally invisible in the Southern Hemisphere. If the shower does appear, viewing should be reasonably good, as activity will peak two days before the first quarter Moon, which will be in the constellation of Virgo, providing minimal light interference. However, the meteor shower is notoriously erratic, not being seen every year; it was last seen in the Augusts of 2020 and 2021, and before that in 2013 and 2014, then before that in 2007.

Meteor showers are thought to be largely composed of material from the tails of comets. Comets are composed largely of ice (mostly water and carbon dioxide), and when they fall into the inner Solar System the outer layers of this boil away, forming a visible tail (which always points away from the Sun, not in the direction the comet is coming from, as our Earth-bound experience would lead us to expect). Particles of rock and dust from within the comet are freed by this melting (strictly sublimation, transforming directly from a solid to a gas due to the low pressure on it's surface) of the comet into the tail and continue to orbit in the same path as the comet, falling behind over time.

The source body of the Kappa Cygnid Meteors remains somewhat of an enigma. The low number of asteroids, and their irregular arrival, suggests they are an old shower potentially derived from an object no longer visiting the Inner Solar System, whereas the brightness of the meteors suggests a younger origin. One possible solution to this is that they are derived from a body whose orbit undergoes a sinusoidal oscillation, something which can be caused if a body is forced into an orbital resonance with a larger body, often Jupiter in our Solar System. 

How the passage of the Earth through a meteor shower creates a radiant point from which they can be observed. In The Sky.

One potential parent body for the Kappa Cygnid Meteors which has been suggested is 2008 ED69, an asteroid which has an orbit with a 2:1 resonance with that of Jupiter and an orbital period of 4.96 years, which is thought to have been pushed into and out of Earth-crossing orbits repeatedly over the past 6000 years. However, more recent studies have established that the Kappa Cygnid Meteor Shower has an orbital period of 7.12 years and is locked into a 5:3 orbital resonance with Jupiter, ruling out 2008 ED69 as a potential parent body.

At least 53 dead following Magnitude 7.7 Earthquake off the coast of Flores Island, Indonesia.

The Indonesian Meteorological, Climatological, and Geophysical Agency recorded a Magnitude 7.7 Earthquake at a depth of about 15 km, to the north of the Island of Flores in East Nusa Tenggara Province, Indonesia slightly before 5.00 am on Saturday 15 August 2026, Eastern Indonesian Time (slightly before 10.00 pm on Friday 14 August, GMT). The Earthquake was felt as far away as Bali, and caused a tsunami as high as 1.6 m on some parts of the coast of Flores. The initial event has been followed by more than three hundred aftershocks.

At least 53 people have died as a result of this event, the majority of them killed in their sleep as buildings collapsed onto them, making this the most deadly Earthquake to hit Indonesia since 2022. A further 135 people are known to have been injured, with more than 5000 people displaced and over 1900 homes damaged or destroyed. The Earthquake also caused damage to at least 93 educational facilities, 36 health facilities, 38 government offices, and five places of worship. A maritime passenger terminal collapsed in Maumere on the north coast of Flores.

Flores is one of the Lesser Sunda Islands, which are located on the northern part of the Timor Microplate. This is trapped between the converging Eurasian and Australian Plates, both of which are being subducted beneath it. In the south the Australian Plate is passing under the island of Timor, while in the north the Eurasian Plate is being subducted in the same way. This is not a smooth process; the rocks of the various plates constantly stick together, only to break apart again as the pressure builds up, causing Earthquakes in the process.

The subduction zones beneath the Timor Microplate. Hamson (2004).

Earthquakes along subductive margins are particularly prone to causing tsunamis, since these often occur when the overlying plate has stuck to the underlying plate, being pulled out of shape by its movement. Eventually the pressure builds up too far and the overlying plate snaps back, causing an Earthquake and a tsunami.
