The event was recorded in the framework of the SMART project, operated by the Southwestern Europe Meteor Network (SWEMN), from the meteor-observing stations located at the astronomical observatories of Calar Alto (Almería), Sierra Nevada (Granada), and Sevilla. The event has been analyzed by the principal investigator of the SMART project: Dr. Jose M. Madiedo, from the Institute of Astrophysics of Andalusia (IAA-CSIC).
Across Henan, rains deluged 1,700 large-scale farms, killing more than a million animals, and whose many small farmers still play a major role in meat production. The floods also caused a major explosion in an aluminum alloy unit in central Henan.
At least 14 people lost their lives in Zhengzhou city when their subway train flooded. More than 500 people were trapped in the subway in one of the worst-affected areas of the city.
China's biggest river, the Yangtze, and several of its tributaries have risen to dangerous levels after days of heavy rain, forcing evacuations of thousands of people and triggering an unprecedented emergency response alert.
A very serious double earthen dam failure sent 46 million cubic meters of water to the Hulunbuir area of Inner Mongolia, causing massive flooding.
The Three Gorges Dam has successfully contained the heavy floods, sighing relief to Chinese authorities, as a collapse could have had an even more catastrophic impact on the area.
Severe flooding caused by historic rainfall wreaked havoc across western Europe taking the lives of 189 people. Tens of thousands were unable to return to their homes and were left without access to power and drinking water. Towns in river valleys and low-lying plains in Germany, the Netherlands, Belgium, France, and Austria were heavily damaged. Most of the affected areas had not experienced that much rainfall in 100 years.
Drought and extreme heat triggered the two largest wildfires in the Western US. The fires have burned land nearly the size of New York City, Los Angeles, and Chicago combined.
The Dixie Fire in California scorched 241,000 acres has destroyed more than 60 houses. The widespread fires have forced the evacuation of more than 7,800 residents.
The Bootleg Fire is still raging in southern Oregon, burning 413,000 acres since igniting this month. The fire has torn through more than 400 houses.
Greek firefighters faced dangerous and unprecedented conditions as they battled 154 wildfires through Athens, with one of them threatening Mount Parnitha national park — one of the last remaining substantial forests near the city. Meanwhile, in Turkey, eight people died in the country's worst blaze in decades that raged through swaths of the southern coast.
Hot weather and strong winds fueled multiple wildlife fires in Akkar, Lebanon, consuming the iconic Lebanese pine forests. The flames forced thousands to evacuate.
And on the southern hemisphere, Brazil, Argentina, and Uruguay reported rare snowstorms and surprisingly cold temperatures this winter.
A magnitude-8.2 earthquake rattled Chignik, Alaska this month, it has been recorded as the most powerful U.S. earthquake in half a century. Several Alaskan coastal communities were evacuated following the quake, but no major damage was reported due to the remote location and depth of the epicenter.
Have you noticed that more and more people, cattle, buildings, and trees are getting struck by lightning? Things are charging up in higher layers of the atmosphere. Keep your eyes open, and prepare accordingly!

A meteorite with a "flash of light" soars through the skies of Santiago as far away as in Tomé and the Biobío region , several Internet users report through social networks.
The cameras manage to capture the meteorite with a strong light illuminating the sky of various sectors of the capital of Chile.
We have compiled some videos of the meteorite fall in Santiago, Chile:
Stacking of 15 unfiltered exposures, 240 seconds each, obtained remotely on 2021, July 30.3 from X02 (Telescope Live, Chile) through a 0.61-m f/6.5 astrograph + CCD, shows that this object is a comet with a compact coma about 8" arcsecond in diameter (Observers E. Guido, M. Rocchetto, E. Bryssinck, M. Fulle, G. Milani, C. Nassef, G. Savini, A. Valvasori).

It occurred around 11:15 p.m., according to the American Meteor Society (AMS).
The AMS received 85 reports about the bright meteor spotted over Connecticut, Massachusetts, Maine, New Hampshire, Rhode Island and Vermont. It was also seen in New Jersey and New York, as well as Canada.
The event dazzled people across the region, with Sarah C., from Cumberland, Maine, saying it left her speechless.
"Never seen anything like it," she reported to the AMS. "Reminded me of a shooting star but much faster and much brighter."
They're red, they're reasonably big, and they have no business being in the main asteroid belt, but their discovery confirms the complex conditions in place when the solar system was still forming.
New research published in the The Astrophysical Journal Letters details the discovery of two extremely red main-belt asteroids. Named 203 Pompeja and 269 Justitia, the asteroids have a redder spectral signature than any other asteroid in the main belt, that highly populated band of asteroids situated between the orbits of Mars and Jupiter. The new paper was led by Japan Aerospace Exploration Agency (JAXA) astronomer Sunao Hasegawa.
Importantly, these red asteroids resemble trans-Neptunian objects, that is, objects located farther away than Neptune, the most distant planet from the Sun (with no disrespect to dwarf planet Pluto). This could mean that 203 Pompeja and 269 Justitia formed way out there in the Kuiper Belt and then drifted inward when the solar system was still young. If confirmed, the new finding shows how chaotic the conditions were back then and that materials from different parts of the solar system would sometimes mix together.
The purpose of the study was to document the distribution and composition of large asteroids in the main belt. Large asteroids, especially those larger than 60 miles (100 km) in width, are likely survivors of the solar system's early days. By studying these objects, the scientists were hoping to catch a glimpse of what the conditions were like some 4 billion years ago.












Comment: A few days ago another meteor fireball streaked across the sky over New England.
