"A huge Bolide Meteor Explodes over La Palma, Argentina''

Fireball explodes over La Pampa, Argentina, releasing 0.38 kilotons of energy

A fireball with an impact energy of 0.38 kilotons (380 tons of TNT equivalent) was detected at 22:26 UTC on September 13, 2025, at an altitude of 22.8 km (14.2 miles) over central Argentina.

A fireball with an impact energy of 0.38 kilotons (380 tons of TNT equivalent) was detected at 22:26 UTC on September 13, 2025, at an altitude of 22.8 km (14.2 miles) over central Argentina. The event was observed from multiple provinces and produced a persistent trail and visible fragmentation.

A bright fireball was detected at 19:26 local time (22:26 UTC) on September 13, over central Argentina.

The object entered the atmosphere near latitude 38.0°S and longitude 64.8°W, at an altitude of 22.8 km (14.2 miles), releasing an estimated 0.38 kilotons (380 tons of TNT equivalent) of energy, according to NASA’s Center for Near Earth Object Studies (CNEOS).

The International Meteor Organization (IMO) received two reports submitted from observers in Bahía Blanca, Buenos Aires Province, and Puerto Madryn, Chubut Province.

Observers described the fireball as exceptionally bright, with magnitudes between −5 and −6. One report noted a white terminal flash with fragmentation and a persistent incandescent trail lasting about 90 seconds. Another described a large explosion-like flash and a red cloud that remained visible for several minutes.

This event comes just four days after another bright fireball over northeastern Brazil. On September 9, a daylight bolide was recorded at 14:49 local time (17:49 UTC) over the Atlantic Ocean, off the coast of Ceará State. According to NASA CNEOS, that object released 0.44 kilotons of energy at an altitude of 24 km (15 miles).

The American Meteor Society (AMS) and IMO received 10 reports from witnesses across Ceará, who described colors ranging from orange to blue, persistent trails, fragmentation, and sounds varying from faint hissing to thunder-like booms. Satellite imagery confirmed the atmospheric flash.

Fireballs of this scale occur several times each year worldwide. With an energy release under 1 kiloton, they typically disintegrate at high altitudes and pose no hazard to the surface.

It seems the Chinese are ready for incoming meteors, do they read the sessions ??

In the CNEOS list, after two rather quiet months, the system back from holidays could catch four within five days...!?


For one of the recent, and the one in August, there are videos:

Probably not. Too busy thinking up propaganda? Bless their communist hearts.

Follow-up on this:

Maybe it hit an aircraft that simply 'got in the way'? (That's why they denied it happened).

It could be reentry space debris, of Chinese or foreign origin, being shot down, or met halfway to reduce the risk of large size objects hitting the ground and creating damage.

They discover of comets is more often, isn't it?

From TG Solar Astronomy Laboratory of the Space Research Institute of the Russian Academy of Sciences

Comet C/2025 A6 (Lemmon) may become visible in binoculars within 10 days, and to the naked eye across the entire country within a month

Comet C/2025 A6 (Lemmon), first discovered on January 3, 2025, is increasing in brightness faster than predicted and should reach the 5th magnitude within 10-14 days, from which point it can be seen in binoculars in the night sky across the entire country. The comet is currently about 200 million kilometers from Earth, but this distance is rapidly decreasing by approximately 5 million kilometers each day. In 10 days, on October 3, the celestial body will be at 150 million km, and on October 21 it will pass at a minimum distance from Earth of less than 90 million km.

The peak brightness of the comet is forecasted to occur in late October to early November, when it is expected to reach a magnitude of 2-4 and become visible without optical instruments.

At present, the comet is rapidly moving across the sky by several degrees per day toward the constellation Ursa Major, visible throughout the country, and will pass near it in mid-October, when, as noted, it can be found with the simplest optical instruments. In the last days of October, at peak brightness, it will move into the constellations Serpens and Ophiuchus, where it should be visible to the naked eye after sunset.

We will provide updates on observation conditions.

Currently, the object has an 8th magnitude and is accessible for observation with amateur telescopes. We thank our friend, Novosibirsk photographer Alexey Polyakov, who provided his own photo of this comet taken a few days ago for this publication.

Isn't it way too slow for a meteor?

 

[Deneb]

Meteor entry speeds vary greatly, but typically fall within a range of approximately Mach 40 and Mach 300
No chance for any weapon to shoot it down
