Stunning video of meteor fireball somewhere over (apparently) California on night of 28/29th July. Seems to be no MSM coverage at present.
RT as it already.
WATCH: Fireball lights up night sky during DOUBLE meteor shower, green light triggers inevitable UFO speculation
A fireball lit up the night skies across Colorado and New Mexico on Tuesday night, video of which has dazzled many online, while others couldn’t help but speculate about invading aliens as a fitting addition to the chaos in 2020.

Football field-sized asteroid inbound today, with another 180-footer to follow this weekend, NASA warns
I just had the image of such an asteroid becoming a paleolithic hunters spear smashing into Earth. EM-spear with EM-effects causing volcanic eruptions, where it hits.

A mix of new items coming out, with revealing findings. 
Both falls were captured by The Desert Fireball Network (DFN) team which uses cameras across Australia to observe shooting stars and predict where meteorites land.
The team, who usually search from March to October, was postponed due to COVID-19, but as restrictions lifted it observed another meteorite fall just south of the Eyre Highway near Madura.
Astronomer Dr Hadrien Devillepoix and planetary geologist Dr Anthony Lagain originally went on a reconnaissance mission to assess the latest fall site near Madura, taking drone imagery of the area.
“Most meteorites contain a lot of metallic iron, a lot more than normal Earth rocks. This is why meteorites typically attract a magnet, or make a nearby compass ‘go crazy’,” Dr Devillepoix said.
“However the meteorite that we found almost entirely fails the compass test – the compass needle barely gets disturbed, which is really intriguing. The next step for us is to now figure out why this is happening and what is making this meteorite so different to the others we know about.”
Dr Devillepoix explained that not only do the fireball cameras allow the team to calculate where the meteorites land, they also allow it to backtrack where they came from and what orbit they were on before they hit Earth.
“We were able to determine that this meteorite was on an Aten orbit, which means that before it fell to Earth, the meteorite spent most of its time in the innermost Solar System, between Venus and Earth,” Dr Devillepoix said.
“This type of orbit is unusual because, as most meteorites come from the asteroid belt between Mars and Jupiter, they usually retain an orbital connection to this area of space.”
Two weeks later, Dr Martin Towner, operations chief of the team, led the six people team to search the site of the November 2019 fall. This fall was North-West of Forrest airport in the middle of the Nullarbor.
After just four hours of searching, they found the 300 gram meteorite that the DFN had seen come in on the night of November 18th, 2019.
This one came from a radically different orbit, pointing to the middle part of the main asteroid belt. The team is now working to uncover what secrets the two rocks hold.
John Curtin Distinguished Professor Phil Bland, the Director of the Space Science and Technology Centre, explained his team is able to learn more about meteorites on Earth by analysing data collected from strategically placed camera observatories, known as the Desert Fireball Network (DFN).
(2011 ES4) Classification: Apollo [NEO]
After returning to Earth in December 2020, Hayabusa2 will separate the capsule and return to deep space. As about half of the fuel (xenon) for the ion engine is expected to remain at this time, there is the potential to continue on to a new mission. We therefore examined what kind of mission would be possible.
Initially, a search was performed to identify celestial objects that could be reached using the residual fuel. 354 candidates were found. Then the engineering viewpoint was considered, including details such as the level of orbit control required to reach the celestial object, how well the orbit of target object was determined and the feasibility of the spacecraft operations. The size of the target object, rotation speed and type were also scrutinized to rank the celestial objects by their scientific interest. Finally, the selection was narrowed down to two objects: 2001 AV43 and 1998 KY26 (Figure 1).
Figure 1: Characteristics of the exploration candidate celestial bodies (image credit: Auburn University, JAXA).
Both these candidates are very small celestial bodies with diameters of a few tens of meters. The asteroids are referred to as ‘fast rotators’ because of their extremely rapid rotation period of just 10 minutes. An object with these characteristics has never been visited by humanity before, and the comparative observations with asteroid Ryugu are expected to deepen the scientific knowledge obtained from Ryugu.
The orbits of these two celestial objects are different, and the plan to reach 2001 AV43 goes via Venus, while the route to 1998 KY26 is via another asteroid. We call these scenarios EVEEA (Earth → Venus → Earth → Earth → Asteroid) and EAEEA (Earth → Asteroid → Earth → Earth → Asteroid). The main difference is the Venus swing-by in 2024 for the EVEEA scenario and the asteroid fly-by in 2026 for EAEEA (Figure 2). The arrival at 2001 AV43 is scheduled for November 2029, and the arrival at 1998 KY26 is scheduled for July 2031. They will be long-term missions that will take about 10 years.

We plan to focus on one of the two candidate missions this fall. This mission and the budget must be approved in order to actually proceed with the extended mission. After safely delivering the capsule to Earth, we look forward to moving onwards to new challenges!

- Advance long-term navigation technology within the Solar System.
Based on the engineering achievements of the Earth-return mission, the extended mission will advance the development of operation technology necessary for more flexible and distant exploration, and for scientific observations during long-term navigation and fly-bys. - Realization of fast rotating asteroid exploration.
The extended mission will investigate rapidly rotating small asteroids –an unexplored area—and further deepen the scientific knowledge obtained from Ryugu. In addition, the mission will aim to acquire new asteroid exploration technology by the approach within this special environment, where the rotation speed is sufficiently fast that the centrifugal force dominates gravity on the asteroid surface. - Acquisition of science and technology that contributes to Planetary Defense.
Asteroids 10s m in size can cause regional damage if they collide with the Earth. Through exploration of this asteroid type and elucidation of their origin, technology and knowledge can be acquired that contributes to activities to prevent disasters caused by celestial objects colliding with the Earth (Planetary Defense).
We plan to focus on one of the two candidate missions this fall. This mission and the budget must be approved in order to actually proceed with the extended mission. After safely delivering the capsule to Earth, we look forward to moving onwards to new challenges!

WATCH: Indonesian countryside plunged into darkness as volcano unleashes towering column of ash — RT World News
Behaving like a capacitor [?] a highly charged comet / asteroid conducting current from the Solar system and zipping by Earth could have a serious discharge effect - enhanced by its own EM-field - [?] maybe like (I'm getting the mental image of) an electromagnetic whip smashing into the EM-field and mantle of our planet.
Causing volcanoes activating, in areas where ever this energy-whip hits.
When this "EM-whip" hits Earth the strike could ripple through the planet [?] and Earth could behave as a drum / fluid filled balloon, so these ripple-waves might travel through the mantle and cause volcano eruptions on different geographical locations.

NASA warns of upcoming close shave with asteroid as doomsday preacher predicts ‘apocalyptic fireball’
Two asteroids are set to dart past Earth in the coming days, while NASA has warned about an impending close shave with an airplane-sized space rock. A doomsday preacher has also issued a dire warning about the upcoming encounter.
Two asteroids are set to dart past Earth in the coming days, while NASA has warned about an impending close shave with an airplane-sized space rock. A doomsday preacher has also issued a dire warning about the upcoming encounter.
Greatly enhanced detection techniques have allowed astronomers to witness an ever-increasing number of asteroid flybys in recent years. The latest installment will see two space rocks skim past Earth this week. Both of the rocks were only spotted in recent days, a reminder of the threat that undetected asteroids potentially pose to our planet.
Thankfully, both of the rocks will pass at a safe distance of more than 1.5 million kilometers (932,056 miles). However, on September 1 we’re set for a far closer encounter, when a 28-meter space rock, officially known as 2011 ES4, will skim past Earth at only one third of the distance between our planet and the moon.
The visitor will whizz by at a speed of nearly 30,000 kilometers (18,600 miles) per hour. NASA has labelled it a "Potentially Hazardous Asteroid" because of possible risk it poses to our Earth.
While 2011 ES4 will almost certainly fly past our planet at a safe distance, Pastor Paul Begley has issued dire warnings about it heralding the end of the world.
“It's been confirmed, incoming fireballs, apocalyptic, headed in our direction,” the self-proclaimed End Times prophesier forecast in a recent video on his popular YouTube account.
Begley cites biblical passages mixed with cherry-picked scientific evidence as “proof” that the planet is in mortal danger from incoming “apocalyptic fireballs”.
“I've been talking about this for a decade because we knew, according to the Bible, we knew it was coming - even without scientific proof,” he explained. “Even Stephen Hawking says the Earth will be consumed in fire in 2600. I think it's gonna be way way sooner than that because the Bible says it in second Peter, chapter three.”
Begley claimed that “more than 100 tonnes of space dust and rock” will rain down into our atmosphere every day in a sign of the impending apocalypse. Unsurprisingly, there is no scientific basis for these claims.

Looks like Arecibo is out of action again, a suspicious man could wonder if there might be more to it?

A Broken Cable Has Smashed a Huge Hole in The Arecibo Observatory
One of the world's most prominent astronomical observatories has a hole.
www.sciencealert.com
From Spaceweather.com:
On August 7th, an unusual object flew past the sun. (Spoiler Alert: It's not an alien armada.) "It was a triple comet," says Karl Battams of the Naval Research Lab in Washington DC, who made this animation using coronagraph images from the Solar and Heliospheric Observatory (SOHO):
"The two main components are easy to spot, with the third, a very faint, diffuse fragment following alongside the leading piece," he says.
SOHO finds comets all the time. Most are Kreutz sungrazers, fragments of a giant comet that broke up more than 1000 years ago. Since the observatory was launched in 1995, SOHO has discovered more than 3000 members of the Kreutz family dive-bombing the sun.
And that's what makes this comet unusual. "It is not a member of the Kreutz family," says Battams. "Its orbit doesn't match. We're not yet sure where it came from."
Shortly after the comet cluster showed up in SOHO images, a rumor began to spread on social media: Spaceships are sling-shotting around the sun. "No," says Battams. "It's a comet. If it waddles like a duck, and quacks like a duck... chances are it's a duck! This object shows all the classic signs of being a comet: diffuse, elongated, has a tail, and follows a path that is clearly dominated by the sun's gravity."
The triple comet is now receding from the sun, fading rapidly from view. There's a slim chance that large ground-based telescopes might be able to track it. If so, they could find clues to its make-up and origin.
"Unfortunately, the prognosis for small fragmenting comets like this is not good," says Battams. "This was probably this comet's first and last pass by the sun, as it has likely now crumbled away entirely. But SOHO will continue to keep watching the sun, and waiting for our next special cometary offering to come along."
Also on the 16th of August, from SOTT:
