Burning object recorded in New Zealand sky likely a meteor

Queenstown resident Matt Wilcox was lucky enough to witness what was probably a meteor on Wednesday evening.
A Queenstown man has captured some mysterious footage above the Remarkables mountain range.

Matt Wilcox was out for a walk when he spotted something odd.

"[It] was probably only visible for around a minute or so. Then it went behind the Remarkables and out of sight."

Southland Astronomical Society astronomer Mike Bailey had examined the footage and said he believed it was not a plane as it was moving too fast.

"It also looks dirty, aircraft contrails would normally be white," he added.

Rethinking the world's largest 'explosion': Tunguska event could have been caused by iron asteroid entering and leaving atmosphere

'At present, there are over 100 hypotheses about the nature of the Tunguska phenomenon', says Sergei Karpov. 'They include the fall of a small asteroid measuring several dozen metres consisting of typical asteroid materials, either metal or stone, as well as ice.'
For decades experts have been baffled by the shattering detonation which wiped out more than 80 million trees over a remote area of the then tsarist empire.

Explanations have focused on a meteor exploding in the atmosphere, a meteorite striking the surface, or a comet composed mainly of ice, yet apart from the wholesale destruction at ground level in an unpopulated area, there is only minuscule evidence of a space object.

In a major new contribution to the scientific debate, Dr. Sergei Karpov, leading researcher at Kirensky Physics Institute in Krasnoyarsk and his peers, argue 'that the Tunguska event was caused by an iron asteroid body, which passed through the Earth's atmosphere and continued to the near-solar orbit'.

It was 100 to 200 metres (328 to 656 feet) in diameter.

Comment: Scientists are still hanging on to the 'icy snowball' theory of comets. If one looks at comets as charged solid bodies, the effects become much more understandable

Prof. Wickramasinghe and team share potential origin and predict progression of COVID-19

Scientific researchers released their findings about the source and predicted direction of the coronavirus and proposed critical measures for the pandemic.

London, UK, — Professor Chandra Wickramasinghe and his team of researchers believe that the novel coronavirus arrived on meteorites in Oct 2019 and instantaneously infected hundreds of thousands of people through the atmosphere, as meteorites were reported in China, Northern Italy, Michigan in October 2019. This is somewhat at odds with the mainstream assertion that it originated in bats in WUHAN, China. Given this disparity, they went to great lengths to produce a timely research paper to back up their argument.

In the research paper released on COVID-19, Professor Wickramasinghe puts forward several thought-provoking arguments. Notably that: "our informed view is that many people were almost simultaneously infected and naturally inoculated with the same COVID-19 virus strain."

New Comet C/2020 H2 (Pruyne)

CBET 4761 & MPEC 2020-H220, issued on 2020, April 28, announce the discovery of a comet (magnitude ~16.5) by Theodore A. Pruyne on four 30-s CCD exposures taken with the Catalina Sky Survey's 0.68-m Schmidt telescope. The new comet has been designated C/2020 H2 (PRUYNE).

We performed follow-up measurements of this object while it was still on the PCCP webpage.

Stacking of 55 unfiltered exposures, 10 seconds each, obtained remotely on 2020, April 27.4 from X02 (Telescope Live, Chile) through a 0.6-m f/6.5 astrograph + CCD, shows that this object is a comet with a diffuse coma about 1' arcmin in diameter.

Bright meteor fireball turns night into day sky over eastern Caribbean Islands

At approximately 8:40 PM on Sunday 26th April 2020, a bright meteor streaked across the night sky, lighting up between Martinique to as north as Anguilla and as west as Puerto Rico.

A brief and bright flash of light was reported from Martinique, Guadeloupe, Saint Martin, Saint Barthelemy, Gustavia, and Puerto Rico.

Huge meteor fireball observed over Brazil

A large meteorite crossed the Brazilian night sky and became extinct at an altitude of 67 kilometers, just one kilometer above the cities of Nova Petrópolis, Canela and Gramado, in the south of the neighboring country.


Comment: 'Became extinct'?! What a strange turn of phrase, given what meteors will likely do to us some day...


This was reported this Saturday by the Heller and Jung Space Observatory, which recorded last Thursday how the bolide (a type of meteorite with a very intense brightness) fell in the Hortensias region, in a sect of the mountain ranges of the state of Rio Grande do Sul.

The best meteor during this month's Lyrid meteor shower might not have been a Lyrid at all. On April 21st, Robert Barsa was outside the city of Košice, Slovakia, watching meteors fly out of the constellation Lyra when a flash lit up the sky from a completely different direction.

"I saw it in my peripheral vision," says Barsa. "As I looked reflexively above my head, I was speechless staring at a meteor much brighter than Venus."

"The fireball was moving very slowly with at least two outbursts," he says. "It reminded me of a decaying spaceship or satellite entering the atmosphere."

A few people in the US witnessed a bright fireball created by a meteor that streaked across the sky recently. The eyewitnesses said the space rock exploded mid-air and broke apart into tiny fragments.

The American Meteor Society reported that the fireball event happened on April 20 at around 10:30 pm MDT, or April 21 at 12:30 am EDT. Although most of the eyewitness reports regarding the fireball event came from the stated of Idaho, the incident was also spotted by individuals from Washington and Oregon.

Witnessing A Fireball Event

Based on the eyewitness reports, the brightness or magnitude of the fireball varied. While some eyewitnesses stated that the fireball had a magnitude of -20 to -14, others stated that it ranged from -7 to -5. The difference in magnitude may have been caused by the sky conditions in the area where they spotted the meteor. The presence of clouds or haze in the region might have affected the brightness of the fireball.

News photographer captures video of meteor fireball streaking through Texas sky

Fireball over Beasley, TX
A KPRC 2 photographer captured video of a sight that is out of this world.

Cesar Martinez said he was driving southbound on U.S. Highway 59 early Monday morning near Beasley, Texas, when his vehicle's dashcam caught video of a bright green flash in the western sky.

Martinez said the light only lasted about six seconds before fading away.

The activity seen on camera appears consistent with video of confirmed meteor sightings. The light is the result of a space rock (meteoroid) burning up as it enters Earth's atmosphere.

While it's not clear if Monday's sighting is related, the Lyrid meteor shower reaches it's peak this week.

SCAN verified the absence of radioactivity in the meteorite that fell in El Empalme, Guayas, Ecuador.
Images of people in Ecuador manipulating a rocky body with their hands went viral on the night of Wednesday, April 22, 2020 on social media networks. In the videos, residents of the Los Naranjos compound in El Empalme (Guayas) spoke of an object that had fallen from the sky. The area also suffered several power outages.


The following morning, the Government of Ecuador confirmed that it was a meteorite according to El Comercio (Ecuador).

"The Police cordoned off the area and SCAN evidenced that the body is not radioactive, which reassures us, for the well-being of the residents," said Rodrigo Salas , assistant secretary for Nuclear Control and Applications (SCAN) of the Ministry of Energy and Non-Renewable Natural Resources of Ecuador.
