'Unprecedented': Shockwave & 'huge roar' reported in Gran Canaria was meteorite

meteorite gran canaria
First, it ripped the sky over La Palma, La Gomera and Tenerife at great speed, like lightning that emitted colours with shades of green and red, to then cause such a roar over Gran Canaria that it was heard from many areas of the island before, finally, crashing in the sea, causing astonishment among the islanders who, at first, didn't know what it was.

Scientists have confirmed that it was a meteorite which, although it is not the first to fall in the Archipelago, there are no precedents for what happened yesterday, as it was accompanied by tremors. Fortunately, the Emergency Services announced that there is no record that it caused injuries or material damage.

The incident occurred yesterday (Wednesday) just after 3pm, although the exact time of the impact recorded by the measurement systems installed by Involcan and the National Geographic Institute (IGN) recorded various readings between 3:16pm and 4:35pm.

Translation:
The Canary Seismic Network, which operates INVOLCAN, has registered at 16:35 hours (Canary time) a seismic signal on the island of Gran Canaria caused by the passage of a powerful acoustic wave across the island.The preliminary analysis of seismograms shows a form compatible with an N-wave, produced by the impact on the earth's surface of a shock wave caused by an object, natural or artificial, moving in the atmosphere at its speed personality.The following figure shows the seismogram recorded by the GART seismic station (Artenara).The N-wave is a signal that produces a crash wave that impacts the Earth's surface and most likely its source was a solid https://es.wikipedia.org/wiki/B%C3%B3lido

New research reveals space debris, invisible meteors and near-Earth asteroids

In a new thesis from the Swedish Institute of Space Physics and Umeå University, unique methods for the analysis of radar data and simulations of meteoroids in the solar system are presented. The methods have been applied to confirm the existence of rare high-altitude meteors as well as to measure space debris from the Kosmos-1408 satellite. On November 25, Daniel Kastinen defends his doctoral thesis.

Daniel Kastinen's thesis presents results that pave the way for future research and cross-disciplinary studies on meteors as well as on space debris and near-Earth asteroids.
"My primary goal has been to carefully analyze radar measurements of meteors and space debris and evaluate the precision of the measurements. This is to improve further analysis and use the results together with the new dynamical simulations. The work paves the way for future research and allows cross-disciplinary studies on meteors as well as on space debris and near-Earth asteroids", says Daniel Kastinen.

Every day, 10-200 tons of material from space, consisting of dust- sized particles and larger pieces of material - meteoroids, fall into the Earth's atmosphere. These particles come from parent bodies such as comets and asteroids and thus date back to the time when the solar system was formed. When a meteoroid hits the Earth's atmosphere and burns up in the form of a meteor, the material is dispersed in the atmosphere. Most of these meteors are invisible to the eye but can be detected by radar.

Asteroid hit Canada on November 19, mere hours after discovery

Asteroid hit Canada hours after discovery

Astronomers spotted an asteroid just hours before it impacted with Earth this morning (November 19, 2022), near Lake Erie. This is not the first time this year astronomers have discovered a rock from space just hours before it hit Earth. But this time, it impacted over a populated area, crossing the skies of Toronto, Canada. So we have video and witnesses who said they saw, heard and felt the impact.
