Fireball 4

Meteor fireball over the coast of Santa Catarina, Brazil


The meteor occurred over the coast of Santa Catarina around 2:05 am this Wednesday (28/07). The journey lasted just under 3 seconds and the glare was quite intense. The record was made by the meteor monitoring station in Monte Castelo-SC. Other cameras from the BRAMON network also recorded the event. Did you see something like that?

Meteor fireball lights up the sky over Pilbara, Western Australia

Perth Observatory’s Matt Woods confirmed it was a meteor known as a bolide — French for missile. Appearing as a fireball in the sky, it was likely a space rock the size of a cricket ball or slightly larger plunging towards earth that burned up high in Earth’s atmosphere, before it could hit.
Two of Roebourne's finest have been left gobsmacked after their night on the beat was interrupted by a meteor.

Police bodycam vision captured the fireball lighting up the Pilbara sky, shocking the officers who were talking with a local at the time.

"Did you see that, did you see that?" says one.

"Oh wow! That was a big flash I thought that was a torch. Make a wish, quick, make a wish," says a female officer who has her back turned when the meteor first lights up the sky.

North Texas residents took to social media Sunday night to discuss and share videos of a flash streaking across the sky.

Many people across Dallas-Fort Worth noted they saw a brilliant fireball about 8:57 p.m. Sunday. In fact, it was seen as far south as Austin, as far north as Oklahoma and as far east as Louisiana.

It streaked from the southwest to the northeast and exploded, evidently over Northeast Texas. One resident in Bonham said it "shook his house."

Meteor fireball over the south of Spain (July 24)

On 24 July 2021, at about 0:00 h local time, a slow-moving fireball was spotted over Spain. This bolide was generated by a rock from an asteroid that hit the atmosphere at about 75,000 km/h. The fireball overflew the provinces of Ciudad Real (region of Castilla-La Mancha) and Jaén (Andalusia). It began over the south of Ciudad Real at an altitude of about 85 km, and ended over the province of Jaén at a height of around 34 km.

This bright meteor was recorded in the framework of the SMART project, operated by the Southwestern Europe Meteor Network (SWEMN), from the meteor-observing stations located at Sevilla, La Hita (Toledo), La Sagra (Granada), Calar Alto (Almería), Cerro Negro (Sevilla), Sierra Nevada (Granada), and Madrid (Jaime Izquierdo, Complutense University of Madrid). 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).

Comet 2

New Comet C/2021 N3 (PANSTARRS)

CBET 5003 & MPEC 2021-O39, issued on 2021, July 22, announce the discovery of a new comet (magnitude ~20.5) on CCD images taken on July 13.5 UT with the Pan-STARRS1 1.8-m Ritchey-Chretien reflector at Haleakala (numerous pre-discovery observations going back an additional month were later identified). The new comet has been designated C/2021 N3 (PANSTARRS).

Stacking of 16 unfiltered exposures, 180 seconds each, obtained remotely on 2021, July 14.3 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 9" arcsecond in diameter elongated toward PA 230 (Observers E. Guido, M. Rocchetto, E. Bryssinck, M. Fulle, G. Milani, C. Nassef, G. Savini, A. Valvasori).

Comet 2

New Comet P/2021 N2 (Fuls)

CBET 5000 & MPEC 2021-N137, issued on 2021, July 15, announce the discovery of a new comet (magnitude ~18.3) on CCD images taken on July 09.4 UT with the Catalina Sky Survey's 0.68-m Schmidt reflector (pre-discovery Catalina observations from June 27 were identified later). The new comet has been designated P/2021 N2 (Fuls).

Stacking of 28 unfiltered exposures, 60 seconds each, obtained remotely on 2021, July 10.1 from Z08 (Telescope Live, Oria) through a 0.7 m f/8 Ritchey Chretien + CCD, shows that this object is a comet with a compact coma about 8" arcsec in diameter and a tail 10" long in PA 250 (Observers E. Guido, M. Rocchetto, E. Bryssinck, M. Fulle, G. Milani, C. Nassef, G. Savini, A. Valvasori).

Chicxulub impact event left evidence of giant ripples under Louisiana

When the Chicxulub impact blasted into the Yucatan Peninsula, it generated massive tsunamis that left their signature thousands of miles away.

Over 800 miles from the impact site, massive ripples buried deep underground record the devastation wrought by an asteroid. The Chicxulub impact, the likely smoking gun for the extinction of the dinosaurs at the end of the Cretaceous, sent tsunamis tearing across the Gulf of Mexico. These giant waves left ripples in the undersea sediments as they passed and a new study has found what might be the largest "megaripples" on the planet.

The darkest dayLet's step back a moment. It has been around 40 years since the Chicxulub impact, located on the northern shores of the Yucatan Peninsula, was identified as the potential cause of the famed Cretaceous-Tertiary extinction (a.k.a., the K-t boundary). Since then, signs of this massive collision have been found across the planet. These include a layer of iridium from the asteroid, droplets of molten rock that rained down after the impact, wave deposits as far away as North Dakota and the charred remains of forest burned by the heat of the blast.

Large meteor fireball visible for 27 seconds over Puerto Rico

A large meteor was visible at 4.55 local time this Friday from almost all of Puerto Rico as reported by the Caribbean Astronomy Society (SAC).

"Although most meteors are only visible for a few seconds, this event was significant since images that we managed to capture show that it was visible for 27 seconds, that is almost half a minute," said Eddie Irizarry, vice president of the SAC.

"It looked bigger and bigger, it didn't look like a common meteor," said Idaly Correa, who witnessed the spectacular sighting from the municipality of Guayanilla.

The SAC director clarified that despite the long duration of the meteor, it was not space debris, but a natural meteor, that is, a space rock disintegrating through the atmosphere.
