We received 15 reports about a fireball seen over Overijssel and Schleswig-Holstein on Sunday, August 22nd 2021 around 22:16 UT.

For this event, we received one video and one photo.

This pair of Hubble Space Telescope images of comet C/2019 Y4 (ATLAS), taken on April 20 and April 23, 2020, reveal the breakup of the solid nucleus of the comet. Hubble photos identify as many as 30 separate fragments. The comet was approximately 91 million miles from Earth when the images were taken. The comet has been artificially colored in this view to enhance details for analysis.
Researchers in the US have wound back the cosmic clock to determine that a spectacular comet whizzed past the Earth 5,000 years ago.

While the event isn't recorded in any historical account, the team were able to gather clues from more recently sighted comets.

In a paper published in the Astronomical Journal, they examined observations made by the Hubble Space Telescope of the comet ATLAS (C/2019 Y4), which Hubble watched break into pieces last year.

This comet is thought to be a fragment of a larger one that passed by the Earth in 1844, shining as brightly as Sirius, the brightest star in the sky.


By tracing the two comets' motions back through time, the researchers figured out that they are likely both parts of an even bigger one that last zipped through the inner Solar System 5,000 years ago, around the time that Ancient Egyptians were first settling into the Nile valley.

The meteor spotted headed from Ottawa to Montreal that was burning bright in the night sky.
Stargazers in parts of Quebec and Ontario were treated to a spectacular sight Friday night: a mysterious "fireball" shooting across the night sky.

One cottager near St. Agathe described a fluorescent green ball with a red tail, visible for roughly five seconds, with some Twitter users describing the ball as bright blue.

Marc Andrew, who is located in l'Épiphanie, told CTV he saw a ball of vivid orange and red coming from the northwest.

"I've seen shooting stars, but I haven't seen anything like this," he said, adding, "It was exactly like what you see in the movies."

Meteor fireball over Japan

fireball
On the night of the 19th, it was witnessed that something like a ball of light flowed down over a wide area such as Kanto and Kinki.

According to experts, it is a bright shooting star called a "fireball".

Late on the night of the 19th, witness information that something like a ball of light flowed down over a wide area such as Kanto and Kinki was posted on SNS one after another.

In the video sent to NHK's video posting site Scoop Box, it was confirmed that something like a shooting star suddenly brightened and disappeared at around 10:17 pm on the 19th.

Meteor was registered in SC this Thursday (19)
Brilliant and with an estimated speed of over 70 km/s. So was the meteor that had a fall recorded this Thursday (19) in Monte Castelo, in the North of Santa Catarina. The record was shared with the public this Friday (20).

According to the meteor monitoring station JJS/SC, associated with Bramon ( Brazilian Meteor Observation Network), the JJS2 camera captured the exact moment of the phenomenon. The video was posted on social networks and shows, in various ways, the luminous phase of the star.

With a magnitude of -1, the meteor lit up the sky for 4.4 seconds, peaked at a magnitude of -1. The path began to glow at azimuth 222 with an elevation of 43° and an estimated altitude of 91 kilometers. In the video, it is possible to see the moment in contrast and at different speeds, as it passed close to the Cruzeiro do Sul constellation. On the way, the meteor reached enough capacity to cover the distance between the cities of Fraiburgo and Campo Belo do Sul in Santa Catarina in less than five seconds.

Meteor fireball over Central Spain on August 18

fireball
This stunning Perseid fireball was recorded over Spain on 2021 August 18, at 2:20h local time. It was produced by a fragment (a meteoroid) from a comet. The meteoroid impacted the atmosphere at about 90.000 km/h. The fireball overflew the province of Cuenca (Region of Castilla-La Mancha). It began at a height of about 104 km and ended at an altitude of around 67 km above the ground level.

The event was recorded in the framework of the SMART project, operated by the Southwestern Europe Meteor Network (SWEMN), from the meteor-observing stations located at La Hita (Toledo), La Sagra (Granada), Sevilla, Sierra Nevada (Granada), and El Arenosillo. 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).

Unexpected Perseid meteor outburst 2021, 300% more fireballs than normal

Perseid outburst 2021

Figure 1 – 2021 Perseid rates according to CAMS Texas and CAMS California video data. The vertical scale is logarithmic. The dashed line is the level of normal annual Perseid activity.
Abstract: An unexpected outburst of Perseids was detected by low-light video observations on August 14, 2021. The outburst peaked at solar longitude 141.474 ± 0.005 degrees (equinox J2000.0) and the activity profile had a Full-Width-at-Half-Maximum of 0.08 degrees solar longitude and a peak rate of ZHR = 130 ± 20 per hour above the normal ~45 per hour annual Perseid activity. The Perseids had a steeper magnitude size distribution index than the normal annual shower component. The activity profile is similar to that derived from visual and forward meteor scatter observations. This activity may be related to the earlier smaller enhancements observed in 2018 and 2019.
Introduction

Comment: More reporting from Twitter, with one camera capturing the flashes of the outburst, but not direct footage, and all thanks to the owner's cat walking past their motion detecting camera:



It's notable that the last outburst occurred just a few years ago, and that the origin of this particular one was not expected nor, as of yet, has its origin been ascertained.

Taken together with all the other Fire In The Sky activity being documented these days, it's looking like there's been a significant increase, and that there's likely more to come: See also: Something Wicked This Way Comes

Stunning Perseid meteor fireball over Central Spain

fireball
This fireball is the brightest Perseid recorded over Spain during the activity peak of this meteor shower. The bolide, which was almost as bright as the full Moon, was observed on 2021 August 12, at 23:58h local time by numerous casual eyewitnesses. It was produced by a fragment (a meteoroid) from Comet Swift-Tuttle that impacted the atmosphere at about 212.000 km/h. The fireball began at a height of about 130 km over the province of Segovia, and ended at an altitude of around 75 km above the ground level over the province of Toledo.

The event was recorded in the framework of the SMART project, operated by the Southwestern Europe Meteor Network (SWEMN), from different observatories along the country. 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).
