A spectacular fireball over the Kanto region is captured by a camera set up in Yokohama by Atom teck. Inc. on the evening of Aug. 21.
A spectacular fireball lit up the sky over the Kanto region around 10:30 p.m. on Aug. 21.

Experts speculated that the meteor came in over the Pacific in Kanagawa Prefecture and fell on the southern part of the Boso Peninsula in Chiba Prefecture next to Tokyo.

A camera set up in Yokohama by Atom tech. Inc., a company that develops network camera apparatus, captured the dazzling fireball in all its glory.

Daichi Fujii, a curator at the Hiratsuka City Museum, said it was as bright as a full moon.

Gardai in Kilkenny received multiple calls on Tuesday night after reports of a loud bang in the city.

Dozens of residents in the south-east county said they heard a strange loud bang around 10pm.

The noise was believed to have come from near a cathedral in the City although no damage was reported at the church - KCLR96fm reports.

Many people took to Twitter to question what the noise was while some were so concerned that they phoned the Gardai.

One person said: "I felt it too, jumped off the sofa and outside to see what happened."

Comet 2

Space rock turning into a comet observed for the first time

Space Rock Turning into Comet
Space rocks called centaurs could someday become brilliant comets, like the one shown in this artist’s illustration. Astronomers have spotted a centaur that is expected to become a comet in about four decades.
Like the mythical half-human, half-horse creatures, centaurs in the solar system are hybrids between asteroids and comets. Now, astronomers have caught one morphing from one type of space rock to the other, potentially giving scientists an unprecedented chance to watch a comet form in real time in the decades to come.

"We have an opportunity here to see the birth of a comet as it starts to become active," says planetary scientist Kat Volk of the University of Arizona in Tucson.

The Chinese Meteor Monitoring Organization (CMMO) runs an automated camera in Shandong Province, monitoring meteor activity above the coast of the Yellow Sea. According to Spaceweather.com on Aug. 16th, it caught the brightest fireball in years. A space rock exploded in the atmosphere over the city of Linyi, turning the midnight sky blue.

"The meteor illuminated the whole earth and shook the landscape with a loud sound," reports CMMO staff member Zhou Kun. "The flash of light, which peaked at 22:59 pm local time, was widely observed across the Shandong and Jiangsu provinces of China."

A video of the event was shared on YouTube:

Meteor fireball recorded over Toledo, Spain

This bright meteor overflew Spain on 2020 August 14 at about 3:10 local time (equivalent to 1:10 universal time). It was generated by a rock from a comet that hit the atmosphere at around 86,000 km/h. It began at an altitude of about 107 km over the province of Toledo, and ended at a height of around 57 km. The total length travelled by the meteoroid in the atmosphere was of about 63 km.

The event was recorded in the framework of the SMART project, which is being conducted by the Southwestern Europe Meteor Network (SWEMN). The event was spotted from the meteor-observing stations located at La Hita (Toledo), Sierra Nevada (Granada), and Seville.

First appearances can be deceiving, and one of the latest comet discoveries by SOHO is the perfect example of that!

SOHO is no stranger to discovering new comets - via the NASA-funded Sungrazer Project, the observatory has discovered over 4,000 previously unknown comets since launch in 1995. Most of SOHO's comet discoveries can be categorized into families, or groups, the most famous being the "Kreutz" sungrazer group which accounts for over 85% of the Project discoveries. Only around 4% -some 175 comets- do not appear to belong to any known group or comet family. However, these are often among the most interesting comets and this most recent discovery -SOHO's 4,049th comet- was no exception!

The comet was first spotted on August 5th, 2020, by amateur astronomer Worachate Boonplod. At discovery, it was just a tiny faint smudge near the edge of the C3 coronagraph images recorded SOHO's Large Angle Spectrometric Coronagraph (LASCO) instrument. As it neared the Sun over the next day or so, the smudge became increasingly elongated, ultimately hinting that it may be two comets pretending to be one!

This was confirmed as the comets entered the narrower field of view of the LASCO C2 camera, where the improved resolution confirmed that not only was this more than one comet, it was actually THREE comets! The two main components are easy to spot, with the third a very faint, diffuse fragment following alongside the leading piece.

Meteor fireball seen over Prince Edward Island, Canada during Perseid meteor shower

Large fireball blazes across Nova Scotia's sky
People in Nova Scotia and Prince Edward Island in Canada spotted a 'fireball' streaking across the night sky on Tuesday, August 11, during the Perseid meteor shower, reports said.

Prince Edward Island resident Matthew Sentner shared this video showing the bright streak seen from Cavendish on Tuesday evening.

The annual Perseid meteor shower, likely to produce "a few meteors, including the occasional fireball," is best observed after midnight during the pre-dawn hours until August 24, NASA said.


Loud home-shaking boom in Saranac Lake, New York attributed to sonic boom

State Police say a sonic boom may have caused the explosive sound that rattled homes and businesses in the Adirondack Mountains Thursday morning.

The mysterious blast was heard at about 10:10 a.m. in the Saranac Lake area.

Troopers in Ray Brook said they were still trying to determine what caused the blast but said it appeared to be a sonic boom.

"It's sounding like there were jets flying over the area," Trooper Jennifer Fleishman said.

Fleishman said members of the State Police aviation operation heard the blast and said it sounded like a sonic boom caused when a jet travels faster than the speed of sound.

But so far, no regional air base was claiming responsibility.

Comet 2

New Comet C/2020 O2 (Amaral)

CBET 4822 & MPEC 2020-P10, issued on 2020, August 02, announce the discovery of a comet (magnitude ~18) by Leonardo S. Amaral (Rio de Janeiro, Brazil) on three 60-s CCD exposures taken on July 23 with a 0.3-m f/4 reflector. The new comet has been designated C/2020 O2 (Amaral).

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

Stacking of 16 unfiltered exposures, 90 seconds each, obtained remotely on 2020, July 27.05 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 8" in diameter (Observers E. Guido, M. Rocchetto, E. Bryssinck, M. Fulle, G. Milani, C. Nassef, G. Savini, A. Valvasori).
