Fireballs
Western Germany on Saturday witnessed a mysterious fireball darting through its night sky, as per the statement of some astronomers.
The bright streak caused by the fireball lasted about 5 to 7 seconds, ending in a jade (forest green) colour and diverging into two smaller blips, a witness at Siegen near Bonn had conveyed to the "fireball network." The said network is run by Berlin's Technical University (TU) and the German Aerospace Center (DLR).
"Most probably it was an asteroid fragment that had entered the atmosphere," said DLR fireball expert Dieter Heinlein on Sunday, linking the position of the spectacle the evening before to be over Kassel city in central Germany.
The fireball, believed to be a bolide -- a type of shooting star often compared to a full moon for its brightness -- could be seen clearly from parts of western and central Japan.
A man in his 20s living in Gifu Prefecture was able to capture the shooting star on camera as it momentarily lit up the sky at around 1:35 a.m. Sunday morning.
"It made a rumbling noise," one Twitter user wrote, while another said, "The sky went totally bright."
For this event, it received one video.

Carlos Fernando Jung, the south region director of the Brazilian Meteor Monitoring Network, said the meteor entered the atmosphere at an altitude of 64 miles and lasted 1.05 seconds before it blew up at 58.7 miles above the surface
The phenomenon was captured on camera by the Heller and Jung Space Observatory early Monday as it entered the Earth's atmosphere.
The center's surveillance system, located in the city of Taquara, recorded the the meteor exploding some 462 miles away near the border between Rio Grande do Sul and Uruguay approximately at 2:31am local time.

The resonant sound was first mentioned by a resident who posted a comment on the Gibraltar Life Facebook group page, with numerous people saying they heard and felt it, as well.
Several people said it sounded like thunder, but the sun was shining brightly, with no storm clouds in sight.
One person said it felt like a minor earthquake, but none were reported.
Others surmised that the sound could have resulted from blasting at a nearby quarry. Many residents said the boom shook their entire house.
Previously, other two fireballs were recorded, at1:47 and 2:21local time, respectively (Events # 2 and # 3 on video). The first of these (Event # 2 on video) was generated by a rock from another comet that entered the atmosphere at 202,000 km / h. It began at a height of 108 km over the Mediterranean Sea and ended at an altitude or around 72 km off the coast of the province of Almería (Andalusia).
Finally, the bolide recorded at2:21h (Event # 3 on video) was also produced by a rock from Comet Encke entering the atmosphere at 101,000 km / h. It began at an altitude of around 111 over the province of Ciudad Real, and ended at a height of about 71 km. These events were recorded in the framework of the SMART project, which is being conducted by the Southwestern Europe Meteor Network (SWEMN). These meteors were spotted from the meteor-observing stations located at Sevilla, La Sagra (Granada), La Hita (Toledo), Sierra Nevada (Granada), and Calar Alto.
Baffled northsiders took to social media to first see if they were imaging what had happened, asking others if they had heard the noise too, before trying to figure out what the colossal clang was.
And Royal Oak, Santry Court and Woodlawn residents are still none the wiser almost 12 hours after the big boom.
The thud had affects on houses in a 2km radius along the M50 in the area with many fearing it may have been coming from the motorway.
The fireball was caught on camera Thursday night across the Rio Grande Valley, an area of southern Texas and northern Mexico, including at the National Weather Service's Brownsville station.
For this event, they received 2 videos and 5 photos.
A livestream camera fitted to the research vessel Investigator, operated by Australia's national science agency CSIRO, spotted the fireball at 9:21 p.m. local time on Nov. 18. The vessel is designed to "look" down, performing mapping of the seafloor and conducting oceanographic studies about 60 miles south of Australia, but it was the meteor that flew by overhead that excited the crew on Wednesday.
"What we saw on reviewing the livestream footage astounded us, the size and brightness of the meteor was incredible," John Hooper, voyage manager onboard the vessel, said in a press release.
