A newly discovered asteroid designated 2018 BC will flyby Earth at a distance of 0.73 LD / 0.00189 AU (~ 282 739 km / 175 686 miles) on January 19, 2018. This is the second known asteroid to flyby Earth within 1 lunar distance since January 1, 2018, and 55th since January 1, 2017.
Asteroid 2018 BC was first observed at Catalina Sky Survey on January 17, 2018. Its estimated diameter is between 3.7 and 8.3 m (12 - 27.2 feet) and it belongs to the Apollo group of asteroids.

This asteroid will flyby Earth at 20:23 UTC on January 19 at a speed (relative to the Earth) of 2.67 km/s:

[ Ephemeris | Orbit Diagram | Orbital Elements | Physical Parameters | Close-Approach Data ]

This is the second asteroid to flyby Earth within 1 lunar distance this year after 2018 AH on January 2, 2018. While 2018 AH has an estimated diameter of 84 - 190 m (275 - 693 feet), making it the largest known near-Earth object to flyby Earth within 1 lunar distance since 2011 and the 9 th largest known near-Earth object (asteroids + comets) to flyby Earth within 1 lunar distance ever, 2018 BC's estimated diameter is only between 3.7 and 8.3 m (12 - 27.2 feet).

Its next flyby is expected at 08:07 UTC on May 21, 2019 at a distance of 0.39 AU.

A newly discovered asteroid designated 2018 BD flew past Earth at a very close distance of 0.10 LD / 0.00026 AU (~38 895 km / 24 168 miles) at 15:43 UTC on January 18, 2018, some 7 hours after it was discovered. This is the fourth closest approach to our planet since 2017 EA on March 02, 2017, 2017 GM on April 4, 2017, and 2017 UJ2 on October 20, 2017.
Asteroid 2018 BD was first observed at 08:24 UTC on January 18, 2018 at Catalina Sky Survey. This is a very small Apollo asteroid with an estimated diameter of 2.5 to 5.5 m (8.2 to 18 feet).

It flew past Earth at a very close distance of 0.10 LD at 15:43 UTC today, according to data provided by CNEOS. The Minor Planet Center has this asteroid flying past us at 17:27 UTC today.

[ Ephemeris | Orbit Diagram | Orbital Elements | Physical Parameters | Close-Approach Data ]

This is the 3 rd known asteroid to flyby Earth within 1 lunar distance since the start of the year and the 56 th since January 1, 2017. It comes just one day before the close approach of asteroid 2018 BC, discovered on January 17.

Its next close approach to our planet will take place at 20:37 UTC on November 19, 2018 at 0.33 AU. However, it won't come nearly as close as it did today for at least 115 years.

A very bright fireball illuminated the sky over Michigan, US at 01:11 UTC on January 17, 2018 (20:11 EST, January 16) and was followed by a sonic boom heard over a wide area. The USGS registered it as M2.0 earthquake just north of Detroit, Michigan.
The American Meteor Society (AMS) received 356 witness reports by 08:35 UTC from Michigan, SE Wisconsin, NE Illinois, N Indiana, N Ohio (US) and S Ontario, Canada.

50 people reported concurrent sound associated with the event and 114 delayed. Reports are still coming in.

This event was registered by the USGS as M2.0 earthquake just north of Detroit and reported as felt by more than 115 people. The image below shows the approximate location of the epicenter.

Local law enforcement agencies asked witnesses to stop calling 911 to report the meteor, saying they were tying up the phone lines.

"There is no need to call 911, it's a natural meteor fireball," the Ingham County's Office of Homeland Security and Emergency Management said in a Facebook post.

This event sparked so much interest that people coming to AMS website managed to crash it.

"Major event in Michigan. Server is getting overloaded. We'll be back ASAP, check back soon," AMS said and directed users to submit their reports to the International Meteor Organization (IMO). Since IMO and AMS share reports received, there was no fear of lost reports.

"We have calculated that this was a very slow moving meteor - speed of about 45 000 km/h (28 000 mph)," NASA's Meteor Environment Office said.

"This fact, combined with the brightness of the meteor (which suggests a fairly big space rock at least a yard across), shows that the object penetrated deep into the atmosphere before it broke apart (which produced the sounds heard by many observers). It is likely that there are meteorites on the ground near this region - one of our colleagues at JSC has found a Doppler weather radar signature characteristic of meteoritic material falling to Earth."

A very bright flash was seen over thousands of kilometers over Russia around 00:22 local time January 7, 2018 (20:22 UTC, January 6). The flash was followed by a ground-shaking explosion.
According to witness reports, the explosion was centered west the Ural Mountains, especially over Bashkortostan, Udmurtia, and Tatarstan but was seen over a vast swath of Russia.

Experts are still divided over the cause of the event. While some insist the phenomenon was not manmade, as officials deny there were any missile test or explosion at the time, there are also no reports of meteorites striking the ground.

Witnesses contacting The Siberian Times said they had a feeling something 'massive had happened.'

"It lit the night sky from side to side, making it look brighter than daylight," one eyewitness told the paper. "We saw this while driving. There was a vibration and the sound of an explosion in the sky. Awesome," another one said.

"A meteor burned out, not reaching the lower layers of the atmosphere," eyewitness Denis Rozenfeld told The Siberian Times. "Before this, it exploded and split into many small pieces. That is why there was such a sound, which came to us in a few seconds."

Astronomers from the Kazan Federal University agreed with Denis, saying that the event was caused by a meteor entering Earth's atmosphere and burning out before reaching the ground. "This was a bolide that burnt in the dense layers of the atmosphere, which is why it was seen over such a big territory, Dr. Sergey Golovkin said. "We didn't register the flash because there was a strong blizzard that night," he added.

While this might seem like the most plausible explanation, Yuri Nefefyeb, the director of the Engelhardt Astronomical Observatory, argued that the origin was atmospheric electricity, adding that this is still something not properly explained by science.

"There are a huge number of effects linked to atmospheric electricity, many of which are not properly studied because of how rarely they occur," he said.

Some scientists said the bright light flash was refracting from low clouds, while others suggested it might have been a dry thunderstorm.

The International Meteor Organization (IMO) received no reports about this event, as of 10:00 UTC, January 9, 2018.

This stunning Quadrantid meteor was spotted over Spain at 00:42 UTC on January 4, 2018 (01:42 local time), during the peak activity of this meteor shower. The event lasted about 6 seconds before the object disintegrated.
The meteor overflew the Mediterranean Sea. It began at a height of around 111 km (69 miles), and ended at an altitude of about 84 km (52 miles) over the sea.

The object was recorded in the framework of the SMART Project (University of Huelva) from the astronomical observatories of Sierra Nevada (Granada), Calar Alto (Almería), La Sagra (Granada), La Hita (Toledo), Huelva and Sevilla.

A major meteor shower is peaking January 3/4 with a potential to produce 50 - 100 meteors at its peak, up to 200 in perfect conditions. However, this assumes moonless dark skies and a right spot at the right time.
While some shooting stars associated with Quadrantid meteor shower are expected to be visible until January 6, the peak of this meteor shower lasts only a few hours. The reason is its thin stream of particles and the fact that the Earth crosses the stream at a perpendicular angle.

The Moon will be 17 days old and being so close to Full Moon, its light will severely limit the observations. However, Quadrantids are known for their bright fireballs, larger explosions of light and color, so the show can still be great for those patient enough to gamble with the uncertain peak. According to several astronomers, the peak this year might begin at around 21:00 or 22:00 UTC, January 3.

Their radiant, the point in the sky from which the Quadrantids appear to come from, is Bootes, originally a constellation called "Quadrans Muralis."

Unlike most meteor showers which originate from comets, the source of this meteor shower is a ~3 km-wide (1.8 miles) asteroid designated 2003 EH1. It was discovered on March 6, 2003 by astronomer and research scientist Peter Jenniskens who realized that 2003 EH1 is the source for the Quadrantid meteors.

A very large, slow-moving fireball meteor was observed over the United Kingdom at 17:33 UTC on December 31, 2017. The International Meteor Organization (IMO) received over 400 reports within 2 hours and the count now stands at 801. The event was as seen from northern Scotland to southern England, UK.
The object was green and red in color and was traveling east to west from the North Sea toward Sunderland and Carlisle for more than 10 seconds. 11 people reported delayed sound associated with the event, 11 a concurrent sound and 255 reported fragmentation.

"The object fragmented in smaller parts at the end of its luminous path, before vanishing," IMO's Karl Antier said.

"Rough automatic analysis of the reports received until now show the meteor started being luminous 80 km (50 miles) offshore Hartlepool, and traveled from east to the west to disappear 100 km (62 miles) onshore and 20 km (12 miles) South of England/Scotland border, halfway between Penrith and Carlisle (Cumbrie county). At the end of its luminous path, the meteoroid was nearly 50 km (31 miles) in altitude, which gives no chances for any meteorites to reach the ground," Antier added.
