Asteroid 2018 GE3 flew past Earth at 0.5 LD
A newly discovered asteroid designated 2018 GE3 flew past Earth at a very close distance of 0.5 LD or 0.00129 AU (~192 981 km / 119 912 miles) on April 15, 2018. This is the 28th known asteroid to flyby Earth within 1 lunar distance since the start of the year and the second largest.

This object belongs to the Apollo group of asteroids. It was first observed at Catalina Sky Survey on April 14, just hours before its closest approach.

Asteroid 2018 GE3 has an estimated diameter between 48 and 110 m (157 and 360 feet) and it flew past February 15, 2013 Earth at a speed (relative to the Earth) of 29.58 km/s.

This is the 3rd known asteroid to flyby Earth within 1 lunar distance this month and the 28th since January 1. It is also the second largest known object to flyby Earth within 1 LD since the start of the year.

For comparison, an asteroid that exploded some 29.7 km (18.5 miles) above the Russian city of Chelyabinsk on damaging over 3 000 buildings and injuring over 1 500 people (mostly by broken window glass), had an estimated size of approximately 20 m (65 feet). Its light was brighter than the Sun, visible up to 100 km (62 miles) away.

Chelyabinsk asteroid, officially named Chelyabinsk meteorite, was undetected before its atmospheric entry, in part because its radiant was close to the Sun.

In the hours following the visual meteor sighting, a 6-meter (20 feet) wide hole was discovered on Lake Chebarkul's frozen surface and scientists from the Ural Federal University collected 53 samples from around the hole the same day it was discovered.

Snip: Video
Exoss Citizen Science YouTube channel reports of a fireball sighting in China:

A HUGE fireball (meteor) appeared over Jinghong city, China yesterday, June 1 (13:40 UT)! Sonic booms were reported, indicating the fireball likely penetrated lower than 30 km and quite possibly dropped meteorites!
Video: Xiao Jia Gong Gong via @Exos Citizen Science

Other local news outlets report the phenomenon was seen from Simao, that it was very bright, lasted about 2 seconds and was accompanied by two loud noises - presumably sonic booms. One Mr. Zhou from Dongfeng, Jinghong, heard the noise from inside his home.
In the video posted below the photographer can be heard exclaiming "What is this?!"

Fireball event in the Netherlands on Saturday June 16, 2018 around 21:09 UT was widely seen and reported.
IMO-report; AMS-report.

News report (Dutch only):
Tientallen meldingen over vuurbal in de lucht, ook boven Pinkpop

Translation:
Dozens of reports about fireball in the air, also above Pinkpop festival

Today, 14:24 Restated at 14:42

It only took a few seconds, but for dozens of people it was just long enough to see it. Last night a fireball was shearing through heaven and that did not go unnoticed.

The International Meteor Organization website received 90 reports from all over the country, but the phenomenon was also reported to have been seen in various places in Belgium, France and Germany. A visitor to Pinkpop saw the flash in the corners of his eye and recorded it on video (20 seconds) during a performance by American rock band Foo Fighters.

The video on Dumpert has already been watched tens of thousands of times. This festival visitor was one of the few to succeed in filming the meteorite. Not even experts have succeeded. "Our camera system was not yet operational, because it was still twilight," says meteorite researcher Marco Langbroek.

At various locations in the country there are cameras with a longer exposure time to capture meteorites in the dark. "In this way, we can determine which route it has taken," says Langbroek. "But if that thing comes during the day or at dusk, then it will be difficult.

That's why Pinkpop's film is very valuable, says the researcher. "That's fine, because it allowed me to establish that it wasn't a rocket launcher or an old satellite component. It was a real meteor, a piece of comet or something like that.
I could hardly believe it'.

The German Uwe Reichert succeeded in photographing the fireball. "It looked like a rocket, but it was much faster and pierced the clouds," he writes on Twitter. "At the time, I could hardly believe it myself. You don't plan to take a picture like that. The chances of success are probably even smaller than winning a lottery.


It happens a few times a year that a piece of space debris comes into the atmosphere and burns. "There's something to see every month, although it was brighter than usual," says Langbroek.

Last year

Usually it is a beautiful spectacle, but the researchers still keep a close eye on these kinds of phenomena. "If it's a relatively slow fireball and it stays low, there may be some leftovers and it may reach the earth's surface.

This happened, for example, last year (video, 49 seconds) in Broek in Waterland. A meteorite (news article in Dutch) descended by ten kilometres per second and ended up in a shed. The rock was ten centimetres in size and half a kilo heavy.

A huge meteorite just splashed into the ocean, and scientists want to find it
7.1.18 - 10:52AM
Residents of Ocean Shores, Washington, were startled on the evening of March 7 when a bright flash lit up the sky and a tremendous boom rattled the sleepy seaside town. “They thought it was a spaceship,” local resident Brittany Bryson told the Seattle Times.

It wasn’t a spaceship, but it was definitely a visitor from outer space. From analysis of radar signals, Marc Fries, NASA Cosmic Dust Curator, concluded it was a meteorite about the size of a golf cart that broke apart and splashed down into the ocean about 16 miles off the coast. Approximately two tons of fragments are likely scattered over a half-mile of seafloor.

“This is easily the biggest recorded meteor fall in the United States in 21 years,” Fries said.

Some of the debris that survived the plunge may be as large as a brick, and scientists want to retrieve as much as they can for further study. Luckily, a nearby research ship is in the middle of a survey mission, and they have some high-tech tools to aid in the scavenger hunt.

The Nautilus is the flagship of the Ocean Exploration Trust (OET), a nonprofit group founded by explorer Robert Ballard. Joined by scientists from the University of Washington, the Olympic Coast National Marine Sanctuary, and NASA, the Nautilus will use remote-operated submarines to survey the area and collect any fragments they find.


The debris field is situated near an underwater canyon about 400 feet deep. The area is relatively flat, making the dark-black meteorites easier to spot resting on the lighter seafloor. The OET, which previously discovered the wreckage of the Titanic, agreed to donate a day of their technical expertise to the endeavor. “It’s a great opportunity for us because it’s such an interesting, pure exploration type mission,” said Nicole Raineault, vice president of exploration and science.

Any meteorites discovered will be added to the research collection at the Smithsonian Institution in Washington, D.C.

The Nautilus also includes a high-speed satellite connection which is used to transmit video and other sensor data in real time to their mission control center at the University of Rhode Island. A live stream video of the expedition will be available at www.nautiluslive.org if you want to follow the search. The remote submarine dive is scheduled to occur between 9 am and 4 pm (Pacific Time) on July 2.

This meteor event was recorded over the south of Spain on 2 July 2018 at 3:58 local time (1:58 universal time). The event was produced by a tough rock from a comet that hit the atmosphere at about 118000 km/h. The fireball began at an altitude of around 99 km over the province of Malaga, and ended at a height of about 31 km over the province of Cordoba. The fireball was recorded by the meteor observing stations operating in the framework of the SMART Project from the astronomical observatories of Calar Alto, La Sagra (Granada), La Hita (Toledo), Sierra Nevada (Granada), Huelva and Sevilla.

Traces of 'Sonic Boom' Meteorites Found on Ocean Floor
July 5, 2018 11:21am ET

The first mission designed to hunt a meteorite that crashed into the ocean has now discovered what may be tiny fragments of the meteorite's crust, researchers say.

On March 7, three National Oceanic and Atmospheric Administration (NOAA) weather stations detected the fall of a meteorite about 15.5 miles (25 kilometers) off the coast of Washington state. "The fall was widely seen around local areas and widely heard around local areas — it came with some loud sonic booms," Marc Fries, the cosmic dust curator for NASA, told Live Science.

Fries estimated this fall might yield about 4,400 lbs. (2,000 kilograms) of meteorites. He also calculated the largest meteorite might weigh about 9.7 lbs. (4.4 kg) and have a diameter of about 5 inches (12 centimeters). [Crash! The 10 Biggest Impact Craters on Earth]

"This is the largest meteorite fall I've seen in 20-plus years of radar data," Fries said.

The details the scientists had regarding the fall suggested the meteorite was unusually strong, Fries said. This knowledge, in combination with the fact the meteorite landed on a soft seafloor as opposed to dry land, suggested this ocean fall might yield large, relatively intact meteorites for scientists to study.


Until now, scientists had never intentionally recovered a meteorite from the ocean, Fries said. In the past, researchers had accidentally discovered a couple of meteorites from drilling samples taken from the seafloor, he noted. However, this latest endeavor is the "first intentional search for meteorites from the ocean," Fries said.

Ocean Exploration Trust, a scientific research nonprofit organization, worked with scientists from NOAA's Olympic Coast National Marine Sanctuary, NASA and the University of Washington to locate any meteorites from this fall.

On July 1, the Exploration Vessel Nautilus investigated about 0.4 square mile (1 square kilometer) of water in the Olympic Coast National Marine Sanctuary, located off the coast of Washington state, sailing about 330 feet (100 meters) above the seafloor. The ship used multibeam sonar to map the seafloor, but the team "didn't really see any smoking-gun signature of a meteorite, any change to the texture of the seafloor," Nicole Raineault, leader of the expedition and the vice president of exploration and science operations at the Ocean Exploration Trust, told Live Science.

On July 2, the scientists deployed two remote-controlled submarines — the Hercules and the Argus — to investigate the seafloor. If the researchers saw anything interesting through the cameras of these remotely operated vehicles, they directed the robots to pick them up using either magnets or a suction pump.

The researchers did not spot any meteorites, as the seafloor was very soft, "and in all likelihood, any meteorites sank into the seafloor," Fries said.

However, after returning to the lab and spending 6 hours analyzing sediment, the team identified what seemed to be meteorite fragments in the last sample they had gathered, Fries said. "So far, we see two small fragments," he said.

"The meteorite fragments are small, melted pieces of rock," Fries said. Each about 2 to 3 millimeters [0.08 to 0.12 inches] large, they likely came "from the outside of a meteorite. When a meteor enters the atmosphere, it accrues what's called a fusion crust — "you have flash-melting of the rock, which coats the rock like pottery glaze," he said.

The reason Fries thinks these fragments are from the recent meteorite fall is that they are "basically made of glass, and such flash-melted glassy materialsdo not tend to last long in seawater." Moreover, these fragments "looked like they came from a small pit in the seafloor," Fries said. "It's some evidence that they came from something that fell."

Now, Fries and his colleagues will analyze these fragments in the lab to see what they are made of. "If they are meteoric in origin, we can tell what kind of meteorite they came from," he said.

Additional smaller meteorite fragments may lurk in sediment that the researchers collected. "We regularly deal with specks naked to the eye," Fries said. "We can deal with smaller things."

There are no plans to return to the site tolook for more meteorite fragments, but, Fries said, "I certainly wouldn't mind going."

This meteor event was recorded over Andalusia and the Mediterranean Sea on 9 July 2018 at 5:13 local time (3:13 universal time). The event was produced by a fragment from an asteroid that hit the atmosphere at about 65000 km/h. The fireball began at an altitude of around 89 km over the province of Almería, and ended at a height of about 31 km over the Sea. The analysis of its atmospheric path shows that this was a potential meteorite-producing event. The meteorite would have fallen into the sea, with a mass of just a few grams. The event was recorded by the meteor observing stations operated by the SMART Project (University of Huelva) from the astronomical observatories of Calar Alto, La Sagra, La Hita and Sevilla Jose Maria Madiedo (@jmmadiedo) | Twitter

Jupiter's Moons: 10 More Found, 79 Known - Sky & Telescope
By: Kelly Beatty | July 17, 2018
Jupiter’s Moons: 10 More Found, 79 Known
Over the past 18 months, astronomers have painstakingly tracked 10 tiny moons that they found circling the giant planet Jupiter.

After the discovery of Jupiter's four Galilean satellites in 1610, astronomers struggled to find 10 more in the 3½ centuries that followed. Today the IAU's Minor Planet Center announced that a search team led by Scott Sheppard (Carnegie Institution for Science) has identified 10 new moons of Jupiter, bringing the known total to 79 — the most of any planet in our solar system. Of those, Sheppard has led the searches that discovered 51 of them.

Dozens of Jupiter's moons circle the planet in a swarm of distant orbits and travel in a retrograde direction, that is, opposite that of the planet's spin. Their orbits cluster in three groups of 15 to 20 objects, named for members Ananke (discovered in 1951), Carme (1938), and Pasiphae (1908). Most likely each of these moonlet "families" represent fragments of larger precursors that were shattered by collisions early in Jupiter's history.


It's challenging to keep track of Jupiter's 79 known satellites. The planet's prograde moons (purple, blue) orbit relatively close to Jupiter while its retrograde moons (red) are farther out. One exceptions is Valetudo (green), a prograde-moving body that's far out. The 10 new finds announced today (along with two moons announced last year) are indicated with brighter colors. This animation shows the system in motion. Carnegie Inst. for Science / Roberto Molar Candanosa

Of the 10 new finds, seven of them are among these retrograde objects. Two of them orbit Jupiter in prograde directions (in the same sense as Jupiter's rotation) and appear to be members of a smaller group anchored by Himalia (discovered in 1904).

"Our other discovery is a real oddball and has an orbit like no other known Jovian moon," Sheppard notes in a Carnegie press release. Initially designated S/2016 J2 ("S" for satellite, "J" for Jupiter), it's far enough from the planet to be in the midst of the retrograde swarm. But this new find, provisionally named Valetudo, has a prograde orbit with an inclination of 34°.

Confusingly, Carnegie's press release describes 12 (not 10) new moonlets. But this higher tally includes S/2016 J1 and S/2017 J1, both of which were announced by the Minor Planet Center last year.

Valetudo was an exceedingly dim magnitude 23.9 when first spotted by Sheppard in March 2016. If its surface is only 5% reflective — typical for small outer-planet bodies — then this moonlet is likely less than 1 km across, making it Jupiter’s smallest.


With the exception of Valetudo, all of the new finds were swept up in early 2017, when Sheppard was on solo observing runs in Chile using the 6.5-m Magellan-Baade reflector Las Campanas and the 4.0-m Blanco reflector on Cerro Tololo.


"Jupiter just happened to be in the sky near the search fields where we were looking for extremely distant solar system objects," he explains. Sheppard, together with David Tholen (University of Hawai'i) and Chad Trujillo (Northern Arizona University) are one of the teams searching for a putative massive planet thought to lie far beyond Pluto.

Since then, follow-up observations have tracked them well enough to establish firm orbits for each object. Valetudo, in particular, becomes eligible for naming because it has now been observed during three oppositions of Jupiter. Valetudo is the Roman goddess of health and hygiene; she's a descendant of Jupiter and known as Hygieia in Greek mythology.

Sheppard's searches also swept up S/2003 J19, an object that had not been spotted since observer Brett Gladman (University of British Columbia) and others discovered it in 2003. It's one of 11 "lost" satellites of Jupiter (and seven around Saturn) whose orbits are so poorly known that they'll likely have to be discovered all over again. Fortunately, Sheppard told Sky & Telescope, "We found most of Jupiter's lost moons as well."

Characteristics of the 10 newly found moons of Jupiter are below. See Sheppard's Jupiter moons page for more discussion of the planet's clusters of prograde and retrograde satellites.

Meteor Reportedly Explodes Over US Air Base, Military Keeps Silence

NASA's Jet Propulsion Laboratory and the director of the Nuclear Information Project for the Federation of American Scientists have reported on the meteor, which produced an explosion with 2.1 kilotons of force. Units stationed at the missile-warning base, however, shared no information about this on their website.

Director of the Nuclear Information Project for the Federation of American Scientists Hans Kristensen has shared information about a meteor that burst just dozens of kilometers above the US Thule Air Base in Greenland that is designed to warn of potential missile attacks.

The original message about the explosion that Kristensen re-tweeted was posted by a user who described himself as a "space explorer at the Jet Propulsion Laboratory."

However, according to Business Insider, neither the 12th Space Warning Squadron based at Thule, the 21st Space Wing, nor the Wing's 821st Air Base Group from the missile warning Thule Air Base, which is intended to provide space surveillance and satellite command, reported publicly on the incident. >>>>>>> :scooter: :oops: Wrong EXIT! >>>>>>> :rotfl: >>>>>>>>
