On July 25, 2017, YouTube user 'Meteors' uploaded footage of a meteor flying over the Mediterranean Sea on July 23rd.

It's the second fireball captured over the Mediterranean by the SMART Project in less than a week. The third since the beginning of July.

Meteor fireball caught on dashcam near Anchorage, Alaska

fireball
A meteor made a fly-by over Alaska at 12:43 a.m. Sunday morning, and it was all caught on dash-cam as it went streaking by!

A meteor is always a cool thing to see, but it happens so fast, that it is hard to get a good look let along a good photo or video. The sighting and flash of a meteor blazing through Earth's atmosphere usually lasts just seconds. You have to be in the right place at the right time with cameras rolling to catch one, and that was exactly the case for Philip Strumsky, who was driving on the Glenn Highway between Hiland Road and the weigh station, when he saw a flash in the sky.

There's a long list of things it wasn't, but no one can seem to figure out what it was.

A loud bang, described as an intensely close clap of thunder, was heard across the Nanaimo region Tuesday around 11:30 a.m. Hundreds of people reported hearing it, covering Nanoose to Hammond Bay to College Heights.

"Heard it and felt it near Lantzville," Jamie Penner said on Twitter, noting it was unlike the sound of blasting coming from his area in recent months. "It sounded like someone opening a big sliding door in an apartment above you."

"For me it was like a loud and quick thunder sound!," Donald Louch said.

On July 17th, YouTube user 'Meteors' uploaded video of a meteor flying over the Mediterranean Sea.


The fireball was recorded by observing stations operating in the framework of the SMART Project from the astronomical observatories of Calar Alto (Almería), Sierra Nevada (Granada) and Sevilla, Spain.

Comet 2

Comet: C/2018 N2 (ASASSN)

MPEC 2018-O01, issued on 2018, July 16, announces the discovery of a comet (magnitude ~16.1) in the course of the "All-Sky Automated Survey for Supernovae" (ASASSN) program, in images taken 2018 July 7-11 with the 14-cm "Cassius" survey telescope at Cerro Tololo. The new comet has been designated C/2018 N2 (ASASSN).

I performed follow-up measurements of this object, while it was still on the PCCP webpage. Stacking of 10 unfiltered exposures, 60 seconds each, obtained remotely on 2018, July 15.7 from Q62 (iTelescope network) through a 0.43-m f/6.8 astrograph + CCD, shows that this object is a comet with a diffuse coma about 15 arcsec in diameter.

On July 9th, a meteor fireball was recorded over Andalusia and the Mediterranean Sea by YouTube user 'Meteors'.
The event was produced by a fragment from an asteroid that hit the atmosphere at about 65,000 km/h.

The meteorite would have fallen into the sea, with a mass of just a few grams.

A bright meteor fireball streaked across the night sky over the state of Rio Grande do Norte, Brazil on July 7, 2018, around 10:35 pm local time (01:35 UT).

According to EXOSS Citizen Science Project the meteor was seen by residents of Mossoró, Areia Branca, Assú, Baraúna, Severiano Melo and even cities in Ceará such as Icapui and Russas said they had observed the event.

Meteor fireball seen across US Midwest evening skies

FIREBALL
Many Iowans were lucky enough to have their eyes to the sky Sunday evening around 8:45. A fireball or bright meteor was seen streaking across the southern sky.

Fireballs are meteors that burn much brighter than average meteors seen entering the earth's atmosphere. This is typical because of their larger size, but there are other factors that may make them brighter or appear in different colors.

NASA may have recovered meteorite from the ocean

Just two days into their search for a giant meteorite that crashed off the coast of Washington State, Dr. Marc Fries and the crew of the Nautilus have accomplished their mission: they believe they have successfully recovered pieces of the two-ton meteorite that created a huge fireball the size of a minivan as it streaked into the Pacific. Further analysis is in the works but - if these fragments are genuine - they'll be the first-ever pieces of a meteorite recovered from the ocean.

Based on Fries' calculations of the meteorite's trajectory, the Nautilus narrowed its search to a 0.4 square-mile patch of the ocean. The area was first searched with sonar, then with two ROVs (remotely operated vehicles) named Argus and Hercules. The team then used "a suction hose sampler, magnetic plate, and sediment scoop" to pick up the most promising pieces of rock.

The two fragments found so far are thought to be the outer shell of the meteorite (called the fusion crust) which the Nautilus Live blog describes as "meteorite exterior that melted and flowed like glaze on pottery as it entered the atmosphere."

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).

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