Mystery object (possibly a meteorite) lands in UK garden after loud thump in middle of night

This mysterious rock like object is causing quite a stir in Lowercroft.

Now the couple in whose garden it was found are hoping someone may be able to shed some light on what it is — and where it came from.

Pauline and Norman Pollard were baffled to discover the striking black and yellow material in their garden, just days after hearing a loud noise.

Initially the couple thought it may be a meteorite - and don't know whether the noise is related to the find.

Mr Pollard, who lives in Lowercroft Road, aged 74, said: "We found it in the garden after we had heard a loud bang or thump in the middle of the night, it was like a car door banging."

Over 170 reports from IL, WI, MI, IN, OH, IA, NY, Ontario, KY and MN

The AMS has received over 170 reports so far (and counting...) about of a fireball event over seen over Wisconsin on Wednesday, February 6th 2017 around 01:27CST (07:31 UT.). The green fireball was seen primarily from Illinois and Wisconsin but witnesses from Michigan, Indiana, Ohio, Iowa, New York, Kentucky, Minessota and Ontario (Canada) also reported the event.

Asteroid attack? Yet another asteroid to give Earth a close shave

© ESA
Space rock block party!
For the fourth time since the start of 2017, a small celestial body will pass closer to Earth than the distance between us and the moon. Recently discovered asteroid 2017 BS32 zips by around midday Thursday.

This latest narrow shave comes just a few days after the closest such flyby in months, prompting observers and some astronomers to wonder if the apparent blitz of tiny planetoids could be more than mere coincidence.

According to astronomer Paul Cox at the Slooh observatory, the apparent bursts of small, close-approaching asteroids were first spotted just before buzzing us initially sparked discussion in 2016.

"One possibility sprang to mind -- that these clusters of smaller asteroids making close approaches to Earth over relatively short periods of time were in fact the fragments from larger asteroids that had broken up," Cox said via email. "However, when we reviewed the orbits of each of the asteroids, we found no correlation between them -- showing clearly they weren't associated in any way."

Cox said the scientists also looked for a connection to seasonal changes or to weather at observatories that might reduce discoveries of nearby asteroids, but there was no conclusive data to be found.

Close encounter! Asteroid discovered yesterday whizzed 70,000 km from Earth

The near-Earth asteroid 2017 BH30 was discovered by the Catalina Sky Survey in Arizona (USA) on 29 January 2017 and announced later the same day by the Minor Planet Center: it was going to have a very close encounter with the Earth, at 0.18 lunar distances (about 70.000 km).

At Virtual Telescope Project we captured 2017 BH30 while it was safely approaching us. Above is an image coming from the average of two 60-seconds exposures, remotely taken with "Elena" (PlaneWave 17″+Paramount ME+SBIG STL-6303E robotic unit) available at Virtual Telescope. The robotic mount tracked the fast (36″/minute) apparent motion of the asteroid, so stars are trailing. The asteroid is perfectly tracked: it is the sharp dot in the center, marked with two white segments.

To get these impressive results, the Paramount ME robotic mount tracked using the ephemerides retrieved via the JPL's Horizon webserver. At the imaging time, asteroid 2017 BH30 was at about 500.000 km from us and safely approaching. Its diameter should be around 5-10 meters or so.

The observations provided by the Virtual Telescope Project were published by the Minor Planet Center on its electronic circular MPEC 2017-B121.

Asteroid 2017 BH30 safely reached its minimum distance of about 70.000 km from us on 30 Jan. 2017 at 04:51 UT.

Over the years, our capability to detect small asteroids improved quite a lot, hence the apparently higher numbers of close approaches we see these days.

Comment: That would depend on how soon you want to detect them.

Meteor fireball observed across 11 southern U.S. states

If you saw a bright flash in the sky around 6:16 a.m., it wasn't lightning. It was a short trail, exploding fireball that lasted around three seconds.

Check out this still image captured by ArkansasSky.com near Greenbrier, Arkansas. They caught a big flash on their camera in the lower part of the sky between 20 and 30 degrees above the horizon.

There were several sightings in Collierville and scattered reports from Louisville, KY to Austin, TX. Check out the map to see all the sightings as of 9:30 a.m.


Comment: The American Meteor Society (AMS) received 120 reports about a fireball seen over AR, TN, TX, MO, OK, KY, KS, IL, NE, LA and MS on Monday, January 30th 2017 around 12:13 UT.

Meteor fireball spotted over Leeds, UK

The meteor over Allerton Bywater.
Is this a meteor in the skies over Leeds?

Kelly Moss snapped the burning light hovering over Brigshaw High School in Allerton Bywater at around 4.30pm on Wednesday, as dusk was falling.

A meteor, often called a shooting star, is the visible passage of a glowing meteoroid, micrometeoroid, comet or asteroid through Earth's atmosphere, after being heated to incandescence by collisions with air molecules in the upper atmosphere, creating a streak of light via its rapid motion and sometimes also by shedding glowing material in its wake.

Mysterious boom rattles San Diego residents

Several people across San Diego County reported hearing a loud, mysterious boom Tuesday afternoon.

An NBC 7 viewer told us, around 3:18 p.m., she heard two loud booms that shook the windows in her home in Santee.

There were multiple posts on social media of people reporting their homes rattled from the boom. The posts were from residents across the county, including Clairemont, Santee, and San Diego.

Some wrote that they suspected the sounds were caused by a sonic boom, but NBC 7 has not confirmed that.

Comment: Fox News San Diego reports two large "bangs" were heard. Residents also reported a car moving back and forth and a "large glowing ball in the western sky".

Brilliant green meteor fireball photographed over Southern India

While exploring the sky islands of the Western Ghats in 2015, molecular ecologist turned photographer Prasenjeet Yadav shot a rather rare photograph with a green meteor up in the sky and the twinkling lights of the town below. It earned him a plethora of awards, including National Geographic Nature Photographer of the year, 2016, and also an Honourable Mention in the Landscape Category by National Geographic. The photograph was shot on October 9, 2015, and Yadav was at the Nilgiri's near Ooty when he shot the green meteor. The town he is overlooking is Mettupalayam.

"This is probably the only composed photo of a green meteor. No photographer can plan this shot. This can happen for a fraction of second anywhere in the universe, and the fun part is, I was sleeping when my camera captured it. Everything else was hard work but for those 15 seconds, I was the luckiest photographer on the planet," says Yadav, who was working on a story on sky islands of Western Ghats when he shot this. Along with bird ecologist Dr Robin Vijayan, Yadav was working on a project to understand the role these mountains play in the formation of new species.

Born in Nagpur, Yadav went to Bangalore to pursue research at the National Center for Biological Science. In 2013, he moved to photography and began concentrating on environment and conservation stories. He is reportedly the only Indian to be represented by the National Geographic Creative. Although he has stepped away from the academic realm, Yadav considers himself a non-traditional scientist and often collaborates with researchers, policy makers and conservationists for his projects in the world of nature photography. Currently, he is working on a story on the sky islands of southern India for National Geographic and is documenting the unseen species of amphibians, reptiles, birds and mammals found only in the south Western Ghats.
