Loud boom and reports of fireball sighting over Texas

https://www.sott.net/article/343795-Loud-boom-and-reports-of-fireball-sighting-over-Texas

bilene - Many people reported to KTXS that they saw a fireball moving across the sky Sunday evening just before 9 p.m. Most of the reports came from an area from Abilene to Snyder.

People in the Snyder region also reported hearing a boom like that of a transformer failing or a sonic boom that a jet might create.

Based on the reports, it appears that something fell from the sky and got close enough to the ground that the sonic boom it created was audible to people on the ground in parts of our area. However, we have not received any reports of anything crashing to the ground.

The object could have been man-made space debris like a piece from a spent rocket. But we have not heard of any of these reentries from NASA or our military. More likely it was a piece of "rock" wandering around in our solar system that fell into our atmosphere.

As the object falls deeper into our atmosphere friction with air molecules increases and heats the object. This creates the streak of light in the sky. Most of the time the falling object burns up before hitting the ground.Since the falling object is likely traveling at several thousand miles per hour, it creates a sonic boom. If it is close enough to the ground, we may hear it.

A newly discovered asteroid named 2017 EA flew past Earth at an extremely close distance of 0.05 LD (19 200 km / 11 930 miles) from the surface of our planet at 14:05 UTC on March 2, 2017. This is the 7th known asteroid to flyby Earth within 1 lunar distance since January 9, 2017. :o

2017 EA has an estimated diameter between 2 and 4.4 m (6.5 to 14.4 feet) and belongs to the Apollo group of asteroids. It was first observed at Catalina Sky Survey just a couple of hours before its close approach.

It flew past Earth at 14:05 UTC today at a speed (relative to the Earth) of 18.43 km/s.

This is the 7th, and the closest, known asteroid to flyby Earth within 1 lunar distance since January 9, 2017:

Asteroid 2017 DR34 - Distance: 0.57 LD - February 25

Asteroid 2017 DG16 - Distance: 0.34 LD - February 23

Is this what Mrshall has been talking about?

Exploding meteor fireball causes panic in Pakistan´s mountainous north!

https://www.sott.net/article/345381-Exploding-meteor-fireball-causes-panic-in-Pakistans-mountainous-north

A suspected meteor lit up the skies above Pakistan´s mountainous north late Wednesday, officials said, with panicked residents reporting a mysterious light whizzing past and the sound of multiple, powerful blasts.

The incident occurred around 9PM, when citizens in the city of Gilgit and the surrounding Ghizer and Diamer districts saw the bright object racing through the night sky above the region´s remote, soaring mountains.

"I saw a light flash through the sky and then there were multiple blasts," Ghizer district resident Javed Iqbal told AFP Thursday.

"I felt as if something had hit the roof of my house. I rushed outside with my family members and saw everyone getting out of their homes. The blasts had shaken the whole valley," he said.

His story was echoed by others, including Shabir Mir of Gilgit, who said he saw the object "disappear into the mountains", followed seconds later by what sounded like more than one explosion.

"I thought the object might have hit the mountain," Mir told AFP.

Social media was also flooded with reports of the incident, with some users posting unverified images they said were of the strange light.

Another large DAYTIME fireball!


A very large blue fireball illuminated the sky over Sweden around 20:30 UTC (21:30 CET) on March 20, 2017. The event was so powerful that the whole sky lit up, Swedish All Sky Meteor Network astronomers said.

Images of the event immediately started appearing on social networks, with people from the cities of Stockholm, Uppsala and Örebro all reported seeing the event. Reports from eastern Uppland mention sonic boom associated with the event.

"This is something that happens a few times a year," Eric Stempels of the Swedish Allsky Meteor Network project told The Local.

"Because it can happen during the day, when it is cloudy or far from populated areas, these events usually don't get much attention," he said, adding that this one fell in the north-eastern Uppland region.

Experts believe that this particular bolide may have been unusually large and Stempels estimated that it is possible it was between the size of a fist and a football.

Daytime fireballs are becoming more and more common!

https://www.sott.net/article/346122-Eyewitnesses-sought-of-bright-green-meteor-fireball-in-Irkutsk-Siberia

Scientists in the Russian city of Irkutsk (Siberia) are searching for people who could have witnessed the fall of a celestial body glowing bright green, Executive Director of the Irkutsk Planetarium Pavel Nikoforov told TASS.

"At 14:39 local time (11:39 GMT), while we were riding in a car along the bridge across the Irkut River towards the Leninsky district, we spotted an unusual glowing object in the daytime sky. It was speeding at a 45 degree angle, but its light went out in just a couple of seconds. We very much hope that Irkutsk's residents may have recorded this phenomenon using their car DVRs. We could collect these recordings and hand them over to scientists," he stated.

The fact that the celestial body was seen in the daytime, speaks volumes for its enormous weight, a source in the Astronomical Observatory of Irkutsk State University told TASS. "We assume that a celestial body weighing several kilograms could be glowing so brightly in the daytime. If we are provided with video recordings showing the bolide, then we could calculate its weight and trajectory," the source added.

In the autumn of 2016, residents of the Irkutsk region and the Republic of Buryatia witnessed a bright green meteor soaring above Lake Baikal. It was later dubbed the Baikal Bolide. Scientists believe that its weight was about 80 kilograms but because of its high speed it burnt up in the atmosphere.

Several fairly close flybys this month. Some of the closest end up being discovered just before approaching...

Social media lights up over meteor fireball in the night sky over Florida

https://www.sott.net/article/347154-Social-media-lights-up-over-meteor-fireball-in-the-night-sky-over-Florida

There are social media reports of a fireball over Tampa around 3 a.m. early Sunday morning.

A report on the American Meteor Society webpage confirms a similar possible sighting. According to Antonio Paris, an astronomer at MOSI, seeing meteors flying across the sky isn't unusual. (Well maybe yes and maybe not..)

Asteroid 2017 GM to flyby Earth at a very close distance of 0.03 LD!! :o

https://watchers.news/2017/04/04/asteroid-2017-gm/

A newly discovered asteroid designated 2017 GM will flyby Earth at a very close distance of 0.03 LD (~11 520 km / 7 158 miles) from the surface of our planet on April 4, 2017. This is the 15th known asteroid to flyby Earth within 1 lunar distance since the start of the year and the closest one. It is also among the 10 known asteroids to pass this close to Earth ever.

2017 GM belongs to the Apollo group of asteroids. Its estimated size is between 2.8 - 6.3 m (9 - 20 feet).

This small asteroid, first observed at Mt. Lemmon Survey on April 3, will make its closest approach to the Earth at 10:31 UTC on April 4 at a speed (relative to the Earth) of 18.48 km/s.

This is the 15th known asteroid to pass within 1 lunar distance since January 9, 2017, and the closest one!!

Bright Fireball over San Diego, CA

http://www.amsmeteors.org/2017/04/bright-fireball-over-san-diego-ca/

More than 260 reports from California, Arizona, Nevada and New Mexico
The AMS has received 260 reports so far (and counting…) about of a fireball event over seen over San Diego, CA on Monday, April 10th 2017 around 9:00pm PDT (April 11th – 04:00 UT.). The fireball was seen primarily from the San Diego area but witnesses from Los Angeles, Arizona, Nevada and New Mexico also reported the event.

Most of the witnesses describe the fireball as “green” and “very bright”. Only 7 witnesses so far heard either a concurrent or a delayed sound.

Strange report indeed ..

Fireball Spotted Off California Coast During Unusual Navy Anti-Sub Patrol
Missile test? Fireball near where numerous, low-flying sub-hunting aircraft circled ocean

https://www.infowars.com/fireball-spotted-off-california-coast-during-unusual-navy-anti-sub-patrol/

A “bright, pulsing orb” streaking across the sky was spotted off the California coast after US and Canadian anti-submarine aircraft conducted an unusual patrol of the area.

The green “fireball” occurred on Monday night near an area of ocean where numerous, low-flying sub-hunting aircraft, including a Navy EP-3E Aries II, a Navy P-3C Orion, and a Boeing P-8 Poseidon, spent several hours circling, a patrol which military observers described as odd and unlike routine exercises.

The exploding streak was bright enough for thousands of Southern California residents to see off the coast, and after local media reported on the orb, the National Weather Service claimed it was possibly a “meteor.”

“Something green lit up the sky right now. I’m in East Lake and I saw it and my mom in National City saw it too 20 miles away. Like a comet,” resident Travis Desmond told local news.
